Hello

I am using radgrid 5.1.2. I am binding the grid to a List(of Pair) objects. Here is the code to bind the grid

 

Dim stockList As List(Of Pair) = CType(Session("StockList"), List(Of Pair))

 

stockList.Insert(0,

 

 

 

 

New Pair(stockCode, stockType))

 

dgStock.DataSource = stockList

dgStock.DataBind()

I have checked that the stock list definitely has some items in it at this point. In the item data bound event however it is saying the data item is not set to an instance of an object. Here is the code

 

 

 

 

 

 

Protected Sub dgStock_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.WebControls.GridItemEventArgs) Handles dgStock.ItemDataBound

 

 

 

 

 

 

If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then

 

 

 

 

 

 

 Throw New Exception(e.Item.DataItem Is Nothing) <====says TRUE

 

 

 

 

 

 

 

 

 

 

 

 


At this point the dataItem object is nothing. I don't understand why this is. I tried the same thing using an array of string and the data item was still nothing.


Please can you helpme fix this
thanks

Hi andieje,

Generally ListItemType.Item and ListItemType.AlternatingItem are applicable only for MS list controls not for RadGrid. To achieve your goal you should use:

If TypeOf e.Item Is GridDataItem Then
