Gridview - check select parameter

[Tony WONG]

the gridview is filtered by a textbox

when the user inputs 2009-1782 in the textbox

then the gridview shows the record numbered 1782

String before hypen is irrelevant, then a button event is used to erase
"2009-" in the textbox
***********
If InStr(SearchNo.Text, "-") = True Then
SearchNo.Text = Right(SearchNo.Text, len(SearchNo)-5)
GridView1.DataBind()
End If
************

but page error, it seems select command fires before change of textbox

What's the best way to do validating select parameters for the gridview?

Thanks a lot.

Hi Tony,

I believe that the error is about type mismatch. First of all, InStr
returns integer and not boolean, change to

If InStr(SearchNo.Text, "-") > -1 Then

then change len(SearchNo)

to len(SearchNo.Text)

Hope this helps

Thanks a lot. Alexey

Glad it helps. It always useful to see what error message system
returns. In most cases a message tells exactly what the problem is. If
you have just "an application error" then set customErrors mode to Off
