Hello guys,
I'm stuck in this little trouble. Please help me. I have a GridView gvList. In this GridView, I want to use Ajax popupcontrol
which will pop up a treeview.

XML

<asp:GridView ID="gvList" runat="server" AutoGenerateColumns="false" OnRowDataBound="gvRowDataBound" AllowPaging="false" AlternatingRowStyle-CssClass="alt2" class="table_title" CssClass="table_title" RowStyle-CssClass="alt" Width="100%">
   
<Columns>
<asp:TemplateField HeaderText="Action By">
  <ItemTemplate>
   <asp:TextBox ID="txtActionBy" runat="server"></asp:TextBox>
    <ajaxToolkit:PopupControlExtender ID="ajaxActionBy" BehaviorID="actionByBehavior"  runat="server" TargetControlID="txtActionBy" PopupControlID="pnlTreeView" Position="Bottom">
 </ajaxToolkit:PopupControlExtender>

  <asp:Panel ID="pnlTreeView" BackColor="White" runat="server" Width="200px" ScrollBars="Auto" style="max-height:200px;display:none;">

  <asp:TreeView ID="trview" BackColor="White" runat="server" ShowCheckBoxes="All" ShowExpandCollapse="true"></asp:TreeView><br />

<asp:CheckBox ID="chkOther" runat="server" Text="Other" Enabled="false" />
   
<asp:TextBox ID="txtOther" runat="server" Enabled="false" Width="200px"></asp:TextBox>
   </asp:Panel>
                                    
   </ItemTemplate>
      </asp:TemplateField>
</Columns>
</asp:GridView>

At code behind, I have this:

C#

protected void gvRowDataBound(object sender, GridViewRowEventArgs e)
 {

if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox txtActionBy = (TextBox)findControl(e.Row, "txtActionBy");

txtActionBy.Attributes.Add("onfocus", "ShowPopup('" + ajaxActionBy + "')");
TreeViewDataBind();
}
}

My JavaScript is as follows:

C#

function ShowActionBy(popupId) {

    var popup = $find('actionByBehavior');
        if(popup!=null){
            popup.showPopup();
        }
        }

But my popup works only in first row of the gridview. what is the fact ? Please anyone help.

I have been used the same concept in my project. it looks similar to your requirement, have a look, it might helps.
Design:

ASP.NET

<columns>
                                <asp:boundfield datafield="TraineeId" headertext="TraineeId" xmlns:asp="#unknown" />
                                <asp:boundfield datafield="Subject" headertext="Subject" xmlns:asp="#unknown" />
                                <asp:templatefield itemstyle-width="40" itemstyle-horizontalalign="Right" xmlns:asp="#unknown">
                                    <itemtemplate>
                                        <asp:image id="Image1" runat="server" imageurl="~/Images/magnify.gif" />
                                        <ajax:popupcontrolextender id="PopupControlExtender1" runat="server" popupcontrolid="Panel1" xmlns:ajax="#unknown">
                                            TargetControlID="Image1" DynamicContextKey='<%# Eval("NotificationId") %>' DynamicControlID="Panel1"
                                            DynamicServiceMethod="GetDynamicContent" Position="Bottom">
                                        </ajax:popupcontrolextender>
                                    </itemtemplate>
                                </asp:templatefield>
                            </columns>

Code behind:

C#

[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
        public static string GetDynamicContent(string contextKey)
        {

            //string constr = "Server=TestServer;Database=SampleDatabase;uid=test;pwd=test;";
            //string query = "SELECT UnitPrice, UnitsInStock, Description FROM Products WHERE ProductID = " + contextKey; 


            SqlConnection SqlCon = new SqlConnection("Data Source=V_rrd2005;Initial Catalog=TrainingDemo;User ID=sa;Password=sa4vij;Asynchronous Processing=true");
            SqlCommand SqlCom = new SqlCommand();
            DataTable dataTable = null;

            dataTable = new DataTable();
            SqlCom.Connection = SqlCon;
            SqlCom.CommandText = "SELECT * FROM [Notifications] where NotificationId=" + contextKey + " ";
            SqlDataAdapter ad = new SqlDataAdapter(SqlCom);
            ad.Fill(dataTable);


            StringBuilder b = new StringBuilder();

            b.Append("<table style="background-color:#f3f3f3; border: #336699 3px solid; ");<br mode="hold" />            b.Append("width:350px; font-size:10pt; font-family:Verdana;" cellspacing="0" cellpadding="3">");

            b.Append("<tr><td colspan="4" style="background-color:#336699; color:white;">");
            b.Append("Product Details"); b.Append("</td></tr>");
            b.Append("<tr><td style="width:80px;">BatchId</td>");
            b.Append("<td style="width:80px;">TraineeId</td>");
            b.Append("<td style="width:80px;">Description</td>");
            b.Append("<td>Priority</td></tr>");

            b.Append("<tr>");
            b.Append("<td>" + dataTable.Rows[0]["BatchId"].ToString() + "</td>");
            b.Append("<td>" + dataTable.Rows[0]["TraineeId"].ToString() + "</td>");
            b.Append("<td>" + dataTable.Rows[0]["Description"].ToString() + "</td>");
            b.Append("<td>" + dataTable.Rows[0]["Priority"].ToString() + "</td>");

            b.Append("</tr>");

            b.Append("</table>");

            return b.ToString();

        }

<style type="text/css">

        {
            /*font-weight: bold;
            background-color: #006699;
            color: #ffffff;*/
            
            height: 25px;
            position: absolute;
            top: expression(Sys.UI.DomElement.getBounds(document.getElementById("panelContainer")).y-25);
        }
    </style>

Thanks for your time Sanjeev. I've solved this myself like follows:
I've added onrowcreated in gvList

C#

protected void gvRowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                AjaxControlToolkit.PopupControlExtender pce = (AjaxControlToolkit.PopupControlExtender)e.Row.FindControl("ajaxActionBy");

                // Set the BehaviorID
                string behaviorID = string.Concat("pce", e.Row.RowIndex);
                pce.BehaviorID = behaviorID;

                // Programmatically reference the Image control
                TextBox txtActionBy = (TextBox)e.Row.Cells[1].FindControl("txtActionBy");

                // Add the clie nt-side attributes (onmouseover & onmouseout)
                string onfocus = string.Format("$find('{0}').showPopup();", behaviorID);
                
                txtActionBy.Attributes.Add("onfocus", onfocus);
                
            }
        }
