Hi
I have been upgrading an appication from Asp.Net to Asp.Net Ajax. But I'm having trouble making the ajax part working.
All I get is this error:
"Error: 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."

As soon as I add a Ajaxsetting programatically or through html I get the same error.

I have been stuck on this error some while now. I have browsed the forum for help, but cant seem to find a solution to my problem.

Adding a simple page that produces this error

Please help

Horizontal lines not aligned

Hi,

We are having problems with horizontal lines not being aligned in the Scheduler (see attached image not_aligned.png - note that the red areas in the image are appointments that have visible=false and a red background). The mark-up for our Scheduler is:

<telerik:RadScheduler runat="server" ID="CalendarScheduler" DayStartTime="06:00:00" Culture="da-DK" AllowEdit="False" AllowDelete="False" GroupBy="User" DayEndTime="20:00:00" TimeZoneOffset="02:00:00" DataKeyField="ID" Format="HH:mm" DataSubjectField="Subject" DataStartField="Start" DataEndField="End" InsertingInAdvancedForm="True" OverflowBehavior="Expand" ColumnWidth="50px" SelectedView="WeekView" ShowAllDayRow="False" ShowViewTabs="False" Height="414px" OnClientAppointmentInserting="OnClientAppointmentInserting" RowHeight="12px" OnAppointmentDataBound="RadScheduler1_OnAppointmentDataBound" OnTimeSlotCreated="RadScheduler1_TimeSlotCreated" OnFormCreating="RadScheduler1_OnFormCreating" NumberOfHoveredRows="3" FirstDayOfWeek="Monday" LastDayOfWeek="Sunday" OnResourceHeaderCreated="RadScheduler1_ResourceHeaderCreated">

It seems that the misaligned lines causes appointments to be misaligned as well: See attached image appointments.png. The three purple appointments should fill out the entire white areas (the appointment data indicates this when we debug) but they do clearly not.

Any ideas?

Extra div gets created in RadHTMLField on publishing page

Hi
I have an aspx page in a sharepoint site which has a RadHTMLField. When I edit the page and publishes it without updating the RadHTMLField, an extra div gets created as the outer div to the existing contents of the field. And this happens every time I publish the page after editing it.

The code looks like
<radE:RadHtmlField ID="RadHtmlField1" FieldName="FocusOn" AllowSpecialTags="true" AllowScripts="true" runat="server"></radE:RadHtmlField>

Can you plz suggest a script or some other resolution so that the extra div is not checked in with the page every time.
Regards

Modify RadconextMenu Items In Function of the created node

Hello,

I have a treeview and its context menu for which i initialize its items at the design time .
I populate the treeview dynamically. For each node, i want to configure the context menu differently ( ex: Add new contextMenu Items, change their text...). Can I do it at the server side? It seems that the contextMenu is not proper to the node, but to all the treeview? And the modifications are applied to the contextMenus of all the TreeViewItems..

Thank You for Clarification.

Whats the difference between OnClientCommandExecuting and RadEditorCommandList?

I've customized the editor toolbars by removing some buttons while adding my own custom buttons. I've implemented a clientside OnClientCommandExecuting handler to intercept and cancel keyboard shortcuts to the removed editor buttons. I also want to handle click events from the editor toolbar custom buttons.

Telerik documentation says to add onclick handlers to the editor's RadEditorCommandList. But, I've noticed that custom button click events are first processed by the OnClientCommandExecuting handler before they get to the RadEditorCommandList handlers.

What is the difference between using these two handlers? The custom buttons will instigate serverside save and saveas functionality via an ajax post. I'ld prefer to combine everything into the OnClientCommandExecuting handler, and to launch save/saveas ajax posts from there. After each launch I will cancel the click event.

<script type="text/javascript">

function OnClientCommandExecuting(editor, args) {

if ("Save" == args.get_commandName()) {

alert("OnClientCommandExecuting Save");

args.set_cancel(true);

} else if ("SaveAs" == args.get_commandName()) {

alert("OnClientCommandExecuting SaveAs");

args.set_cancel(true);

}

} //EOF OnClientCommandExecuting

</script>

<telerik:RadEditor ID="telerikeditor" Runat="server"

OnClientLoad="onClientLoad"

OnClientCommandExecuting="OnClientCommandExecuting">

<Tools>

<telerik:EditorToolGroup Tag="grpInputOutput">

<telerik:EditorTool ImageUrl="Images/radeditorSave.gif"

Name="Save" ShowText="False"

Text="Save" />

<telerik:EditorTool ImageUrl="Images/radeditorSaveAs.gif"

Name="SaveAs" ShowText="False"

Text="Save As" />

<telerik:EditorSeparator />

</telerik:EditorToolGroup>

</Tools>

<Content>

</Content>

</telerik:RadEditor>

<script type="text/javascript"

> 

     //locate this script after the radeditor HTML declaration

RadEditorCommandList["Save"] = function(commandName, editor, oTool) {

alert("RadEditorCommandList Save");

}

</script>

Shared sliders

Hi,

I need to put circa 20 sliders onto one page - a survey. I'd prefer to somehow use one shared slider - similar to with the calendar popup code. Is there an easy way to do this? Same goes for the slider items - worst case I suppose that I can add them from the server code but would prefer that I could use a shared calendar.

Any help much appreciated.

Cheers,

Jon

Problem to make disappear GridTempleColumn but ONLY for some lines

I have a complex problem:

I have in my Grid a GridTemplatecolumn which displays the text " rapport " but this text must be visible only for some lines

The condition to enable or disable the visibility is within the second if

protected void GridDisplayOldRDV_ItemDataBound(object sender, GridItemEventArgs e)

{

HiddenField HiddenFieldIdParticipant = e.Item.FindControl("HiddenFieldIdParticipant") as HiddenField;

Utilisateur utilisateur = (Utilisateur)Session["utilisateur"];

if (HiddenFieldIdParticipant != null)

{

if (utilisateur.idUtilisateur.ToString() != HiddenFieldIdParticipant.Value.ToString())

{

GridDisplayOldRDV.MasterTableView.GetColumn("Debriefing").Visible = false;

}

Right now , my problem is with this line :

GridDisplayOldRDV.MasterTableView.GetColumn("Debriefing").Visible = false;

The column disappears everytime...

I hope i'm clear enough

Thanks in advance for your help
