I have a main page with one update panel
Inside that I have registered usercontrol. within this user control I have written some javascript
This js does not get rendered when page is loaded/opened.
Is there a way (without overriding Render) to get the Rendered HTML output of a UserControl? What if the UserControl as a control tree with other controls in it?
View 1 RepliesI have a webpage with two usercontrols. Usercontrol1 displays the time and the Session["Username"].
The default Session["Username"] is 'guest', which will change as soon as you are signed in. Usercontrol2 is the sign in form. The webpage doesn't cache so everytime you should get a "fresh" page?
The follow happens when a user signs in: In usercontrol1 the Labeltime gets updated but labelWelcomeUsername doesn't.

have a wizard control in an aspx page which is enclosed in a update panel. Each step in the wizard control is a user control. In one of the user controls I am using syncFileUpload control, and I am calling a JavaScript function "UploadComplete" on the
"OnClientUploadComplete". But when I run the program I am getting a javascript error "UploadComplete" not found.In the main user page I have
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Wizard ID="wzdDocAdmin" runat="server" ActiveStepIndex="0" BackColor="#F7F6F3" BorderColor="#CCCCCC" BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="0.8em" Width="100%" DisplaySideBar="False"> <StepStyle BorderWidth="0px" ForeColor="#5D7B9D"

I have a page that contains a user control. Can i make an ajax request directly to the control? I know I can make an ajax request to .aspx or .ashx; however, is it possible to go direct to the .ascx?
View 2 RepliesI just create a js file and write all my codes into it after i added this file to UserControl and after i get this UserControl's html i use $("#DivID").html(UserControlHTML);
Its working now.
Hi everyone;
Im using Ajax and Webservice to load UserControls. Its ok i can easily get the html code of UserControl but there is a problem.
For example UserControl's html code is something like that.
<h3>Header</h3>
<div id="content">
<p>lorem ipsum dolor sit amet...</p>[code]....
When i get this html code and insert it to an div's innerHTML.html looking as it should. But javascript codes which written on usercontrol not working.It should give me alert but its not.
I have a usercontrol that wprks fine as along as one instance is on a pageut as soon as i have two instances of it nothing works. I figured out that it could be the pageload function that adds handler for keydown and other that is the cause.As each instance is reproducing the same javascript in the viewsource.So can you tell me how can i make the usercontrol that it can have multiple nstances that have their own javascript pageload
View 4 RepliesI'm trying to manually call the ASP.NET (3.5) javascript postback function __doPostBack from my javascript code. The problem is that the postback script block, that is normally rendered right after the beginning of the <form> tag (and the hidden fields), is occasionally rendered near the closing </form> tag. Is there any way to force it to be rendered near the beginning of the form tag? Also, how does ASP.NET decide when/where to render the postback client script block?
Edit > Additional Info: The javascript code resides inside a user control that references the __doPostBack function. The control itself does not contain any 'postback controls' that would call that function. (When I mention 'postback controls', I mean ASP.net controls that call the __doPostBack function and not the asp.net ImageButton and Button controls)
Based on what I've observed and @Brian's comment on the dependency of the postback script on the availability of 'postback controls' on the page, I've found that when the page contains controls that cause postback, the __doPostBack script block is rendered after the opening <form> tag and when there are none, it renders them near the closing </form> tag (or according to this it's not even supposed to be rendered). Now it would make sense for ASP.NET not to render the postback script if there are no controls that require it, but the apparent position of the script near the closing tag is the one that still eludes me. I haven't been able to find any documentation that suggests this behavior. All I've been able to find was this.
Add a 'postback control' and set its visibility to hidden via css (not the Visible property). eg. <asp:LinkButton ID="RequirePostBackScriptLink" runat="server" style="display:none;" /> (this is what I'm using) Add the control to the Page.RegisterRequiresPostBack and implement the IPostBackDataHandler interface.
Finally, as @Jonathan_Bates mentioned in his post, the proper thing to do is to wrap the reference to __doPostBack inside a function that is an event handler to load (or ready if you're using jquery). That way, there wouldn't be a need to depend on the actual placement of the __doPostBack script.
I have a Java Script popup messae box that is displayed when an application user first displays the web page. Everything works great, but when the popup displays the background of the screen is white, with the popup in front of it. Instead I would like for the popup to be displayed in front of the web page after it has been rendered with all of the controls on it.
<%@ Page Language="C#" codebehind="Default.aspx.cs" inherits="Colso.Site.Default" masterpagefile="~/Master.Master">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
sb.Append("<script language='JavaScript'>");
sb.Append("alert('message to client')");
sb.Append("<");
sb.Append("/script>");
ClientScript.RegisterStartupScript(this.GetType(), "PopupSb", sb.ToString(), false);
}

I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

My Tab Container works fine on my development machine. But it doesn't show up my production machine. On closer inspection, the Production machine renders it as hidden. Any thoughts on why this would happen?

Visible="true" ActiveTabIndex="10" EnableViewState="true"
CssClass="NewsTab" Width="100%">
Rendered:

Here is (more) code that demonstrates the issue. If the control in the host page is removed the tab control renders correctly. Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link. Is this broken or am I doing something wrong?

There seem to be about a zillion posts on similar situations, but I can't seem to find an answer in any of them. I've tried numerous techniques that I've seen, but nothing is making a difference. I have a Master page with an UpdatePanel with a ContentPlaceholder. In the content page I have a calendar. Above the calendar are LinkButtons that trigger a Command event to switch between Day Week and Month views. In the calendar DayRender event I am adding items to each day of the calendar. Items are pulled from a database. All items are contain within a dynamically generated div to help with layout. Each event that is added is a hyperlink that takes the user to a page where they can edit details of the event.
If there are more than 4 events, I'm adding a LinkButton with the text, "(more...)". I'd like that to trigger a Command event so that I can switch to the Day view of the appropriate day:
[Code]....
The problem is that, while the anchor tag gets generated with the proper text and ID, no href attribute is rendered and, as a result, nothing happens when you click "(more...)". I've tried switching to a Click event, but it does the same thing. (And I need the Command event to use the code I already have in place for some other buttons.) I've tried rendering it as an asp:Hyperlink and using ClientScript.GetPostBackClientHyperlink. That gives me a hyperlink, but I don't know how to get it to trigger so it results in the server interpreting it as a Command event and linking it to the proper event handler.
I have downloaded the latest version of AJAX toolkit (AjaxControlToolkit.Binary.NET35) and add to asp web page as I did many times before without any particular problem. However this time I'm experiencing unwanted results that make me want to through the computer into my neighbor's pool. The tab control is rendered with the following inline style:
<div style="width: 500px; visibility: hidden;" id="TabContainer1">
I seem to have come upon an issue with XHTML 1.0 Strict compliance and ASP.NET AJAX. When a ScriptManager is included on the MasterPage, it renders the following tag:
<input type="hidden" name="ctl00$SCManager" id="ctl00_SCManager" />
In order to be XHTML Strict compliant, this tag must be included in a <div>, as is the VIEWSTATE. Even when Strict compliance is enabled in the web.config, the ScriptManager insists on rendering in a non-compliant way. This is currently blocking our transition to Strict mode, as it's the only non-validating tag on our pages.
i designed an user control within that one html textbox input control is there. now i want to drag and drop this usercontrol into an aspx page, my doubts is how can i validate that user cotrol html input control has data or not using javascript? then im want to read that data from aspx code behind, how to do this?
View 6 RepliesAt first, I should confess that I am not sure if it is a good practice or not. I have came out with the idea due to my practice of jQuery.ajax().
What I want to achieve is depended on this design:
//Server Side; an .asmx file contains a method like this:
[WebMethod]
public string NewContent(string parameter)
{
string renderedHTML = string.Empty();
switch(parameter)
{
case ("person"):
// create an asp.net panel with
// some controls in it that has form elements to enter person data
// render control and assign its html to renderedHTML
break;
case ("department"):
// create an asp.net panel with
// some controls in it that has form elements to enter department data
// render control and assign its html to renderedHTML
break;
}
}
And from the client I want to do this:
// Some html in the page
<script type="text/JavaScript">
jQuery.post('ajax/myWebServices.asmx/NewContent'
function(returnedPanelContent) {
$('.result').html(returnedPanelContent);
});
</script>
Question is:
How can I make it work? Briefly to have a webservice method that returns different asp.net Panel control content created programmatically so that I can get this control rendered as HTML in my client-side and insert it to my web page?
I have a UserControl, ASPX page, a Class file and a JS file. In Class file, I have a method for building and registering textbox controls:
ScriptManager.RegisterClientScriptBlock(this,
typeof(Page),
"onfocus", jsText.ToString(),
true);
jsText is nothing but Name and Value pair strings. Example : "KEY1:txtName, KEY2:txtDOB" In UserControl, I am calling the above Class method to pass all the textboxes and calling the JS file to validate the registered controls. Then, I am calling that Usercontrol in ASPX page. Here I am unable to validate the controls as it is saying "KEY is undefined".
I have a UserControl with two labels and a slider control on it. I have a javascript function that is called when the value of the slider changes, and it is supposed to update the text of the labels. The ascx code is:
asp Code:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="AlignSlider.ascx.vb" Inherits="F1TimeTrials.Controls.AlignSlider" %><%@ Register assembly="Infragistics35.Web.v10.2, Version=10.2.20102.1011, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.Web.UI.EditorControls" tagprefix="ig" %> <script type="text/javascript" id="igClientScript"><!-- function sliderControl_ValueChanged(sender, eventArgs) { var leftLabel = document.getElementById('<%= Me.lblLeftValue.ClientID %>'); var rightLabel = document.getElementById('<%= Me.lblRightValue.ClientID %>'); var maxValue = sender.get_maxValueAsDouble(); var value = eventArgs.get_newValue(); leftLabel.innerHTML = value; rightLabel.innerHTML = maxValue - value; }// --></script> <asp:Table ID="table" runat="server"> <asp:TableRow runat="server"> <asp:TableCell runat="server"> <asp:Label runat="server" ID="lblLeftValue" Text="0" /> </asp:TableCell> <asp:TableCell runat="server"> <ig:WebSlider ID="sliderControl" runat="server" ValueType="Double" > <ClientEvents ValueChanged="sliderControl_ValueChanged" /> </ig:WebSlider> </asp:TableCell> <asp:TableCell runat="server"> <asp:Label runat="server" ID="lblRightValue" Text="100"/> </asp:TableCell> </asp:TableRow></asp:Table>
When I put this control on a page it works just fine. I drag the slider, the labels update with the new values. However, I actually need a large number of these controls on my page (around 10-20 I think), and this is where the problems start. When I change the slider on one of these UserControls, it changes the text of only the labels in the LAST instance of this UserControl on the page. It seems that the 'document.getElementById' function actually searches through the entire page rather than just the one UserControl. How can I fix this? How can I get the two label controls from this current UserControl instance, and not any other instance on the page?
I have created a User Control with 4 check boxes(server control).I want to allow to check only one checkbox out of four.
The user control is loaded on page dynamically.I page may have multiple same UserConrol.
How do I do it using Jquey or Javascript?
I'm working on an ASP.NET app.I'm using a UserControl for a year calendar.This UserControl has 12 asp.net calendar controls (for the 12 months of a year)
I'm trying to build a jscript function that can access to one (or more) of the 12 month calendar, but I can't access them.
example:
"<asp:Calendar ID="CalendarJanuary" runat="server"></asp:Calendar>"
here's my function
function SetCalendar(controlId) {
document.getElementById(controlId+'_CalendarJanuary').VisibleDate = somedate
}
but this is allways throwing an error:'Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object'
it seems is not finding the calendar and I'm sure i'm passing the right controlID
I have a web form that contains a usercontrol and I would like to be able to access the html elements within the usercontrol from the form page using javascript.
I tried the following:
document.getElementById('<%= usercontrol.clientid %>')
but this returned null.
I had a look around with firebug and found that the tags in the usercontrol render with clientids like usercontrolid_myelement. I'm guessing that something like this might work:
document.getElementById('<%= usercontrol.clientid %>'+'_myelement')
I have one user control in page, and inside this have UC2 (modal pop up). And I try to achieve this: When I close UC2(modal) i try to update some fields on UC1. And this works fine for one(I have UC2(modal) and on button Save OnClientClick="SaveInfoCI()"), and in UC1 on top of page
function SaveInfoCI() {
document.getElementById("<%=frmData.FindControl("txtImplementingCI").ClientID%>").value
= document.getElementById("<%=UC2.GetClientID%>").value; }
but because i reuse this control in another place i want to update another field. Basically now i Have 3 JS function that update 3 fields. And I try when I click save in UC2(modal) I must execute one of this 3 javascript f, to update right field. I don't want to have 3 same UC with only difference in OnClientClick="SaveInfoCI().
I've searched high and low for some resolution to this problem. Hopefully someone here can explain!!I create a usercontrol that uses .NET web controls, but I want to create a smoother user experience by avoiding full postbacks, so I write some JQUERY to capture click events on the client and in this way do the processing without going back to the server.
$("#tblLedgerEntries :checkbox").click(function () {
var value1 = $(this).closest("tr").find("td.invoiceAmount").html();
var value2 = $('#<%=hdnTotalToPay.ClientID%>').html();
CalculateTotalPayable(value1, value2, $(this).attr("checked"));
