raise a bubble event.

[Lucifer]

Hi

I am trying to raise a bubble event.

I have a dropdownlist and a datalist in a datalist.

I want to use the postback from the dropdownlist to rebind the nested
datalist. But i need the event to be a datalist Command so i have
access to e.item for the main datalist

the aspx code

<asp:datalist id=PostageGroups
OnSelectedIndexChanged="ddlGroupStatus_SelectedInd exChanged"
AutoPostBack="True" ' etc...
<ItemTemplate>
'my dropdown for picking the status
'of the items to be listed in
<asp:dropdownlist id=ItemStatus ...
</asp:dropdownlist>
'nested datalist
<asp:datalist id=PostageItems
'some more code...
</asp:datalist:asp>
</ItemTemplate>
</asp:datalist>

i am trying to catch the datalist PostageGroups postback for the
dropdownlist ItemStatus so i can rebind the rested datalist

the aspx.vb code:

Public Event Command As
System.Web.UI.WebControls.CommandEventHandler

Protected Overridable Sub OnCommand(ByVal e As
System.Web.UI.WebControls.CommandEventArgs, ByVal source As Object)

RaiseEvent Command(source, e)

RaiseBubbleEvent(source, e)

End Sub

Public Sub ddlGroupStatus_SelectedIndexChanged(ByVal sender As
Object, ByVal e As System.EventArgs)

OnCommand(New
System.Web.UI.WebControls.CommandEventArgs("DropDo wn", CType(sender,
DropDownList).SelectedValue), CType(sender, DropDownList))

End Sub

Private Sub PostageTypes_ItemCommand(ByVal source As Object,
ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs ) Handles
PostageTypes.ItemCommand

If e.CommandName = "DropDown" Then

Dim GroupID As Integer =
CType(CType(e.Item.FindControl("lblDeliveryGroupID "), Label).Text,
Integer)
Dim Status As Boolean =
CBool(CType(e.Item.FindControl("ddlGroupStatus"),
DropDownList).SelectedValue)
Dim myPostage As New Ecom_PostageDB

With CType(PostageTypes.FindControl("PostageList"),
DataList)
..SelectedIndex = -1
..DataSource =
myPostage.GetPostageItemsByStatusAndGroup(Status, GroupID)
..DataBind()
End With

End If
