Title: Textbox Events [asp.net]
Post by: Imperceptus on October 06, 2009, 01:42 PM

I have a grid view that I am casting data out of into a textbox.


   Protected Sub gvSpread_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvSpread.RowDataBound

        Select Case e.Row.RowType
            Case DataControlRowType.DataRow

                Dim txtTicker As TextBox = _
                    TryCast(e.Row.Cells(0).FindControl("TextBox1"), TextBox)

                txtTicker.Attributes.Add("onblur", "validate();")
                txtTicker.Attributes.Add("autocomplete", "off")
                txtTickers.Add(txtTicker.UniqueID)

                AddHandler txtTicker.TextChanged, AddressOf txtTicker_Changed

                Dim txtValue As TextBox = TryCast(e.Row.Cells(1).FindControl("TextBox2"), TextBox)
                txtValue.Text = FormatCurrency(txtValue.Text, 2)
                txtValue.Attributes.Add("onKeyUp", "totalfields();")

                AddHandler txtValue.TextChanged, AddressOf txtTicker_Changed
                ValueTotal += Val(txtValue.Text)

Is expecting the AddHandler statements to actually work a fantasy?

And actually, yes. Web forms controls don't really maintain state like you're trying for (you'd have to rebind the event every time the page was posted-back).
