I thought I heard we would be able to get the value of an asp:textbox by id with javascript in the .net 4 framework? was I mistaken? if not does anyone know the syntax?

I have a website which is hosted on GoDaddy they have version 4.0 runtime. The issue is the client id of the server controls are generated as "contentPlaceHolder1_drpBanks" where it was earlier (when the website was on some other server) getting generated as "ctl00_contentPlaceHolder1_drpBanks".
What I need to know is there a way to resolve this so that I don't have to make any changes in the code.
Like a setting in web.config file or something.
I'm trying to get the Google map API to work with ASP.NET. I got it working on an HTML page but it does not work on a ASP.NET master page/content page. The problem seems to be getElementById not finding a div assigned to an ID.
View 3 RepliesI am simply trying to store a label in a variable in javascript but for some reason this isn't working with document.getElementById('control');. I know my javascript is linking to my html file fine because everything else works.
Here is my javascript code:
function performEvapCooledCircuit(txt)
{
var error = document.getElementById('lblError');
if (txt.value == null || isNaN(txt.value))

I've got a basic web form page which I use 2 user controls on. The first control has the second nested within it...
On my first popup.ascx i have the following javascript validation

txtDate works fine so is there some issue with having nested user controls and using getElementById I'm missing?
I get the ClientID of a control in ItemCreated event like this: 'ctrl0_spanLoader'
and when it is rendered like this (from view source of IE): 'CtlCategory1_ProfiledBasedSearchResult1_ListViewSearchResult_ctrl0_spanLoader'
This happens in Asp.Net 4 and I have no problems in Asp.Net 3.5.
How do I get the real clientID from ClientID property of my control? Is it a matter of configuration or anything else?
i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function.
On the HTML code is rendered only the first view or the view that is activated on page load.
Is there any way to find a control inside the view using javascript? or I am doing something wrong?
Is it possible to get a Label's text property in javascript using the clientID? I know with a text box you can do:
var test = document.getElementById("<%=txtUnread.ClientID%>").value;
But Label's get converted to span's which don't have a value.
I trying to write a javascript generate <%= element.ClientID% > where element is one of the input parameter of function. I am trying to write a variable
var elementName = "<%=" + element + ".clientID%>"

I have Telerik RadGrid with a custom edit form. In my edit form there is a RadDatePicker to which I have added a custom footer template containing a 'Today' button. In the OnClick event of the button I call a Javascript function which takes the control ID to set the selected date. However, because the control is inside the edit form there is no variable created for it and the compiler throws an error when I try getting the client ID. The RadDatePicker is declared with:
<telerik:RadDatePicker ID="ControlName" runat="server" SelectedDate='<%# Bind("Field") %>'>
<Calendar ID="Calendar1" runat="server">
<FooterTemplate>
<div style="width: 100%; text-align: center; background-color: Gray;">
<input id="Button1" type="button" value="Today" class="button"
onclick="GoToToday('<%= ControlName.ClientID %>')" />
</div>
</FooterTemplate>
</Calendar>
</telerik:RadDatePicker>
The error I get is CS0103: The name 'ControlName' does not exist in the current context on the line referencing the ClientID. Is there another way in which to get the ID to pass to the Javascript function?
I have a gridview and template field (textbox) control. on GridView_RowDataBound I want to find the control and pass the control id to a javascript which will set datepicker on that textbox here is how I am doing but its not working.

I am developing a user control (ascx) in ASP.NET which uses javascript for manipulating controls. Currently the javascript code is inlined and uses <%= somecontrol.ClientID %> to get the control it needs.
I want to put the javascript file in external file but from external file I cannot use the above syntax for retrieving controls. I have read about possible solutions in this and this answers but the problem is that the user control can be placed multiple times on page. This means that the Controls array (mentioned in the answers) will be rendered several times with different items. As a result the script will not be able to retrieve the id it needs. If I put <%= ClientId %> in the name of array that holds items then I will have the same problem as I am trying to solve.
On load I'm both calling a JavaScript setTimeout() function that will hide a .NET Panel control, and hiding it in the code behind on first load. Clicking the save button will set the Panel to visible then reload the page at which point a setTimeout() function is called... so basically you click save, and see a panel with "Details Saved" for three seconds, at which point it disappears.
The problem is the external JavaScript file can't find _pDivAlert.ClientID (I've debugged and it returns null). It only works when the code is in a tag in the .aspx page. how I can either pass the client ID to the HideControl() function or find the ClientID from the external JS file?
Here's my code:

I have a databound gridview that displays basic customer information. I have added a template field to the gridview, but I am having trouble with the coding for the RowDataBound event. I need to take the sum of all payments made by the customer in each row and store it in a variable for further calculation. Also, I need to take an integer value (say 30, representing 30 days) and add it to a date, and return a date.
View 14 RepliesI have a usercontrol that hides a div when a button is clicked.
<asp:LinkButton ID="lnkbtn" OnClientClick="ShowHide(); return false;" runat="server" />
<div id="popupPage" style="display:none;">
</div>
function ShowHideGotoPopUp() {
var ob = document.getElementById("popupPage");
if (ob.style.display == "none")
ob.style.display = "block";
else ob.style.display = "none"

There is a problem when I place on page more then 1 usercontrol, all controls has div with same id = popupPage.
I thought I heard that in .net 4 we would be able to reference asp:textbox's by id and not have to use clientid to get the value. I can't find this documented anywhere. Just wondering if anyone knows if this works and what the syntax is?

I am also using Master Pages.
I have a label "lbl1" that I am trying to locate in a content page from the Master page. I want to do it dynamically so I am trying to pass the name of the control (which in this case is lbl1) through as a parameter. I don't get an error, it just doesn't work. If I do an alert to see what the string "temp" looks like, it is correct, but iit seems as if Javascript ignores it. I believe it has something to do with the '<%= not being interpreted correctly by the browser I'm sure it is a simple solution, but I can't figure it out!

I have a page with some datasources in it. I am doing reenginering of the page itself and would like to split some parts of the page in several user controls. In my code I have an ObjectDataSource object with the following params
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
TypeName="DataSetTableAdapters.PhotosTableAdapter"
SelectMethod="GetPhotosForAlbum">
<SelectParameters>
<asp:ControlParameter Name="albumID" ControlID="txtAlbumID" Type="Int32"/>
</SelectParameters>
</asp:ObjectDataSource>
This piece of code automatically bind the hidden field "txtAlbumId" to the datasource. In my revision this datasource should be moved to a user control. What is the best way to handle a scenario like this?

I just like to know how to pass a parameter to the datasource of my dllItemCodeFooter and dllItemCodeEdit Drowndownlist which calls my getItemCodeList(decimal categoryID) method in the code behind. The value of the parameter will be seletectedValue of the first dropdownlist ddlCategoryFooter or ddlCategoryEdit).I know it could be done in code behind, but i prefer to bind my datasource in asp page. I want to achieve something like this DataSource='<%# getItemCodeList(ddlCategoryEdit.Seletected)%>'
