Hello Friends,

   I am  using Infragistics controls in my application first time, and i am facing the following issue.

What I am trying to implement is:

   I am using a WebDataGrid and i have kept a ImageButton inside a Template field in the grid. my requirement is onclick of the ImageButton i need to create a panel dynamically with some values and that i am implementing in Itemcommand event.

But the problem i am facing is on click of the Imagebutton the post back is happening which i dont want. Can anyone help me how to stop Postback.

Code in ItemCommand:

  protected void WebDataGrid1_ItemCommand(object sender, Infragistics.Web.UI.GridControls.HandleCommandEventArgs e)
        {
           

            string commandname = e.CommandName;
 
            if (commandname == "image")
            {
                pan.Visible = true;
                RowIndex = Convert.ToInt32(e.CommandArgument);
                PromotionID = WebDataGrid1.Rows[RowIndex].Items[0].Value.ToString();
                Status = WebDataGrid1.Rows[RowIndex].Items[2].Value.ToString();
                
                pan.Visible = true;
                pan.Style.Add(HtmlTextWriterStyle.Width, "100px");
                pan.Style.Add(HtmlTextWriterStyle.Height, "100px");
                pan.Style.Add(HtmlTextWriterStyle.BorderColor, "black");
                pan.Style.Add(HtmlTextWriterStyle.BorderWidth, "1px");
                pan.Style.Add(HtmlTextWriterStyle.BorderStyle, "Solid");
                pan.Style.Add(HtmlTextWriterStyle.Top, ( 150+(RowIndex*20)+"px").ToString());
                pan.Style.Add(HtmlTextWriterStyle.Left, "500px");
                pan.Style.Add(HtmlTextWriterStyle.ZIndex, "102px");
                pan.Style.Add(HtmlTextWriterStyle.Position, "absolute");
                pan.Style.Add(HtmlTextWriterStyle.BackgroundColor, "White");
 
                foreach (KeyValuePair<string,List<string>>  pair   in dic)
                {
                    if (Status == pair.Key)
                    {
                        for (int i = 0; i < pair.Value.Count; i++)
                        {
                            LinkButton lnkbtn = new LinkButton();
 
                            lnkbtn.Text = pair.Value[i].ToString() +"</br>";
                            lnkbtn.ID = "LinkButton" +( RowIndex + 1);
                            lnkbtn.PostBackUrl="About.aspx? PromotionID=" +PromotionID;
                            pan.Controls.Add(lnkbtn);
                        }
                    }
                }
                Form.Controls.Add(pan);
             //   RaiseBubbleEvent(this, e);  // not working
           //     e.Handled = true;
            
 }
