Empty Datalist: show message?

Classified in: ASP.NET — paomic at 11:36 am

If you have a ASP.NET datalist and you need to show a message when there are no items in the list, you can use a code like the following:

myDataGrid.DataSource = …;
myDataGrid.DataBind();

if(myDataGrid.Items.Count == 0)
{
myDataGrid.Visible = false;
someLabelWithAMessage.Visible = true;
}
else
{
myDataGrid.Visible = true;
someLabelWithAMessage.Visible = false;
}

This is for C#, for VB it wuold be something like:
myDataGrid.DataSource = …
myDataGrid.DataBind()

If myDataGrid.Items.Count = 0 then
‘There are no records
myDataGrid.Visible = False
someLabelWithAMessage.Visible = True
Else
myDataGrid.Visible = True
someLabelWithAMessage.Visible = False
End If

Happy coding!
