How to determine which button was pressed

Question

User1466833786 posted

VS2008. I have the following buttons and code:

<td>

<asp:LinkButton ID="lbtnA" runat="server" Text="A" />

</td>

<td>

<asp:LinkButton ID="lbtnB" runat="server" Text="B" />

</td>

<td>

Protected Sub lbtnA_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnA.Click, lbtnB.Click

End Sub

Is there a way to determine which link button was clicked?

Thanks,

You could have two seperate subs...

Protected Sub lbtnA_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnA.Click
     'lbtnA clicked
     'execute some code
End Sub

Protected Sub lbtnB_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnB.Click
     'lbtnB clicked
     'execute some code
End Sub

cast the sender object to button and check the name.  I don't use vb.net but the following should do it

Dim test as Button

test = CType(sender, Button)

if test.Name...do whatever

Yep, something like this: 

    Protected Sub lbtnA_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnA.Click, lbtnB.Click

        Dim btn As LinkButton = CType(sender, LinkButton)

        If btn.ID = "lbtnA" Then
            ' Do stuff
        End If

        If btn.ID = "lbtnB" Then
            ' Do other stuff
        End If

    End Sub

Yes, there sure is... the sender As Object passes you a reference to the object that sent it here.

Dim buttonName as String = CType(sender, LinkButton).ID

this will tell you the name of the button.
