Question

In C# when I programmatically need to get a specific control from a GridView, I insert in my RowDataBound event handler:

HyperLink hl = e.Row.Cells[n].Controls[0] as HyperLink;

How can I get the same result in VB? I tried:

Dim hl = CType(e.Row.Cells(n).Controls(0), HyperLink)

and

Dim hl as HyperLink = CType(e.Row.Cells(n).Controls(0), HyperLink)

but they do not work.

Error 6 Value of type ‘System.Web.UI.Control’ cannot be converted to ‘System.Web.UI.WebControls.HyperLink’.

Anybody know if that is possible?

Look at the TryCast() operator. It is the direct equivalent to C#’s as operator.

Dim hl As Hyperlink = TryCast(e.Row.Cells(n).Controls(0), HyperLink)
