In gridview, updatepanel is not working

html code

<asp:GridView ID="gridprodlist" runat="server" AutoGenerateColumns="False" EmptyDataText="No record" Width="100%">
<Columns>
<asp:TemplateField HeaderText="Edit&lt;br/&gt;Delete&lt;br/&gt;Disable">
<ItemTemplate>
<table cellpadding="0" cellspacing="0" border="0">
     <tr>
        <td valign="top">
         <asp:UpdatePanel ID="UpdatePanel100" runat="server">
            <ContentTemplate>
        <asp:CheckBox ID="chkdis" runat="server" AutoPostBack="True" OnCheckedChanged="chkdis_CheckedChanged" ValidationGroup='<%# Eval("pid") %>' Text="Disable" />
            </ContentTemplate>
          </asp:UpdatePanel>
         </td>
    </tr>
</table>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />

.cs code

protected void chkdis_CheckedChanged(object sender, EventArgs e)
{
    CheckBox chkdis = (CheckBox)sender;
    int id = Convert.ToInt32(((CheckBox)sender).ValidationGroup);

    if (chkdis.Checked == true)

Move UpdatePanel to out of the GridView, and wrap the GridView in the UpdatePanel. If you still need postback on some controls then use, just before the closing tag of UpdatePanel.

<Triggers> 
<PostBackTriggers ControlId="YourControlId"/>
<Triggers>
</asp:UpdatePanel>

Try to register this CheckBox as async-postback control from codebehind:

protected void Page_Init(Object sender, EventArgs e)
{
     gridprodlist.DataBound += GridprodList_DataBound;
}  

private void GridprodList_DataBound(Object sender, EventArgs e)
{
    ScriptManager sm = ScriptManager.GetCurrent(Page);
    foreach(GridViewRow row in gridprodlist.Rows)
    {
        CheckBox chkdis = (CheckBox) row.FindControl("chkdis");
        sm.RegisterAsyncPostBackControl(chkdis);
    }
}

its working for first time only but on second time again my page gets refresh

Then try to use RowCreated which is triggered on every postback for every row:

ScriptManager sm = ScriptManager.GetCurrent(Page);

private void GridprodList_RowCreated(Object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        CheckBox chkdis = (CheckBox) e.Row.FindControl("chkdis");
        sm.RegisterAsyncPostBackControl(chkdis);
    }
}

It doesn't work like this because GridView is converted to table while being rendered. The update panel is not certainly being added to each row on being rendered. So, the best way is to put the gridview inside the updatepanel.

Try moving the UpdatePanel out of the GridView, and wrap the entire GridView in the UpdatePanel, and see if that makes a difference.
