problems retrieving text from textbox on datagrid when edit/update

[davidrobin]

I have a datagird with the edit feature enabled.
When the update command is fired the text property of the textbox in the datagrid column is empty though there is text there.
I have included the EditCommand and UpdateCommand subs for you to see.
In UpdateCommand strText is always = ""

Please Help
Private Sub dgrSelected_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgrSelected.EditCommand

dgrSelected.EditItemIndex = e.Item.ItemIndex
dgrSelected.DataSource = m_dvwData
dgrSelected.DataBind()
End Sub

Private Sub dgrSelected_UpdateCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgrSelected.UpdateCommand

Dim strText As String
Dim txtText As New TextBox '= CType(e.Item.Cells(4).Controls(0), TextBox)
txttext = CType(e.Item.Cells(4).Controls(0), TextBox)
strText = txtText.Text

dgrSelected.EditItemIndex = -1
dgrSelected.DataSource = m_dvwData
dgrSelected.DataBind()
End Sub

I have found that sometimes a literalcontrol is at index 0, and the textbox is at index one. The better way would be something like this though:

txttext = CType(e.Item.Cells(4).FindControl("YourTextBoxName"))
or
txttext = CType(e.Item.Cells(4).Controls.FindControl("YourTextBoxName"))

Not sure on the exact syntax there, but I think it is one of those. This will have the added effect of not needing to worry if the indexes ever change, so long as the name never changes.

I don't know the name of the textbox because it is in a boundcolumn that changes into a textbox when the EditCommand event fires.
