Question : Hide submit button if datalist control is empty
I would like to hide a submit button if a DataList is empty. I don't really know the code. If you submit an answer please show me the code also. I have to do it in VB.Net. I googled and found the following code that I place in the code behind under the Page load event.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dv As DataList
dv = SqlDataSource3.[Select](Da
taSourceSe
lectArgume
nts.Empty)
'Change DataSource name
If dv.ToTable.Rows.Count = 0 Then
Button1.Visible = False
End If
What I am having a problem with is the To.Table. I get the following error. 'ToTable' is not a member of 'System.Web.UI.WebControls
.DataList'
. I tried to get smart and attempted to stick the button within the datalist itself but quickly found out that does not work. PLEASE HELP!
