Hi Guys,
I haven't had the need to use much javascript...so please forgive my ignorance.
Im trying to write some client-side validation code.
The premise is that each listbox item hold a delimited value that contains a ProductId and other ProductIds it cannot coexist with.
For example value=1,4,6,8. This is intrepreted that the ProductId of this item =1 and it cannot be added to any list box which already has Products 4,6 or 8 in it.
I have successfully done this server side with the following code and I am trying to reproduce client-side with javascript. Any help would be appreciated.
Private
Sub
RadListBoxDestination_Transferring(sender
As
Object
, e
As
Telerik.Web.UI.RadListBoxTransferringEventArgs)
Handles
RadListBoxDestination.Transferring
Dim
aryNoCoExist
As
Array
Dim
i
As
Integer
Dim
Product
As
Integer
Dim
Cancel
As
Boolean
=
False
Dim
BoxItem
As
Telerik.Web.UI.RadListBoxItem
Dim
NoCoExist
As
String
=
""
Me
.ErrorLabel.Text =
""
If
RadListBoxDestination.Items.Count > 0
Then
Product = GetProductId(e.Items(0).Value)
'GetProductId returns the first delimited string item
For
Each
BoxItem
In
RadListBoxDestination.Items
If
Len(NoCoExist)
Then
NoCoExist = NoCoExist &
","
& GetNoCoExist(BoxItem.Value)
'GetNoCoExist returns the remaining delimited string minus the first item
Else
NoCoExist = GetNoCoExist(BoxItem.Value)
End
If
Next
aryNoCoExist = Split(NoCoExist,
","
)
For
i = 0
To
aryNoCoExist.GetUpperBound(0)
If
Product = aryNoCoExist(i)
Then
Cancel =
True
Me
.ErrorLabel.Text =
"Product Not Compatible with Existing Selections"
End
If
Next
e.Cancel = Cancel
End
If
End
Sub
My Listbox Definition:
