View 6 RepliesI 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 javascript embedded in my extended gridview control that reference the grid control. Example:
[Code]....
HTML code:
[Code]....
way to determine the gridview object in javascript. I want to make it generic so that if I use this gridview in any other control it should work instead of hardcoding the name.
I need to access controls of aspx page and usercontrol page through the external .js file. I created a global varaible in the aspx page
<script language="javascript" type="text/javascript">
var loadPanelID = "<%=ajaxLoadingPanel.ClientID%>";
</script>
Now I pass this value in the onclick event of button click (Let the funtion name be Fun(loadPanelID) ) . The controls is recognised in the .js file. Everything is fine till now. Now i need to call the same javascript method Fun() from the button click of usercontrol.
<script language="javascript" type="text/javascript">
var loadPanelID = "<%=ajaxLoadingPanel1.ClientID%>";
</script>
I have ajaxLoadingPanel1 in the usercontrol and I have defined global variable as in the first one in ascx and passed that value to Fun() method. But this time it gives error called "loadpanelID" is undefined.
I have an asp.net page that has menu which loads user control dynamically when the menu item is clicked.Now in the user control i have some buttons calling javascript on clientClick.When i click this button,it throws javascript error
Microsoft JScript runtime error: '(function name)' is undefined
Here is the code snippet:
function CheckUpload() {
var flag = validatePage();
var Checktext = $("#HyperLinkUploadFile").val();
if (Checktext != '' && flag)
flag = true;
return flag;
}
<asp:LinkButton ID="btnNotifyOA" runat="server" Text="Recommend Award and Notify OA & AO"
ValidationGroup="Notify" OnClick="btnNotifyOA_Click" OnClientClick="return CheckUpload();" />
The above linkbutton and javascript is inside a usercontrol.
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 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 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.
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"));

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 have a user control which acts as a footer for my website and uses java script jqdock.js to show apple type bottom menu. I added an update panel to the usercontrol. What problem I am having now is, it works fine initally but once I click the mail button which is in the usercontrol , the whole user control dissapears, after postback i guess. below is the usercontrol and code view:
enter code here
public void Page_Load(object sender, EventArgs e)
{
// Page.ClientScript.RegisterClientScriptInclude("bottomMenu", "../js/jqDock.js");
ScriptManager.RegisterClientScriptInclude(this,this.GetType(),"bottomMenu", "../js/jqDock.js");[code]....
This is page load
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{ [code]...
But in my ascx.cs when IButton1_Click is trigered My name is null
private string _sname;
protected void Page_Load(object sender, EventArgs e)
{ [code]...
im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
View 5 RepliesI have 1 ModalPopupExtender inside a UserControl. Everything works great until I start adding the same usercontrol to the page. I am getting this error message in the javascript console::
Message: Sys.InvalidOperationException: Two components with the same id 'MPE1' can't be added to the application. I understand the error, it obvious that the framework wants unique IDs. What I can't figure out is how to give them unique name.
I 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.
There are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.
View 5 RepliesI need to insert some JavaScript code inside a UserControl that I load from an Ajax call via jQuery Ui Tabs. Let me explain... This is my View (with jQuery loaded)
<script type="text/javascript">
$(document).ready(function () {
$("#tabs").tabs({
cache: false,
});
getContentTab (1);
});
function getContentTab(index) {
var url='<%= Url.Content("~/Home/getUserControl") %>/' + index;
var targetDiv = "#tabs-" + index;
$.get(url,null, function(result) {
$(targetDiv).html(result);
});
}
</script>
<div id="tabs">
<ul>
<li><a href="#tabs-1" onclick="getContentTab(1);">Nunc tincidunt</a></li>
<li><a href="#tabs-2" onclick="getContentTab(2);">Proin dolor</a></li>
<li><a href="#tabs-3" onclick="getContentTab(3);">Aenean lacinia</a></li>
</ul>
<div id="tabs-1">
</div>
<div id="tabs-2">
</div>
<div id="tabs-3">
</div>
</div>
With these lines of code I call the Ajax function to load the content into a DIV.
This is the Action from the controller:
public ActionResult getUserControl(int num)
{
return PartialView("TestUC", num);
}
And this is the UserControl...
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
Number... <span id="testSpan"><%=Model.ToString() %></span>!!
<input type="button" value="Click me!!" onclick="message();" />
<script type="text/javascript">
function message(item) {
alert($("#testSpan").html());
}
</script>
The problem is that the message() function returns always 1 (instead of returning the correct number). My question is... How should I add the script to my UserControl in order to have my code running correctly?
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 have an asp.net usercontrol located on on my aspx page. In the usercontrol there is a javascript function that I would like to fire everytime the page that contains the usercontrol submits to the server. (directly before this happens) Ideally I prefer to not have to write any code in the parent to make this happen, but I am not sure what the usercontrol may be capable of at this time. Can the usercontrol know that the page is submitting to the server and fire the function before this happens? Is there some sort of event that takes place here?
