Solution 1

You can use the ClientIDMode attribute to force the client ID of the control. If you don't want it to be changed to the auto generated name you may set it to ClientIDMode="Static".

I am using .Net 2 . ClientIDMode="Static" is works in .Net framework 4.

Solution 2

Set ClientIDMode[^] to Static.

Quote:
Static-> The ClientID value is set to the value of the ID property. If the control is a naming container, the control is used as the top of the hierarchy of naming containers for any controls that it contains.

Hi ThinkingPro,

As this is a feature of .NET4, so you can't replicate the same in .NET2.

Instead please describe what exactly you want to do with the control, so that I can help you to apply some workaround.

Thanks,
Tadit

Actually i am doing enhancement of an existing application which was previously designed without master page.Now condition is when i have added master page all of its control id changes and weather getting value of a control via javascript function it couldn't find.

You can find using the jQuery ends with selectors.

var txtNameBox = $("input[id$='txtName']");

This is called Attribute Ends With Selector [name$="value"][^].

As the ID is 'ctl00_ContentPlaceHolder1_txtName', which ends with txtName, so this will work.

Use this technique. :)

In that case i have to change all existing variable that will take much time,anyway thanks your prompt reply :)

Finally i have solved this by the below code.

protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
StringWriter Html = new StringWriter();
HtmlTextWriter Render = new HtmlTextWriter(Html);
base.Render(Render);
writer.Write(Html.ToString()
.Replace("name=\"ctl00_ContentPlaceHolder1_", "name=\"")
.Replace("id=\"ctl00_ContentPlaceHolder1_", "id=\""));
}
