Hello,

To persist any changes within an editor control in a template, you need to access the control and save the value manually. You may use the below lines of code to find value on the control and save it manually across post back. Below lines of code implement this:

int i = this.WebDataGrid1.Rows.Count;
for (int j = 0; j < i; j++)
{
CheckBox chktest = (CheckBox)this.WebDataGrid1.Rows[j].Items[0].FindControl("chk");
if (chktest.Checked == true)
{
//Write you code to save value
}
}

I would suggest you to use “UnboundCheckBoxField” introduced in version NetAdvantage 2011.1. Review the sample from the link below that will give more details on storing unbound data:

Hope this helps.
