Hi,
I have a Telerik RadGrid with a GridTemplateColumn that contains a checkbox, as follows:
<telerik:GridTemplateColumn HeaderText="MINE" UniqueName="MyTemplateColumn">
<ItemTemplate>
<asp:CheckBox id="MyCheckBox" runat="server"></asp:CheckBox>
</ItemTemplate>
</telerik:GridTemplateColumn>
I want to set the box to be "checked" based on a value read from the database. I could handle the ItemDataBound event and read the database when each row is bound, but that results in n lookups. Instead, I want to handle DataBound, and then set all the values at once. So, in that method, I want code like this:
// read all values from database first, then...
foreach(var chkbox in MyRadGrid.MasterTableView.Columns.FindByUniqueName("MyTemplateColumn").FindControl("MyCheckBox")) {
chkbox.Checked = oneValue;
}
That doesn't work, because FindControl isn't a method of GridColumn, and it won't generate an iterable list of the checkboxes. What is the correct way to iterate through the checkboxes in the template column? Thanks!
