 When you load your control, please add an ID on it ex:
TextBox txt = new TextBox();
txt.ID = "MyID";

Then on your script you can point to this txt.ClientID
Hope this help

Hi vrparekh,

You can use "ControlID.ClientID" like the following code in the javascript.

var txt=document.getElementById("<%=txt1.ClientID%>");

It will be ok.

What's the Diff between Web Form and Server Control?
I'm confused in my transition from ASP to .NET. We've got the HtmlSelect Control (a Server Control) and we've got ASP:DropDownList Control (a Web Form Control). Waaaaahhhh???? Quick, explain why we have two and when to use them, before my head explodes!!!! Basically, you are talking about the same thing, and just using different terms. Sorta like comparing an active-x control to a COM object - it's the same thing. Anyway, in the case above, there are times (most of the time) when you will use Microsofts "web form controls", which are like your standard HTML controls...

Javascript function seeing the server control's ClientId as an object???
Ok, here's the situation. It's a simple scenario of having a textbox and three radiobutton controls. The radio buttons are to select by what type of a search you would want to perform. Either a name, id, or social security number. So when you click on a radiobutton I have a javascript function that is going to put a string into the textbox to display the proper format for the search criteria. I'm adding the attribute to the server control on page init event as:id_button.Attributes.Add("onclick", String.Format("DisplaySearchFormatString({0},formatId)", textbox....

Web Form Server Controls Vs. HTML controls
Hi1. What is the difference between Web Form Server controls and HTML controls with runat="server" attribute.e.g. <input type="text" id="mytext" runat="server"> Vs. <asp:TextBox id="mytext" />2. Why we should not use the normal HTML control instead of Server Controls since HTML controls are rendered on client side the performance in using them will be much better that using Web form server controls. Pls. can somebody explain this.- Anand one thing i know. there are much more options for the web controls. and web controls are easier to use than the http controls. for example, you wouldn't want to use html table(or even webcontrol table) if datagrid/datalist/repeater can be used. i don't think rendering performance would make a big difference, the number of controls on a page is very limited.  anandc wrote: Hi1.
