Hi,

this is because you add the javascript at that first click. At the second click, the javascript is existing and therefore being executed. You have to add the script earlier (e.g. on binding). The easiest way though would be to add
that javascript to your markup.

Hope that helps

Forgot: In addition to that, you could run your script immediatly without using the onlick handler. Google for "asp.net javascript RegisterStartupScript" or write it to your response stream

this code will be excuted on first click. So, the onclick attribute for the button will affect only from the second time. So, You add onclick attribute for the Image button on Row data bound event like this..

C#

// on row data bound event

 if(e.Row.RowType == DataControlRowType.DataRow)
 {
      Image img = (Image)e.Row.FindControl("imgSMS");
      img.Attributes.Add("onclick","window.open('Admin/Default.aspx','_blank','toolbar=0,location=0,menubar=0,resizable=0,height=300,width=300');return false");
 
 }

hope it works..
