I'm trying to do a validation for checkboxlist on a server side as all java approaches didn't work. However, probably due to the checklistbox is inside a listview the FindControl is empty. how to find a control inside a listview on a button click event when the button is outside of the listview.
<asp:CustomValidator
ID="rfchblAnswers"
runat="server"
ErrorMessage="* Please, select at least a one checkbox."
OnServerValidate="cblCustomValidator"
EnableClientScript="false"
ValidationGroup="EnterData"
Display=
"Dynamic" />
Public
Sub cblCustomValidator(ByVal objSource
As Object,
ByVal objArgs As ServerValidateEventArgs)
Dim chblAnswers As CheckBoxList = _
CType(lv_qstns.FindControl("chblAnswers"), CheckBoxList)
If CType(lv_qstns.FindControl("chblAnswers"), CheckBoxList)
IsNot Nothing
Then 'it's not working here as it cannot find the control inside a listview
Dim boolFlag As
Boolean = False
For Each li
As ListItem In chblAnswers.Items
If li.Selected Then
boolFlag = True
End If
Next
If boolFlag Then
objArgs.IsValid = True
Else
objArgs.IsValid = False
End If
End If
End Sub

I want to use CustomValidator for CheckBoxList web control. I tried the code found on:[URL]
But it is not working for me. Nothing happens. No error.

But it doesn't execute client side CheckItem2 method.
I have a rather short (~30 item) CheckboxList control and when it changes, I need to know which Checkbox changed.
I've got the CheckboxList set to AutoPostBack so I know only one Checkbox changed, but I don't know how to detect which one.
Unfortunately, the SelectedIndex property of the CheckboxList is useless. I'm sniffing around checking the ViewState, but I'm not sure if that'll work or how I go about that.
I am trying to save all checked items from a checkboxlist into one column in ms sql. I would like to comma seperate each checked item. Is there any example code?
