Detecting Footer Row vs Data row in a gridview
Hello,
I am trying to run validation controls using page pre-render in vb for a gridview where I have the insert in the footer of the gridview and updates in the individual rows. The Prerender will highlight the controls which have failed the validation.
My problem is that when the Page prerender fires, I cannot figure out how to get the controls depending on whether it is an insert from the footer, or an update from a regular row in the Gridview.
The insert from the footer works well, but the update from a Gridview row does not.
Also I have got a formview in the gridviews empty template which also works well.
Here is my code:
1 Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
2 If Page.IsPostBack Then
3 For Each valControl As BaseValidator In Page.Validators
4 If GridView1.Rows.Count > 0 Then
5
6 Dim badControl As WebControl = GridView1.FooterRow.FindControl(valControl.ControlToValidate)
7 If Not valControl.IsValid Then
8
9 badControl.BackColor = Drawing.Color.Yellow
10
11 Else
12
13 badControl.BackColor = Drawing.Color.White
14
15 End If
16
17
18
19 Else
20 Dim EmptyInsert As FormView = CType(GridView1.Controls(0).Controls(0).FindControl("Formview1"), FormView)
21 Dim badControl As WebControl = EmptyInsert.FindControl(valControl.ControlToValidate)
22
23 If Not valControl.IsValid Then
24
25 badControl.BackColor = Drawing.Color.Yellow
26
27 Else
28
29 badControl.BackColor = Drawing.Color.White
30
31 End If
32
33 End If
34 Next
35 End If
36 End SubAny help would be appreciated!

if (e.Row.RowType == DataControlRowType.Footer || e.Row.RowType == DataControlRowType.Header){

I'm not sure if I follow you exactly but, could you put some processing in your GridView RowDataBound event and check for the footer there?
Private Sub GridView1_RowDataBound(ByVal sender As Object, _ ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) _ Handles GridView1.RowDataBound If e.Row.RowType = DataControlRowType.Footer Then ' Put Processing Here End If End Sub
