Hi Patrik below is what i have done and still not firing
Any ideas what 'm doing wrong?
My CheckBoxList in the DataList Below
-----------------------------------------
<asp:checkboxlist id="checkboxlist1" Runat="server" AutoPostBack="True"
OnSelectedIndexChanged="Check_Clicked"></asp:checkboxlist>
The itemDataBound I created below:-
--------------------------------------
Public Sub Item_Created(ByVal sender As Object, ByVal e As
DataListItemEventArgs) Handles DataList1.ItemDataBound
If e.Item.ItemType = ListItemType.Item Or _
e.Item.ItemType = ListItemType.AlternatingItem
Then
Dim cblGroups As CheckBoxList =
CType(e.Item.FindControl("checkboxlist1"), CheckBoxList)
'This is where i added the Handler
AddHandler cblGroups.SelectedIndexChanged, AddressOf Check_Clicked
Dim DS As DataSet
Dim MyConnection As SqlConnection
Dim MyCommand As SqlDataAdapter
MyConnection = New
SqlConnection("server=(local);database=pubs;integrated security=true;")
MyCommand = New SqlDataAdapter("select TOP 5 * from Authors",
MyConnection)
DS = New DataSet
MyCommand.Fill(DS, "Authors")
MyConnection.Open()
If Not (cblGroups Is Nothing) Then
cblGroups.Visible = True
cblGroups.DataSource = DS
'cblGroups.DataMember = "Groups"
cblGroups.DataTextField = "au_lname"
cblGroups.DataValueField = "au_id"
cblGroups.DataBind()
End If
MyConnection.Dispose()
End If
End Sub
And here the event thats suppose to fire the CheckBoxList below
----------------------------------------------------------------
Sub Check_Clicked(ByVal sender As Object, ByVal e As EventArgs)
Dim i As Integer
For i = 0 To checkboxlist1.Items.Count - 1
If checkboxlist1.Items(i).Selected Then
Message.Text = Message.Text &
checkboxlist1.Items(i).Selected & "<br>"
Else
Message.Text = Message.Text & "false <br>"
End If
Next
End Sub

No,
My advice is to use the event on the checkboxlist, but to bind it
dynamicly in the ItemDataBound event.
Is it one checkbox list / item in the datalist?

Thx Patrick for the reply
But when the checkBoxList was out of the DataList i used
onSelectedIndexChanged in the CheckBoxList
like so :-
But your advice is that i should add the "onSelectedIndexChanged " to the
DataList instead of the CheckBoxList?
<asp:checkboxlist id="checkboxlist1" Runat="server" AutoPostBack="True"
onSelectedIndexChanged=""Check_Clicked"></asp:checkboxlist></td>
Sub Check_Clicked(ByVal sender As Object, ByVal e As EventArgs)
Dim i As Integer
For i = 0 To checkboxlist1.Items.Count - 1
If checkboxlist1.Items(i).Selected Then
Message.Text = Message.Text & checkboxlist1.Items(i).Selected & "<br>"
Else
Message.Text = Message.Text & "false <br>"
End If
Next
End Sub
in message
How about binding the datalist to the selectedindexchanged event
You can programaticly bind any event of a control to a method of your
choice (as long as that method has the correct signture)
In VB.NET I think you do it with the AddHandler keyword. So you could in
ItemDataBound write something like:
AddHandler cblGroups.SelectedIndexChanged, onSelectedIndexChanged
I'm a C# guy so I'm not 100% certain of the syntax but it would point
you in the right direction I think.

I'm binding a CheckBoxlist below in the ItemDataBound(the CheckBoxList
is in
a Datalist)
By doing "li.Selected = True" i can see all the checkBoxes are selected.
But what i want is to be able to get a Boolean value TRUE or FALSE when
a
checkBox is selected.
When the checkBoxList was out of the DataList i used
"OnSelectedIndexChanged" and it was returning what i wanted but if its
in a
Datalist
and 'm Binding the CheckBoxList in ItemBound how can i get to it?
Any ideas?
If Not (cblGroups Is Nothing) Then
cblGroups.Visible = True
cblGroups.DataSource = DS
cblGroups.DataTextField = "au_lname"
cblGroups.DataValueField = "au_id"
cblGroups.DataBind()
For Each li As ListItem In cblGroups.Items
' I get all the CheckBoxes selected by doing below
li.Selected = True
Next
End If
