How can I use an alert popup from my .vb codebehind file?

I just want a message or alert box to state this.

"The data set contains more than 35000 rows.  Please narrow your search criteria."

If you are doing it from a click event, when you test for dataset rows, if it is > 35000, do this:

string alertMsg = "The data set contains more than 35000 rows.  Please narrow your search criteria.";
string scriptMsg = "<script language='javascript'>alert('" + alertMsg + "');</script>"

Response.Write(scriptMsg);

An alternative to this, and this is how I usually handle this sort of thing, is to place a label control below the command button that causes the postback, but I set the Visible property to false on the label.  Then if certain conditions are met or excpetions are raised, I will put a message in the label.Text property and set the Visible property to true.  This causes the page to show the message in label without having to worry about JavaScript calls.

1.///////////////////////////////////////////////////////////////
//for different events
Me.Button1.Attributes.Add("onclick", _
                   "return confirm('Are you sure you want to delete?');")



2.///////////////////////////////////////////////////////////////
//to use javascript on events of body load and unload functions

//declare it as globel
Protected WithEvents bodytag As HtmlGenericControl

//now use these line where ever required
bodytag.Attributes.Add("onload", "window.open('popup.aspx',null,'height=250, width=250,status= no, resizable= no, scrollbars=no, toolbar=no,location=no,menubar=no ');")



3.////////////////////////////////////////////////////////////////
