RadGrid Programmatic Column Creation Filter Problem

Hi All,

I am using RadGrid control and creating one grid column programmatically but the problem is that when I use filter of that column it gives me an error radgrid is neither a DataColumn nor a DataRelation for table. I can view that column but when I try to filter the records using the date filter then it produces an error.

Also, how can I set the index of that column as I want to set the position of that column as number three because before that I have two more columns edit and delete.

Any help would be greatly appreciated.

Thanks in advance.

<telerik:RadGrid ID="rgList" Width="100%" AllowFilteringByColumn="true" Skin="Metro"

CssClass="table table-bordered" AutoGenerateDeleteColumn="false" AutoGenerateEditColumn="false"

EnableEmbeddedBaseStylesheet="true" AllowSorting="True" AllowPaging="false" PageSize="10"

ShowHeader="true" runat="server" AutoGenerateColumns="true" ShowStatusBar="true">

<MasterTableView TableLayout="Auto" CommandItemDisplay="Top">

<CommandItemSettings ShowRefreshButton="false" ShowAddNewRecordButton="false" ShowExportToCsvButton="true"

ShowExportToExcelButton="true" />

</MasterTableView>

<GroupingSettings CaseSensitive="false" />

</telerik:RadGrid>

Protected Sub rgList_ColumnCreated(ByVal sender As Object, ByVal e As GridColumnCreatedEventArgs) Handles rgList.ColumnCreated

If e.Column.UniqueName = "AutoGeneratedDeleteColumn" Then 'auto generated delete column id

Dim gridButtonColumn As GridButtonColumn = e.Column

gridButtonColumn.ConfirmText = Constants.DELETE_CONFIRM_MESSAGE

ElseIf e.Column.UniqueName = Constants.EDIT Then

TryCast(e.Column, GridBoundColumn).AllowFiltering = False

TryCast(e.Column, GridBoundColumn).HeaderText = ""

ElseIf e.Column.UniqueName = Constants.DELETE Then 'hiding Delete column from database

e.Column.Visible = False

ElseIf e.Column.UniqueName.Contains("_") Then

Dim sColType As String = e.Column.UniqueName.Split("_")(1)

If sColType = "GridDateTimeColumn" Then

Dim _GridDateTimeColumn As New GridDateTimeColumn

_GridDateTimeColumn.DataField = e.Column.UniqueName

_GridDateTimeColumn.HeaderText = "Callback Date"

_GridDateTimeColumn.EnableRangeFiltering = True

_GridDateTimeColumn.AutoPostBackOnFilter = True

rgList.MasterTableView.Columns.Add(_GridDateTimeColumn)

End If

Else

e.Column.AutoPostBackOnFilter = True

e.Column.CurrentFilterFunction = GridKnownFunction.Contains 'setting filter for all other columns

End If

End Sub

Issue with HeaderTemplate Style and Multiple Transfer Listboxes

Hello,

I have a page (code below) that has a tabstrip on it. Each tab loads a RadWindow. Each window has a RadListBox in it configured to AllowTransfer="true". Everything was working fine until I tried to style the header template. Once I added the style, the header on the second ListBox incorrectly.

Has anyone experienced any issues related to the styling of the header template?
