[Solved] Item Index of new record

[Philip Senechal]

I have a fairly normal grid that I'm running with an OnItemCreated sub. The sub does some really basic things like assign shared calendars to the date pickers and add a "Select an Item" to the combo boxes.

The other thing I have it do is to check one of the fields in each record for a particular value. If that value is not in the table that feeds a combo, it adds it manually to the combo. This works great when editing existing records because I already have an Index for the grid item, however, when adding a new record, my routine errors because the Index hasn't been created yet. I need the Index to perform a query and check for a value.

So what I really need is a way to determine whether or not the index exists when someone clicks on Add a Record. If it doesn't exist, I will just bypass my routine.

Can you help me figure out a way to determine if the item index exists?

This is the line of code that errors:

Dim task_id As String = item.OwnerTableView.DataKeyValues(item.ItemIndex)("task_id").ToString()


Thanks.

Hi Philip Senechal,

On ItemCreated you can check if you are inserting or editng an item. And depending on that - pass or implement your routine. Try with the following code snippet for instance:

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        If e.Item.OwnerTableView.IsItemInserted Then
              'passyour routine
        Else
              'your routine here
        End If
    End If
End Sub

All the best,
