My main question is How to access specific control info from UserControl
How do I access the Control (dropdownlist) in current Page from the UserControl? In the UserControl:
String test = ((DropDownList)this.Parent.FindControl("drpdwnlstMainRegion")).SelectedValue;
or
String test = ((DropDownList)this.Page.FindControl("drpdwnlstMainRegion")).SelectedValue;
It return null on ((DropDownList)this.Parent.FindControl("drpdwnlstMainRegion")) for some reason? BTW ... I am using ASP.NET C# 3.5.
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?

View 1 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(),

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".

How to access to an HTML control runat server from JavaScript
I've a JavaScript function in my page through which i make some elements in the page as 'JQuery UI droppable'.
function setDroppableTargets()
{
$(.cssDockZone).droppable();
}
But the elements with the class cssDockZone is created dynamically upon user interaction. So in the code behind i create the control first and finally at the end i register a scriptblock which calls setDroppableTargets().
//set droppable targets ClientScript.RegisterClientScriptBlock(this.GetType(), "setDroppableTargets", "setDroppableTargets()", true);
But the javascript function is invoked before the controls are created eventhough i register the script at the end (after creating the controls) and i cross checked it by getting the elements with class name '.cssDockZone' and i getting it as 0.
$(.cssDockZone).length
I have some ajax fucntions on my default.aspx that I use for saving data to my db. I have the form on my web control. When I try calling the function from my button which resides on the web control. I get an error.
I need to call that function from my registerform.ascx. How do I do that from within the registerform code behind?
function ShowAvailability() {
$.ajax({
type: "POST",
url: "Default.aspx/CheckEmail",
data: '{usermail: "' + $("#<%=subs_email.ClientID%>")[0].value + '" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
failure: function(response) {
alert(response);

I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.
I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.
alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.
I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.
objBLL.Latitude= DirectCast(uc_MyClient.PickupHidLat, HiddenField).value
why is the value null on the content page?

My problem is that the <Content> and <AlternativeContent> doesn't get rendered as Panels and on the Client side its rendered as the initial tags(<Conten>) and not a div or whatever a asp:Panel normally gets converted to.
I struggled with some javascript issues, and discovered that the problem seemes to come from a failed ajax control access. Here's my problem: I have a master page and a content page.In my content page, I have an accordion with 2 panes. 1rst pane: a textbox and a validation button; I want the button to fire javascript function without reloading page (using "return false;");
In my master page, I put my ToolkitScriptManager.
In my content page, I put my script containing the functions.
The problem is that it seems like I can't access the accordion control in my js functions, whereas I can access my textbox value. ere is my source:
[Code]....
All I want is, that when clicking on button OR changing to 2nd pane, it checks the textbox (function check()), if fails, then doesn't open 2nd pane, stays on 1rst, if not, then closes 1rst and changes to 2nd pane.
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.

Here is the code snippet:
function CheckUpload() {
var flag = validatePage();
var Checktext = $("#HyperLinkUploadFile").val();

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.
I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2
