gv_InfoAssetsByParams.DataSource = ArrayAssets.ToList()
gv_InfoAssetsByParams.DataBind()
but when ArrayAssets is empty I want to make the gridview empty. SO I do this,
If ArrayAssets.Length > 0 Then
gv_Info.DataSource = ArrayAssets.ToList()
gv_Info.DataBind()
Else
gv_Info.DataSource = ArrayAssets.ToList()
gv_Info.DataBind()
End If
But it still appears even if i assign Nothing to the data source. How do I make it empty with headers?

Answer 1

ASP has a property called ShowHeader when empty. (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.showheaderwhenempty.aspx)
Set ShowHeaderWhenEmpty="false", that should work.

After looking at your code, you are repeating the same thing in your IF statement.
I tried to replicate your problem on my end, and indeed if the datasource is empty the grid is not visible. I think you should look at the properties of your gridview and go from there. As well, I recommend using a repeater for more control of the visibility and layout when displaying data.
