Converting some code to vb.net from c#

Question

I am converting some classes from C# to VB.NET and this line can't be converted properly. I tried few online converters but they don't seem to work.

this.mGrid.RowDataBound += new GridViewRowEventHandler(RowDataBoundHandler);

Converted VB.NET that does not work.

Me.mGrid.RowDataBound += New GridViewRowEventHandler(RowDataBoundHandler)

The following are the two errors I am getting from that. Can anyone help me out coz my brain is dead now.

Thanks,

Error 4 Delegate 'System.Web.UI.WebControls.GridViewRowEventHandler' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor. C:\My Projects\PMS\App_Code\GridViewHelper.vb 110 62 C:\My Projects\PMS\

Error 3 'Public Event RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event. C:\My Projects\PMS\App_Code\GridViewHelper.vb 110 9 C:\My Projects\PMS\

Answer 1

Try using AddHandler if you want to bind the event manually:

AddHandler Me.mGrid.RowDataBound, AddressOf RowDataBoundHandler

Or you can bind the event in the ASPX markup:

<asp:GridView ... RowDataBound="RowDataBoundHandler" runat="server" />

Or use Tim Schmelter's approach.

Answer 2

You don't need to register the event handler programmatically in VB.NET. You can either use the aspx markup to declare the event handler(OnRowDataBound = "RowDataBoundHandler") or use the Handles clause. You can even use one for multiple controls, separate them by commas.

Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs) _
    Handles GridView1.RowDataBound
End Sub

If you want to add it manually anyway, use AddHandler:

AddHandler Me.GridView1.RowDataBound, AddressOf RowDataBoundHandler

Answer 3

Use this instead, which is the VB way of doing this. VB uses AddHandler to identify the event, and the AddressOf points to the delegate.

AddHandler mGrid.RowDataBound, AddressOf RowDataBoundHandler
