Web Forms :: Rendered ClientID Is Different From Programmatically Retrieved ClientID
Sep 26, 2010
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 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.

found that when I get the Request.Form("__EVENTTARGET") on a postback and compare it to Control.ClientId it is not equals.
ctl00$ContentPlaceHolder_MainContent$DropDownList_CantidadAcompanhantes
ctl00_ContentPlaceHolder_MainContent_DropDownList_CantidadAcompanhantes
My Code:
[Code]....
This line "If ctrlName = DropDownList_CantidadAcompanhantes.ClientID Then" is never equals.

I am trying to create a listing for a ticket company. When the user(client) adds a new ticket to the listing, all the ticket info is saved into the database table, but I can't figure out how to get their clientID in the table with that post. For example, I have event, date, venue, row, section etc...all this info gets stored, but I need to have the clientID stored also, so the gridview can show the post when the client logs in/out from the app. Right now the only way the clientID is in the DB is because I manually put it there for development reasons. But, when the client adds a new item to their listings, it does not show until I put the ID in myself. I need the ID to insert in the CID column at the same time the rest of the info is stored.

I have a page that belongs to a master page, and I'm having trouble getting the correct clientId to use in javascript. I have a textbox defined as:
<asp:TextBox ID="ui_tbDOB" runat="server" Width="75px" onchange="SetAge();"></asp:TextBox>
In my javascript SetAge() function I go to get the field by doing this:
var ui_tbDOB = document.getElementById('<%=ui_tbDOB.ClientID %>');
When I view my page source my textboxId ends up being:
<input name="ctl00$cphMainBody$ui_tbDOB" type="text" value="06-06-1983" id="ctl00_cphMainBody_ui_tbDOB" onchange="SetAge();" style="width:75px;" />
All good so far, except that my javascript ends up being: var ui_tbDOB = document.getElementById('ctl00_cphMainBody_ui_tbDOB');
, the two don't match up, and my javascript fails:
'ctl00_cphMainBody_ui_tbDOB' is not equal to 'ctl00$cphMainBody$ui_tbDOB'

If I have a checkboxlist where I insert a clients clientid and a number of interests they check off. How do I then update that later when they check off additional interests. The insert tries to insert the original ones as well as the new ones. This is a violation of the Primary key and the statement is terminated.
Is there a way to skip some or do I need to run a delete first and remove the existing interests for that client and then do a new insert? When the page opens the checkboxlist is populated with the previous interests that were inserted for the client. The user can then check additional interests for the client and then click a button to do the insert.

I have a parameter for a method, that should be a string and I can't come up with how to <% *.ClientID %> to the thing as a variable like that. Since its a variable i can't wrap it in quotes since it will be taken literally and when I use the parameter like a variable (as you're supposed to) i get an ASP error saying it doesn't exist in the context (reading it literally).Code Sample
function next(currentControl, maxLength, nextControl) {
if (document.getElementById( currentControl<%=.ClientID %>).value.length >= maxLength) {
document.getElementById( nextControl<%=.ClientID %>).focus();

I have written below code to check for blank value in my textbox but its generating compilation Error.
my code in javascript:
function checkTextboxNotFilled(txtbox) {
var txtb = document.getElementById("<%= " + txtbox + ".ClientID %>");
if (GetFormattedString(txtb.value) == "") {
return true ;
}
else {
return false ;
}
}
error:
'string' does not contain a definition for 'ClientID' and no extension method 'ClientID' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)
I am calling it like this : checkTextboxNotFilled("MytextboxName")

I'm having a problem with <%= obj.ClientID %> expansion, in a .ascx user control.
I have a .js file, containing a javascript function:
function doSomething(objectId)
{
...
}
I have a .ascx file, with some html elements, and in one element's onclick= I want to call doSomething(), passing the ID of an element in that .ascx file, where the passed ID is of an element other than the one being clicked on, so I can't use "this.".
Maybe it'd be clearer with an example.
This works:
<script type="text/javascript">
function redirect()
{
doSomething('<%= top.ClientID %>');
}
</script>
<div id="top" runat="server">
<img src="..." alt="..." onclick="redirect();"/>
</div>
But this does not:
<div id="top" runat="server">
<img src="..." alt="..." onclick="doSomething('<%= top.ClientID %>');"/>
</div>
When I look at the source, I see that the <%=%> substitution has not happened, instead of "doSomething('ctl00_myControl_top');" I get "doSomething('<%=top.ClientID %>');"
For some reason, the script expansion happens in the former case, but not in the latter. The work-around, of course, is not acceptable because it will break if I include multiple copies of the control on a page - only one instance's "redirect()" function will be accessible.

function verifyEmail() {
var pageUrl = '<%=ResolveUrl("~/UserInterface/StaffPortal/StaffRegister.aspx")%>'
var verifyEmail = '{verifyEmail:"' + $('#<%=Text_email.ClientID%>').val() + '"}';
}
Above function is a little part of whole actual function where I'm using json to store data of textbox in variable and pass as a parameter in query.
as seen in above funtion I'm using
<%=Text_email.ClientID%>'
How can i pass this as parameter and use the same function for more than one textboxes?
function verifyEmail(idd) {
var pageUrl = '<%=ResolveUrl("~/UserInterface/StaffPortal/StaffRegister.aspx")%>'
var verifyEmail = '{verifyEmail:"' + $('#'+idd+'').val() + '"}';
}
I've tried above code. I've called function using verifyEmail('<%=Text_email.ClientID%>'); but it is not working.
When I alert idd then it prompts <%=Text_email.ClientID%> but when i pass variable idd in $('#+idd+') it doesnt work?

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 like to know how to get the ClientID/UniqueID of a control inside a Detailsview controls EditItemTemplate element and when DetailsViews changing to Edit mode and DetailsView is inside a AJAX UpdatePanel. Without UpdatePanel, during PostBack I can get the ClientID's control, but now with an UpdatePanel.
[Code]....
As you see, the EditItemTemplate contains a Checkbox control. So i'm trying to get the ClientID of this checkbox when Detailsview is changing to the Edit mode. I need this value for handling Javascript.
Catching the events ChangingMode/ChangedMode doesn't work; chkbox is null:
[Code]....
Maybe i'm using the wrong event? Someone can give me a tip about this?

OnClientChange="<%# "toggle('" & lblVar02.ClientID & "');" %>"></uc:CriteriaType>

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.
