RadAjaxLoadingPanel ist noch shown using usercontrols...

OnClient Event firing on pageload

Hi
I'm having trouble implementing a RadComboBox. The thing I would like to do is to save a temporary state of which checkboxes that where checked when the dropdown list first was opened. The state should then be used to restore the checked checkboxes if the user click on a cancel button. To do this have I tried the following code.

<telerik:RadComboBox ID="RadComboBox1" Runat="server" CheckBoxes="true" EnableCheckAllItemsCheckBox="true" Localization-CheckAllString="Select all"

EmptyMessage="Select" AutoPostBack="false" LabelCssClass="MultipleChoiceLabels" DropDownCssClass="MultipleChoiceLabels"

OnClientItemChecked="SaveState('ucMCDFilterByIAI_RadComboBox1')">

</telerik:RadComboBox>

function SaveState(DropDownID) {

var combo = $find(DropDownID);

var state = new Array();

var items = combo.get_items();

var itemCount = items.get_count();

for (var counter = 0; counter < itemCount; counter++) {

var item = items.getItem(counter);

}

The problem I'm experience is that when the page loads, the SaveState method is called. This is not what was intended. Even worse is that $find(DropDownID) is returning null and therefore breaks the whole function. The function is working as it should if I hook up it to a button that is called after the page has loaded. Any suggestions on what whats wrong and what to do?

item Arguments not exposed in GridBatchEditingCommand?

These arguments seem to have some of the data I need specifically the COLUMN of the edit item in a batch edit but I can not get them to expose to extract the data? Is this by design? How else am I suppose to get the column name or index of an edited item in the batch edit mode??

Hi,

I'm implementing the LoadOnDemand with WCF scenario and the WCF method is getting the context for the combo box as a null.
What might cause this error. below is my wcf operation contact implementation:

Add your operation implementation here

ViperService.ViperServiceClient viperServiceClient = new ViperService.ViperServiceClient();

return viperServiceClient.GetTraderGroupsLoadOnDemand(radComboContext);

}

<telerik:RadComboBox ID="rcmyCombo" runat="server" CheckBoxes="True" EmptyMessage="Choose" Width="300px" DataTextField="Name" DataValueField="Id"

EnableLoadOnDemand="true" ShowMoreResultsBox="true" EnableVirtualScrolling="true" ItemsPerRequest="10" >

Spell Check not Checking on Textbox

Hello,
I have a multi-line textbox with TinyMCE, and RadSpell button on a ModalPopupExtender.

The spell checker always comes up as "The spell check is complete!"  No errors are found.

I'm using .Net 4.0.
Here's the code:<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
<div id="divPopUPAdd"  class="contents" runat="server" align="center">
<ajaxToolkit:ModalPopupExtender ID="mpe1" runat="server" 
  BehaviorID="mpe1" TargetControlID="AddNewLinkBtn" PopupControlID="divPopUPAdd" 
  BackgroundCssClass="modalBackgroundClass" DropShadow="false">
  </ajaxToolkit:ModalPopupExtender>
<telerik:RadSpell ID="RadSpell1" runat="server" ControlToCheck="elm1" IsClientID="True" Skin="Silk" SupportedLanguages="en-US,English" Width="106px" Style="z-index: 1000"/>
 <asp:TextBox ID="elm1" name="elm1" runat="server" TextMode="MultiLine" ClientIDMode="Static"  Width="766px" Height="200px" />

 </div>  



The dictionary is in the App_Data/RadSpell folder

The bin has these files: Telerik.Web.Design.dll, Telerik.Web.UI.dll, Telerik.Web.UI.Dll.refresh, Telerik.Web.UI.Skins.dll & Telerik.Web.UI.xml 

The web.config file has:

 <handlers>

<add name="Telerik_Web_UI_DialogHandler_aspx" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" />

<add name="Telerik_Web_UI_SpellCheckHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" />

<add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />

</handlers> 



<httpHandlers>

  <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />

  <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" />

  <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />      

</httpHandlers>



Any ideas?

Grid AJAX error: PageRequestManagerParserErrorException

We just went through a pretty large codebase migration, and biggest issue we're having is with our RadGrid's AJAX (paging, dragging and dropping cells, etc.). Any attempt by the grid to use AJAX results in this error:

Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html P'.

Now, I know there's a vast array of reasons for this error to appear, but after trying dozens of fixes I'm hoping to get some assistance narrowing it down to the right one. It seems to me that the error is related to the fact that the server is responding to the AJAX POST request with the entire page (beginning with the DOCTYPE declaration you see above), instead of properly responding with just the grid's updated HTML. Is there any obvious reason for this to occur? Are we missing some sort of configuration option that makes sure the AJAX response only contains the updated HTML that's needed?

Thanks, any assistance would be greatly appreciated.
