Hi, Please help me.

My project was working fine, until I upgrade Telerik to use the new radHtmlchart features.
Now, when I run my project I got this message:

Error en tiempo de ejecución de Microsoft JScript: 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 '�'.

What can i do?

Specify css location

This might be a bit hard to explain but basically im looking for a setting where I can specify where in the page the html editor is (in css terms) so it picks up on particular css.

It'll be easier to explain with an example.

So I hook the rad editor up to a particular css file :
radEditor.CssFiles.Add("<path to css file");

Then say in the css file there is a div with an id of test, and that div has particular style set in the css file.
What id then like to do is have the rad editor content styled as if it is located in the div with id of test, so it picks up on all relevent css relating to that div.

I think this probably isn't possible but just double checking?

[Solved] add two types of validation check to radbutton

Hello,
I have a two radtextbox, rad upload , radbutton and a seperate rad grid.
I already added validation to radtextboxes and rad upload using asp req field validator and custom field validator.

RadAjaxLoadingPanel not showing

Hello,
I have a problem with RadAjaxLoadingPanel:
my web application has a RadGrid control and a RadTreeView.
When I click on a node of the radtreeview the radgrid performs a rebind action and loads data associated with the node values.

I use a RadAjaxManager to perform the update/rebind action of the radgrid and i use a RadAjaxLoadingPanel to hide the radgrid while loading data.
The update process is correctly performed but the RadAjaxLoadingPanel is not displayed.

In my application there are other controls that trigger the update action of ther radgrid and the update is correctly performed and also the RadAjaxLoadingPanel is correctly displayed.

How can I fix my problem and make the RadAjaxLoadingPanel visible during the update of the radgrid when clicking on a Radtreeview node, like with the other controls?

A short part of the code is following:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" UpdatePanelsRenderMode="Block" EnableHistory="False">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="CheckBoxMerge">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="CheckBox1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadGridAccounts">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="ButtonEseguiFiltro">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="CatTree1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

CheckBoxMerge, CheckBox1, RadGridAccounts, ButtonEseguiFiltro perform correctly the update and also the RadAjaxLoadingPanel1 is displayed, while CatTree1(the radtreeview) performs the update but the RadAjaxLoadingPanel1 is ot displayed

[Solved] Duplicate RadControls in toolbox

Hi,

I am using Visual Studio 2008 SP1 and have just installed RadControls for ASP.NET AJAX Q1 2010. There have been no previous installations of RadControls or Visual Studio on this machine.

After installing RadControls for ASP.NET AJAX Q1 2010 I noticed that there are two of every RadControl in the toolbox.

Why is this and is there a way to fix it?

One usercontrol to edit data in a 2 lvl datagrid

Hi team,

Based on http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx, where I instead is working with a gridview with a hierarchy - i'm trying to create a user control wherefrom the user can update data from both levels of the datagrid when pressing 'Edit' on an item in the top level of the grid.

My problem is that for items within the second level I cant bind them as shown below: (for the top level)

<telerik:RadTextBox ID="FunctionTextBox" runat="server" Width="100%" Text='<%# DataBinder.Eval( Container, "DataItem.function_description") %>'></telerik:RadTextBox>

Is there a way to accomplish this?

I've also unsuccessfully been trying to access the gridview directly from the code behind file of the user control with the following:

RadGrid r = (RadGrid)this.Parent.FindControl("TerminalGrid");

Please let me know if you need more data and I'll try to supply it.

Thanks.
