Set control id in vb.net repeater to property of datatable

Question

I have a grid control in a VB.Net page and the item template is as follows

<ItemTemplate>
    <cc1:vprCheckBox runat="server" id="chkQLItem" Checked='<%# Eval("selected")%>' />
</ItemTemplate>

On postback the id for this control is

<_ctl0_maincontent_grdql__ctl10_chkqlitem>on</_ctl0_maincontent_grdql__ctl10_chkqlitem>

Is there a way I could set it to include an ID, such as

<cc1:vprCheckBox runat="server" id="chkQLItem_<%#Eval('QLKey')%>" Checked='<%# Eval("selected")%>' />

So the output would be chkQLItem_123

Answer 1

Try below:

<ItemTemplate>
    <cc1:vprCheckBox runat="server" id="chkQLItem_<%# ((RepeaterItem)Container).ItemIndex + 1%>"Checked='<%# Eval("selected")%>' />
</ItemTemplate>

You can tweak it as well as per your requirements. Hope this helps!
