Hi Yatin,

Re-write your code as below.

C#

protected void GrdRightDetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
   {
      System.Web.UI.WebControls.CheckBox chk = (System.Web.UI.WebControls.CheckBox)e.Row.FindControl("ChkStatus"); 
      string QryCount = "SELECT * FROM RightMaster WHERE UserID='" + Convert.ToInt32(HiddenField1.Value) + "' AND Status = 1";
      try
      {
         SqlConnection con = new SqlConnection(ConnString);
         SqlCommand cmd = new SqlCommand(con, QryCount);       
         DataSet ds = new DataSet();
         con.Open();
         SqlDataAdapter da = new SqlDataAdapter(cmd);
         da.Fill(ds);
         if (ds.Table[0].Rows.Count>0)
         {
            chk.Checked = true;
            //chk.Checked = Convert.ToBoolean(drv["Status"]); this line not required if you want to update checked box according to your select query
         }
      }
      Catch {}
    }
}

If you face any issue please let me know.
Hope this will help you.

It Select All the check-box. actually i have open one model popup box and inside that i bind grid view.
here is that :-
<asp:GridView ID="GrdRightDetails" runat="server" CssClass="mGrid"
AutoGenerateColumns="false" GridLines="Both" CaptionAlign="Top" CellPadding="2"
CellSpacing="2" onrowdatabound="GrdRightDetails_RowDataBound">
<columns>
<asp:TemplateField HeaderText="PageNo">
<itemtemplate>
<asp:Label ID="lblPageID" runat="server" Text='<%#Eval("ID") %>' >

<asp:TemplateField HeaderText="PageName">
<itemtemplate>
<asp:Label ID="lbldisplayname" runat="server" Text='<%#Eval("DisplayName") %>' >

<asp:TemplateField HeaderText="Status">
<itemtemplate>
<asp:CheckBox ID="ChkStatus" runat="server" />

This is because you are using same user id for each row. Which you are taking form hidden field, Put this hidden field as well into gridview and then check.

What value store i in that hiddenfiled which is inside my popup control??

Mohd. Mukhtar 22-Nov-12 1:46am

It should be user ID but the hidden field should be in gridview. And when you bind the gridview each rows data will have associated userid.

its already in gridview.
here is my full aspx page code:-

<asp:GridView ID="GrdUser" runat="server" DataKeyNames="UserID" CssClass="Grid" AutoGenerateColumns="false">
<columns>
<asp:BoundField DataField="EmployeeName" HeaderText="User Name" />
<asp:TemplateField HeaderText="Rights">
<itemtemplate>
<asp:ImageButton ID="imgbtn" ImageUrl="~/Images/icon2.jpg" runat="server" Width="15" Height="15" onclick="imgbtn_Click" ToolTip="Click To Show Rights" />

<PagerStyle CssClass="GridPager" />
<alternatingrowstyle cssclass="GridAltItem">
<PagerSettings PageButtonCount="5" />
<rowstyle cssclass="GridItem">
<HeaderStyle CssClass="GridHeader" />


<asp:Button ID="btnShowPopup" runat="server" style="display:none" />
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="btnShowPopup" PopupControlID="pnlpopup" CancelControlID="btnCancel" BackgroundCssClass="modalBackground">
<animations>
<onshown>
<fadein duration=".75" fps="20">

<asp:Panel ID="pnlpopup" runat="server" BackColor="White" Height="50%" Width="90%">
<table style="border:Solid 3px #888" cellpadding="0" cellspacing="0">

<asp:GridView ID="GrdRightDetails" runat="server" CssClass="mGrid"
