How do I reference checkbox1 or checkbox2 that is in the EditItemTemplate at Serverside. It is gives error when I try to declare Checkbox1 or checkbox2. Error: CheckBox1 is not declared. When I checked the ID property of checkbox1 this is what I see DetailsView1.Field3SpecializationData.EditItemTemplate.Checkbox1 and I tried to use that but gave error too. Please Help. Thanks.

If checkbox1.checked = true then
'perform operation
Else
'message
End If

It gives error usingthe above code. What do I do. Below is my detailsView control that contains the checkbox.

<asp:DetailsView ID = DetailsView1 runat ="server" AutoGenerateRows="False" BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" DataKeyNames="Student_ID" DataSourceID="SqlDataSource1"> <Fields> <asp:BoundField DataField="Student_ID" HeaderText="Student ID" ReadOnly="True" SortExpression="Student_ID" />
<asp:BoundField DataField="Student_Name" SortExpression="Student_Name" /><asp:BoundField DataField="Date" SortExpression="Date" />
<asp:TemplateField <EditItemTemplate><asp:CheckBox ID="Checkbox1" runat="server" Checked='<%# Bind("Specialization_Data") %>'> Enabled="false" />
</EditItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("Specialization_General") %>'Enabled="false" /> </EditItemTemplate></asp:DetailsView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MSIS_POSConnectionString %>"
ProviderName="<%$ ConnectionStrings:MSIS_POSConnectionString.ProviderName %>"
SelectCommand="SELECT * FROM [StudentInformation] WHERE ([Student_ID] = ?)" UpdateCommand="UPDATE [StudentInformation] SET [Student_Name] = ?, [Specialization_Data] = ?, [Specialization_General] = ?, WHERE [Student_ID] = ?">

Thanks

You can't use checkbox1 (or 2) directly, you must use the FindControl method - to find it inside the DetailsView.

the following code is adapted from a sample on ASPNet101.com dealing with a GridView - it might not be exactly correct, but it's the general form of what you need - I just don't have time right at this moment to test it.

       Dim dgItem As DetailsViewRow
        Dim chkGView As System.Web.UI.WebControls.CheckBox
            For Each dgItem In DetailsView1 .Rows
                chkGView = dgItem.FindControl("checkbox1")
                if chkGView.Checked=true then
                  ' whatever
               else
                  ' whatever else
               end if
            Next

Thanks Augustwind, I tried the code the following way but it didn't respond. Onclick the Edit Link, there are two link that appear, the Cancel and Update link. Although the code didn't respond but I will like it to when the update Link is clicked. Please Help. Note: It didn't respond at all to either way. Thanks.

Sub DetailsView1_RowUpdate(ByVal sender As Object, ByVal e As DetailsViewUpdateEventArgs)
Dim dgItem As DetailsViewRow
Dim chkGView As System.Web.UI.WebControls.CheckBox
For Each dgItem In DetailsView1.Rows
chkGView = dgItem.FindControl("checkbox1")
If chkGView.Checked = True Then
' whatever
lblNext.Text = "Selected"
Else
' whatever else
End If
Next
End Sub

Actually, when the user clicks the Update button, there are 2 possible events :
onItemUpdating, before the actual update) and
onItemUpdated - after the update - -

so - I'll assume you mean after the update occurs.

Try changing the signature of your subroutine to use 'DetailsViewUpdatedEventArgs'

also - double check, in the DetailsView tag, that 'DetailsView1_RowUpdate' is referenced like:

OnItemUpdated="DetailsView1_RowUpdate"
