How do I access elements of an ItemTemplate in a DataGrid?

Question

Hi I am trying to access my HyperLink1 that is in the ItemTemplate of my DataGrid. I am using VB.NET but it should be the same as C# i'm sure. Here's what I'm trying to do: HyperLink1.Attributes.Add(onclick window.open('popup.aspx'null'height=250 width=250status= no resizable= no scrollbars=no toolbar=nolocation=nomenubar=no ');) I have a link with ID=HyperLink1 but i get a message HyperLink1 is not declared. What am I doing wrong?

the thing is  that the controls are not strongly typed because they're not predefined two ways to access a control inside a Datagrid/Gridview.. 1) get a reference to the row then to his cells and from the cell's controls choose the appropriate one and parse it into the control type u want : ((HyperLink)DataGrid1.Rows[RowNumber].Cells[CellNumber].Controls[ControlNumber]).Text; another way to do it  is to get to the row you want then just try to get the control by it's id : ((HyperLink)DataGrid1.Rows[RowNumber].FindControl(HyperLink1)).Text;

Hi +First of all you should understand that You can able to access all the controls which are placed directly in the FORM only. +If a control is placed inside another control then you should first reference the Parent Control ( in your case it is Template Container) and from that container control you should reference the Child Controls ( HyperLink). I hope you got the idea. Cheers!!
