This was working in previous versions of the RadControls for ASP.NET AJAX, but now with version 2012.3.1016.35 it does not. I have a grid with both grouping and paging enabled, and only the first page appears. If I remove the <telerik:GridGroupByExpression> tag from the grid then the other pages are accessible.

Am I doing something wrong or is this a bug in the otherwise excellent Telerik controls?

Thanks -
Brad Harris

Here is my markup:

<html>

<head>

<title>Grid Group & Page Test</title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server" />

<telerik:RadGrid

ID="RgDamageCases"

runat="server"

AllowAutomaticDeletes="false"

AllowAutomaticInserts="false"

AllowAutomaticUpdates="false"

AllowFilteringByColumn="true"

AllowMultiRowEdit="false"

AllowPaging="true"

AllowSorting="false"

AutoGenerateColumns="false"

GridLines="Horizontal"

PageSize="5"

OnNeedDataSource="RgDamageCases_NeedDataSource"

>

<MasterTableView DataKeyNames="Id" CommandItemDisplay="None">

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldAlias="State" FieldName="State" HeaderValueSeparator=": " />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="State" SortOrder="Ascending" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

<Columns>

<telerik:GridBoundColumn UniqueName="State" DataField="State" HeaderText="State" AllowFiltering="true" AllowSorting="true" DataType="System.String" Visible="true" />

<telerik:GridBoundColumn UniqueName="Name" DataField="Name" HeaderText="Name" AllowFiltering="false" AllowSorting="true" DataType="System.String" Visible="true" />

</Columns>

<PagerStyle AlwaysVisible="true" Position="TopAndBottom" Mode="NextPrevAndNumeric" Visible="true" />

</MasterTableView>

<GroupingSettings CaseSensitive="false" ShowUnGroupButton="true" />

</telerik:RadGrid>

</form>

</body>

</html>

And the codebehind:

Imports System.Collections.ObjectModel

Imports Telerik.Web.UI

Partial Class GridTest01Page

Inherits System.Web.UI.Page

Protected Sub RgDamageCases_NeedDataSource(ByVal source As Object, ByVal e As GridNeedDataSourceEventArgs)

Dim grid As RadGrid = CType(source, RadGrid)

Dim items As New Collection ( Of MyType )

items.Add ( New MyType ( 1, "001 Test", "AZ" ) )

items.Add ( New MyType ( 2, "002 Test", "AZ" ) )

items.Add ( New MyType ( 3, "003 Test", "AZ" ) )

items.Add ( New MyType ( 4, "004 Test", "AZ" ) )

items.Add ( New MyType ( 5, "005 Test", "AZ" ) )

items.Add ( New MyType ( 6, "006 Test", "AZ" ) )

items.Add ( New MyType ( 7, "007 Test", "AZ" ) )

items.Add ( New MyType ( 8, "008 Test", "AZ" ) )

items.Add ( New MyType ( 9, "009 Test", "AZ" ) )

items.Add ( New MyType ( 10, "010 Test", "AZ" ) )

items.Add ( New MyType ( 11, "011 Test", "AZ" ) )

grid.DataSource = items

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

' Nothing Here

End Sub

End Class

Public Class MyType

Private _Id As Integer

Private _Name As String

Private _State As String

Public Property Id As Integer

Get

Return _Id

End Get

Set(value As Integer)

_Id = value

End Set

End Property

Public Property Name As String

Get

Return _Name

End Get

Set(value As String)

_Name = value

End Set

End Property

Public Property State As String

Get

Return _State

End Get

Set(value As String)

_State = value

End Set

End Property

Public Sub New(ByVal id As Integer, ByVal name As String, ByVal state As String)

Me.Id = id

Me.Name = name

Me.State = state

End Sub

End Class

So the EnableLinqGrouping="false" did not work for me, but what did work was adding a selectfield

<GroupByExpressions>
<telerik:GridGroupByExpression>
<SelectFields>
<telerik:GridGroupByField FieldAlias="AccountId" FieldName="AccountId" />
</SelectFields>
<GroupByFields>
<telerik:GridGroupByField FieldName="AccountId" SortOrder="Descending" />
</GroupByFields>
</telerik:GridGroupByExpression>
</GroupByExpressions>
