Can't reference a label and image in ItemTemplate of FormView

I have a FormView I'm trying to put a "status indicator" in the ItemTemplate to indicate whether the value in the databound field is a 1, 2 or 3. The label in the ItemTemplate displays the correct value, but I'm having troubel referencing the label, "Status", and the image, "Image1". With the (now commented out) code in the Snippet window I get an "Object not set to an instance of an object" error.

      <asp:RadioButtonList ID="radStatus" runat="server" RepeatDirection="Vertical"
                               RepeatLayout="Flow"
                               DataSourceID="SqlDataSource1"
                               DataTextField="Status"
                               DataValueField="keyApplicantID"
                               SelectedValue='<%# Bind("Status") %>'
                               AppendDataBoundItems="True"
                               >
      <asp:ListItem Value="0">None</asp:ListItem>
      <asp:ListItem Value="1">Complete</asp:ListItem>
      <asp:ListItem Value="2">Pending</asp:ListItem>
      <asp:ListItem Value="3">Ineligable</asp:ListItem>
</asp:RadioButtonList>

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        'If FormView1.CurrentMode = FormViewMode.ReadOnly Then
        '    Dim StatusLabel As Label = CType(FormView1.FindControl("Status"), Label)
        '    Dim StatusImage As Image = CType(FormView1.FindControl("Image1"), Image)
        '    If StatusLabel.Text = "1" Then
        '        StatusImage.ImageUrl = "~/images/StatusGreen.png"
        '    ElseIf StatusLabel.Text = "2" Then
        '        StatusImage.ImageUrl = "~/images/StatusYellow.png"
        '    ElseIf StatusLabel.Text = "3" Then
        '        StatusImage.ImageUrl = "~/images/StatusRed.png"
        '    Else
        '        StatusImage.ImageUrl = "~/images/blankImage.gif"
        '    End If
        'End If

Can you paste the code you have for your FormView? All I see is code for the RadioButtonList

nmarun

Why can't you just say:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        'If FormView1.CurrentMode = FormViewMode.ReadOnly Then
        '    If Status.Text = "1" Then
        '        Image1.ImageUrl = "~/images/StatusGreen.png"
        '    ElseIf Status.Text = "2" Then
        '        Image1.ImageUrl = "~/images/StatusYellow.png"
        '    ElseIf Status.Text = "3" Then
        '        Image1.ImageUrl = "~/images/StatusRed.png"
        '    Else
        '        Image1.ImageUrl = "~/images/blankImage.gif"
        '    End If
        'End If
 End Sub

aibusinesssol...,
Um, okay, but the RadioButtonList is really the only relevant piece. It's between a <td> and </td> in the ItemTemplate, like I mentioned.

nmarun, because the label "Status" and the "Image1" are in the FormView ItemTemplate and so causes and error which tells me, "Name 'Status' is not declared" and "Name 'Image1' is not declared".

I've seen other posts which indicate that I have to use something like:
Dim StatusLabel As Label = CType(FormView1.FindControl("Status"), Label)
to gain access to those controls.

Have none of the "Experts" here ever referenced a control inside a FormView?

I'm just learning and finding myself in need of referencing labels and textboxes and such inside a FormView. I can't believe that this isn't something that's "common knowledge" among veteran programmers.

I searched for the answer before asking the question and it seems like this is either something so bizzar, you just don't do it, or the experts aren't willing to share this "secret". I'm sorry if I sound frustrated. I am.

aibusinesssolutions

I don't see how the RadioButtonList is relevant to your question at all. You want to figure out how to access Image1 and the Status Label.

In your code the Image1 tag is commented out with <%-- --%>, so you won't be able to access it at all.

I commented it out in my code because it doesn't work and my app in live and in use. I should have uncommented it before posting it, but I didn't. Sorry.

You're right, the RadioButtonList isn't very relevant, it's only setting the value of the label. The RadioButtonList is in the EditItemTemplate and the label, which I'm concerned with, is in the ItemTemplate. I thought the RadioButtonList code may show how I'm trying to use the label.

It looks promising, but I got this:

the FormView1_DataBound function? Where would I find that? It's not in my codebehind.

aibusinesssolutions

You see the two drop downs at the top of the code behind editor?

Click the drop down on the left and select FormView1, then click the one on the right and select DataBound, it will create the function for you and wire it up.

David Megnin

ASKER

Okay, I added one:

Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.ReadOnly Then
Dim lbl As Label = FormView1.FindControl("Label1")
Dim img As Image = FormView1.FindControl("Image1")
Response.Write(lbl.Text)
Response.Write(img.ImageUrl)
End If
End Sub

I still get the same error, just on the new line:

Object reference not set to an instance of an object.

Do you have a Label1 in your <ItemTemplate>? I just used that as an example

David Megnin

ASKER

With this in my FormView:

                                    Status:
                              </td>
                              <td>
                                    <%--<asp:Label ID="Status" runat="server" Text='<%# Bind("Status") %>' CssClass="tab" />--%>
                                    <%--<asp:Image ID="Image1" runat="server" ImageUrl="~/images/arrow007.gif" />--%>
                                    <asp:Label ID="Status" runat="server" Text='<%# Eval("keyApplicantID") %>'></asp:Label>
                                    <asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("keyApplicantID") %>' />
                              </td>

And this in the codebehind:

Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.ReadOnly Then
Dim StatusLabel As Label = CType(FormView1.FindControl("Status"), Label)
Dim StatusImage As Image = CType(FormView1.FindControl("Image1"), Image)
If StatusLabel.Text = "1" Then
StatusImage.ImageUrl = "~/images/StatusGreen.png"
ElseIf StatusLabel.Text = "2" Then
StatusImage.ImageUrl = "~/images/StatusYellow.png"
ElseIf StatusLabel.Text = "3" Then
StatusImage.ImageUrl = "~/images/StatusRed.png"
Else
StatusImage.ImageUrl = "~/images/arrow007.gif"
End If
End If

I don't get an error, but the label show the DateKeyName instead of the value of the field. I think I need to change <%# Bind("keyApplicantID") %> back to <%# Bind("Status") %>

aibusinesssolutions

Yeah, change it to Eval("Status")

aibusinesssolutions

Bind() is two way data binding, you don't need that in the item template, so use Eval, which is read only data binding.

David Megnin

ASKER

That worked. I changed the <%# Bind("keyApplicantID") %> back to <%# Bind("Status") %>
and now my label shows the little colored Icons to represent the status. :-)

David Megnin

ASKER

Oh, yeah, I see. I wouldn't need two way binding in the ItemTemplate. I'll change that to Eval.

Dang, these GridView and FormView controls are tricking to work with. I'm sure they are still a lot easier than coding something like that before .Net!

David Megnin

ASKER

Thank you very much for your help this late at night!

aibusinesssolutions

Yes they are, way easier. The old standard would require 3 pages typically.

user_view.asp
user_edit.asp
user_insert.asp

You had to create objects like this
Set objRecordset = Server.CreateObject("ADODB.Recordset")

and then step through the recordsets
objRecordset.Open strSQL, DB_CONNECTIONSTRING, adOpenKeyset, adLockPessimistic, adCmdText
If Not objRecordset.EOF Then
objRecordset.MoveFirst

It was a mess compared to .NET ;)

David Megnin

ASKER

I feel bad complaining about what a pain in the @$$ the .Net FormView and GridViews are. But, I'm just learning, so they do have some frustrating "features" that I haven't learned to use properly yet. ;-)

Thank you again. Now I just need to get rid of that extra item in my radioButtonList due to the "AppendDataBoundItems='True' " I had to use to get it to work.
