Re: Hide Button when DataView is empty

for Dataview use

ASP.NET Syntax (Toggle Plain Text)
If dataview.count = 0 then
button1.visible = False
else
button1.visible = True
End If
If dataview.count = 0 then
button1.visible = False
else
button1.visible = True
End If

or
for datatables use

ASP.NET Syntax (Toggle Plain Text)
If datatable.rows.count = 0 then 
button1.visible = False
else
button1.visible = True
End If
If datatable.rows.count = 0 then 
button1.visible = False
else
button1.visible = True
End If

Re: Hide Button when DataView is empty

Thanks for your reply ptaylor965, !!

Well, first of all, I made a mistake about the component, Its a gridview; second of all, on which event do I put these codes? consider that my gridview its binded by design with a objectdatasource, and I can't change that.

Thanks again!!

Re: Hide Button when DataView is empty

For DataGrids use

ASP.NET Syntax (Toggle Plain Text)
If datagrid.rows.count = 0 then 
button1.visible = False
else
button1.visible = True
End If
If datagrid.rows.count = 0 then 
button1.visible = False
else
button1.visible = True
End If

I would place this code on form_load and on any buttons or events that fill/refresh the datagrid
