    Get DataKey value on check box checked event in a GridView

    Here is the .aspx code for the following:-

      <asp:GridView ID="grdTest" runat="server" AutoGenerateColumns="False" DataKeyNames="ID">
        <Columns>
        <asp:TemplateField HeaderText="Is Released" >
         <ItemTemplate>
        <asp:CheckBox ID="chkReleased" runat="server" OnCheckedChanged="chkReleased&#95;CheckedChanged" AutoPostBack="true" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
    

    Write the following code on C# page.

     protected void chkReleased_CheckedChanged(object sender, EventArgs e)
        {
        CheckBox chkreleased = (CheckBox)sender;
        GridViewRow row = (GridViewRow)chkreleased.NamingContainer;
        string Id = grdTest.DataKeys[row.RowIndex].Value.ToString();
      }
