Showing and hiding filters on button press from programmatically created RadGrid

I am creating a RadGrid programmatically in VB.Net and have set the AllowFilteringByColumn = True and setup a CommandItemTemplate that contains a RadButton.

You can see the rendered grid in the attached Grid.png and the error I am getting in the Telerik.Web.UI.WebResource.axd. It looks like a problem with creating multiple filter items. Error description - "description "Sys.WebForms.PageRequestManagerServerErrorException: Multiple controls with the same ID 'FilterTextBox_CustomerNum' were found. FindControl requires that controls have unique IDs.""

CustomerNum is the first column in the grid

Building the grid

Private Sub SetFilters(ByVal grid As RadGrid)

grid.MasterTableView.AllowFilteringByColumn = gridConfiguration.EnableHeaderFiltering

If gridConfiguration.EnableHeaderFiltering Then

grid.MasterTableView.CommandItemTemplate = New RadGridCommandItemFilterTemplate

End If

End Sub

CommandItemTemplate

Friend Class RadGridCommandItemFilterTemplate

Implements ITemplate

Public showHideFilter As RadButton

Public Sub New()

MyBase.New()

End Sub

Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn

showHideFilter = New RadButton With {.ID = "showHideFilter", .Text = "Show / Hide Filters",

.CommandName = "ShowHideFilters", .OnClientCheckedChanged = "showHideFilters()"}

container.Controls.Add(showHideFilter)

End Sub

End Class

Why PivotGrid shows "1" when no data?

I'm counting number of appearing of a datafield by:

<telerik:PivotGridAggregateField DataField="StatusText" Aggregate="Count" Caption="Counts" UniqueName="Counts" IsHidden="false">

</telerik:PivotGridAggregateField>

The problem appears when I run the pivotgrid, there's a field of (blank) keeps on coming up with a value of "1" unexpectedly. I can see one common point for all (blank) data, they seem to happen to any columns that has no data in it. For Instance, in January 1st. I have no data for that day and the grid gives a value "1" with statustext = (blank) as a substitution.

What property can I set to stop this? Below is my RadPivotGrid Settings. Thanks.

<telerik:RadPivotGrid ID="RadPivotGrid_DataView" runat="server" ConfigurationPanelSettings-DefaultDeferedLayoutUpdate="false" Height="100%" AggregatesPosition="Rows" AllowSorting="True" OnItemCommand="RadPivotGrid_DataView_ItemCommand" OnCellCreated="RadPivotGrid_DataView_CellCreated" DataSourceID="Sql_Contract_Details" EnableToolTips="True" EnableZoneContextMenu="True" EnableConfigurationPanel="True" OnFieldCreated="RadPivotGrid_DataView_FieldCreated" Skin="Metro" OnCellDataBound="RadPivotGrid_DataView_CellDataBound" Culture="en-GB" OnItemNeedCalculation="RadPivotGrid_DataView_ItemNeedCalculation" AllowPaging="True" PageSize="30">

<PagerStyle ChangePageSizeButtonToolTip="Change Page Size" PageSizeControlType="RadComboBox" AlwaysVisible="True" />

<Fields>...</Fields>

<ClientSettings EnableFieldsDragDrop="True">

<Scrolling AllowVerticalScroll="True"></Scrolling>

</ClientSettings>

RadGrid Multicolumn header context menu show/hide breaks filter row

Hi there,

When I click to show/hide a column from the context menu with a multicolumn header the whole grid gets out whack due to the filter row ending up on the same row as the column headers (see pictures of before (Normal.png) and after (one_column_removed.png)). Any ideas why this is happening?

Here is my grid code:


<ClientSettings AllowColumnsReorder="True" ReorderColumnsOnClient="True" EnableRowHoverStyle="True" AllowColumnHide="False">
	<Selecting AllowRowSelect="False" />
	<Resizing AllowColumnResize="True" AllowResizeToFit="True" ResizeGridOnColumnResize="False" />
	<Scrolling AllowScroll="True" UseStaticHeaders="True" />
	<ClientMessages DragToGroupOrReorder="Click the Header to Sort; Drag to Reorder; Right Click for Context Menu" />
</ClientSettings>

...

[Solved] Setting the SelectedDate property of the RadDatePicker disables the SelectedDateChanged event handler?

I have a RadDateTimePicker on a page of my C# DotNet 4.0 web app.
The idea is that every time the selected date changes, the event handler updates a text box.
This is intended to be an Ajax event, not a full page postback.
To this end, the controls are set up in the RadAjaxManager as follows:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" >
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="rdtDateTime">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="txtCount" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>

This works perfectly, unless in the page load event I set the SelectedDate property of the RadDateTimePicker.
If I do that the SelectedDateChanged event stops firing.

Suggestions?
