First, take a button in a div tag as shown below.

XML

<div style="visibility:hidden">
<asp:Button id="btnSample" runat="server"/>
</div>

Now in the gridview we use the Commandfields to display the Edit,Update cancel button

XML

<asp:CommandField ButtonType="Button" ShowEditButton="true" ShowCancelButton="true"
                       EditText="Select" UpdateText="Update" CancelText="Cancel" HeaderText="Confirm">
                       <HeaderStyle Font-Size="Smaller" Font-Bold="true" HorizontalAlign="Left" Width="45%" />
                       <ItemStyle Font-Size="Smaller" HorizontalAlign="Left" Width="45%" />
                   </asp:CommandField>

Next, we assign the targetcontrolid of MPE equal to the button hidden in div tag.

XML

<ajax:ModalPopupExtender ID="MPEAward" runat="server" TargetControlID="btnSample" PopupControlID="pnlSave"
    BackgroundCssClass="modalBackground" DropShadow="true" CancelControlID="btnCancel"
    Drag="true">
</ajax:ModalPopupExtender>

In the code behind

In gridview rowdatabound, we find the Update button present in gridview and invoke a javascript ShowPopUp()

if (e.Row.RowType == DataControlRowType.DataRow)
           {
               if ((e.Row.RowState & DataControlRowState.Edit) > 0)
               {
                   Button btnUpdate = (Button)e.Row.Cells[6].Controls[0];
 
                   btnUpdate.OnClientClick = "return ShowPopup();";
 

               }
           }

In Javascript,

C#

function ShowPopup() {

        $('#<%= btnSample.ClientID %>').click();
        return false;
    }

Finally, the page needs to return false in the javascript so as to make the modalpopup present on the page.

Solution
According to the codes in above article, your ModalPopUp should be like...

ASP.NET

<AjaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" 
                                runat="server"
                                TargetControlID="Button1"
                                PopupControlID="Panel1"
                                PopupDragHandleControlId="PopupHeader"
                                BackgroundCssClass="ModalPopupBG"
                                OkControlID="btnSend"
                                CancelControlId="btncancel"
                                Drag="true">
</AjaxToolkit:ModalPopupExtender>

Here there is no need to specify the LinkButton.

Attach an OnClick Event to LinkButton.

XML

<asp:LinkButton ID="popup" runat="server" Text="Click to Contact" OnClick="popup_Click"></asp:LinkButton>

Define that Event on Code Behind like...

C#

protected void popup_Click(object sender, EventArgs e)
{
    // Other Codes.

    // Show ModalPopUpExtender.
    ModalPopupExtender1.Show();
}
