callback error from a nested XmlHttpPanel

Hi,

I have a page with multi XmlhttpPanels, including a parent panel and a number of children panels which are placed inside an asp repeater. The error happens when run set_value() for any children panel. I have set the script manager to the standard asp script manager on the page, and the EnableClientScriptEvaluation is set to true in the parent panel. Not sure if xmlhttppanel supports nesting. All works fine if I remove the parent panel.

The below is the error screenshot and the code. Any help would be much appreciated.

<telerik:RadXmlHttpPanel runat="server" ID="pnlRoom" OnServiceRequest="pnlRoom_ServiceRequest"

EnableClientScriptEvaluation="true" LoadingPanelID="RadAjaxLoadingPanel1" RenderMode="Block">

<asp:Repeater runat="server" ID="rptGroups" OnItemDataBound="rptGroups_ItemDataBound"

ClientIDMode="AutoID">

<ItemTemplate>

<fieldset class="fieldsetBlock1">

<div class="fieldsetTitle">

<%# Eval("GROUP_NAME")%>

</div>

<telerik:RadXmlHttpPanel runat="server" ID="pnlGroup" OnServiceRequest="pnlGroup_ServiceRequest"

RenderMode="Block">

<asp:Repeater ID="rptItems" runat="server" EnableViewState="false" ClientIDMode="AutoID">

<HeaderTemplate>

<table width="574px" class="hor-minimalist-b">

<tbody>

</HeaderTemplate>

<ItemTemplate>

<tr>

<td style="padding: 12px 8px;">

<a href="javascript:;" onclick='<%# string.Format("openItem(this,{0},0);", Eval("JOB_ITEM_ID")) %>'

class="a-job-item">

<%# Eval("ItemSummary") %></a>

</td>

</tr>

</ItemTemplate>

<FooterTemplate>

</tbody> </table>

</FooterTemplate>

</asp:Repeater>

<div class="divAddNewLinkButton">

<a href="javascript:;" onclick='<%# string.Format("openItem(this,0,{0});", Eval("JOB_ITEM_GROUP_ID")) %>'>

<span>✚</span> New Item</a></div>

</telerik:RadXmlHttpPanel>

</fieldset>

</ItemTemplate>

<SeparatorTemplate>

<br />

</SeparatorTemplate>

</asp:Repeater>

</telerik:RadXmlHttpPanel>

EventArgs undefined

I have configured my RadGrid to call a client side function and call an AJAX script to insert records into my dB.
I am successful at calling my Client Side JS function by utilizing the <clientevents onrowclick=RowClick> event.

<ClientEvents OnRowClick="RowClick" /> *** This works but it is not my ideal solution

I would like to call this function by the execution of the onblur event from a textbox control.

I have tried the code below but I am not having any luck:
<telerik:GridTemplateColumn HeaderText="Qty" AllowFiltering="false" UniqueName="Column2">
<ItemTemplate>
<telerik:RadTextBox ID="qty" runat="server" AutoPostBack="True">
<ClientEvents OnBlur="function(sender,args){RowClick(sender,args)}" />
</telerik:RadTextBox>
</ItemTemplate>
</telerik:GridTemplateColumn>

However, when I execute the Onblur event I get this error:

JavaScript runtime error: Object doesn't support property or method 'get_id'

I assume that this is due to the fact that it doesn't know the ROW id when inside of the textbox?

Any help is appreciated!

PivotGrid ignoring values dragged and dropped into row fields

We have a pivotgrid that isn't working correctly. The data comes from a stored procedure that de-normalizes a bunch of data, so that users can do ad-hoc querying on the results. The table can run into several hundred thousand rows.

This used to work correctly, but recently (perhaps with the q2 2014 update?) we've noticed issues. Drag a column into the row columns group, wheel spins, eventually the original table returns with no column breakdown. Sometimes (not consistently) we can get it to work by right-clicking, selecting 'Move to COLUMN field', generate, then right-click and move to row field.

We were using Ajax on the grid, tried removing that with no change. We've tried deferring the layout update, no difference. It seems the columns that cause the issue are usually text columns, but there is no error thrown and nothing reported on screen, just no column breakdown.

The frustrating thing is this used to work, and neither code or data has changed. Here's the code used to generate the pivot. The data source is an objectdatasource, using a query running against SQL Server.

<telerik:RadPivotGrid ID="pivotData" runat="server" AggregatesLevel="-1" AggregatesPosition="Columns"
        DataSourceID="dsExpenditures"
        ShowColumnHeaderZone="False" ShowDataHeaderZone="False" ShowRowHeaderZone="False" EnableConfigurationPanel="true"
        Skin="Metro">
        <Fields>
            <telerik:PivotGridAggregateField Caption="Total Spend" DataField="TotalSpend" UniqueName="TotalSpend"
                DataFormatString="{0:n2}">
            </telerik:PivotGridAggregateField>
        </Fields>
        <ConfigurationPanelSettings LayoutType="OneByFour" Position="Left" DefaultDeferedLayoutUpdate="true">
        </ConfigurationPanelSettings>
    </telerik:RadPivotGrid>

Problem in exporting muliple headers not working

Hi,

I am using radgrid with multiple headers. The headers are added in run time like as below

Dim header As GridItem() = rdgrid1.MasterTableView.GetItems(GridItemType.Header)
' Get the current THead element
Dim head As GridTHead = CType(header(0).Parent.Controls(0).Parent, GridTHead)

Dim additionalHeaderItem As GridHeaderItem
head.Controls.Add(additionalHeaderItem)

The changes are displayed. But, while export the grid, its only exporting only one header with data. The newly added header item is not exported. Kinly any one help to resolve this issue

Thanks in Advance,

radhtmlchart navigator selectionhint text always white/blank

I'm having mostly success using the navigator, but my selection hint always looks white/blank. The area seems to change size if I change the DataFormatString, which would seem to indicate the text is there ( I have not looked at source or browser debugger to verify), but I can't find any information about changing this text color.

Any insight or help would be appreciated.

Thanks,

Paste Plain Text pop-up causes you to jump to the top of the page.

When I use the Paste Plain text pop-up (associated with the non IE browsers), Although the Paste Plain text popup will appear directly over the RadEditor, the browser will jump UP to the top of the page and you will need to scroll back down to where the RADeditor is loaded to continue editing. This only happens the first time when pasting into the Radeditor and only from the non IE browsers.

Its not apparent on pages that are not tall, or where the RadEditor is at the top of the page. But in instances where the RadEditor appears low on the page it's quite annoying. Is there anything that can be done to prevent this jump?
