I have a GridView in my page :
There is no Text
as your data is stored in controls. You need to search for the control you want and pull the Text
out of.
Eg:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
string temp = row.Cells[4].FindControl('LabelGridViewBankName').Text;
LabelResult.Text = temp;
}
Optionally you could could key off the DataKey
property if you are using it and then use it to search your datasource for the value you want.
