Question

I have the following snippet in VB.Net (web application):

Dim lnkTemp as HyperLink = dvFileInfo.FindControl("lnkPlan")

dfFileInfo is a DetailsView control from System.Web.UI.WebControls

When I try to convert this to C# like this:

HyperLink lnkTemp = dvFileInfo.FindControl("lnkPlan");

I get an error after the “=” that states:

Cannot implicitly convert type ‘System.Web.UI.Control’ to System.Web.UI.WebControls.HyperLink’. An explicit conversion exists (are you missing a cast?)

What do I need to do to correct this issue?

Thanks!

Answer 1

Just cast it:

HyperLink lnkTemp = (HyperLink)dvFileInfo.FindControl("lnkPlan");

Or be a little safer:

HyperLink lnkTemp = dvFileInfo.FindControl("lnkPlan") as HyperLink;
// check for lnkTemp == null

The writer of the VB code should probably have been doing the following for clarity:

Dim lnkTemp As HyperLink = DirectCast(dvFileInfo.FindControl("lnkPlan"), HyperLink)
