LinkButton OnClientClick code help, please.

How do i programmatically (in the codebehind) add OnClientClick="aspnetForm.target ='_blank';" to a LinkButton (lbnCtrlTitleChange_ctrl)?

I want the LinkButton to open a new window/tab but only if a textbox has got text in it.

I have the following code but it doesn't seem to be working.

Protected Sub lbnCtrlTitleChange_ctrl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbnCtrlTitleChange_ctrl.Click
        If txtControlID_ctrl.Text <> "" Then
            lbnCtrlTitleChange_ctrl.Attributes.Add("OnClientClick", "aspnetForm.target ='_blank';")
            Response.Redirect("~/ControlChange.aspx?CtrlID=" & txtControlID_ctrl.Text)
        End If
    End Sub

Is the code completely wrong, or just the wrong way to go about it? Please advise.

Thanks

lbnCtrlTitleChange_ctrl.Attributes.Add("OnClick", "aspnetForm.target ='_blank';")

onclientclick is asp.net property...you need to use onclick javascript to define client event...

thanks,

Rather than doing that on server side, you should check the textbox value at client side

<asp:LinkButton OnClientClick="return fooFunction()" ..

Javascript fooFunction actually check the textbox value , if that is not null then open new window using "window.open"...

and return false.

BTW, I dont see use of linkbutton, you can go with hyperlink control if you dont want postback.
