You may have Button, DropDownList etc controls in a Repeater/DataList that generates an Event. From those event handlers how do you find other controls inside the Repeater/DataList, in case you need the values from other controls.

Here in this example below we have a button and a textbox inside a Repeater. The Button have an OnClick event. Inside that event handler we want to get the value from the TextBox.

<asp:repeater id=”rpt”……>
<ItemTemplate>
<asp:TextBox id=”txt” runat=”server” />
<asp:Button id=”btn” Text=”TEST” onclick=”btn_Click” runat=”server”/>
</ItemTemplate>
</asp:Repeater>

protected void btn_Click(object sender, System.EventArgs e)
{
Button btn=(Button)sender;
Repeater rpt=(Repeater)btn.Parent;
//now you can use this rpt to find any control inside it
//For example
TextBox txt=(TextBox)rpt.FindControl(“txt”);
string val=txt.Text;
}
