Hi, I need help for the following problem.

Scenario:
I am trying to update RadGrid with outside dropdown using RadAjaxManager. I need to do this only when the RadGrid is actually included on the page and when the FormTemplate is shown. This "included or not" is determined by page code behind (on the form that contains the grid) using TDs and making them visible or not, which depends on what's selected on the form by the user.

The control where it all is declared is attached (ascx and ascx.cs). This control is loaded dynamically with other controls in one single page. Trying the RadAjaxManager like attached, it gives me the following error:

Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl08_ctl00_ctl08_RadGrid1Panel'. If it is being updated dynamically then it must be inside another UpdatePanel.

I suppose this is because the RadGrid is not present yet on the form.
So how can I update the RadGrid from the outer form only when it is present?

Sorry for not attaching classes because they are rather long, but at least here's the xxx declaration:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
   <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="ddlMotivoGasto">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="ddlMotivoGasto" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"></telerik:RadAjaxLoadingPanel>

If you need any more code I'll be happy to provide.

Thanks in advance for your kind help.
Regards, Pieter

Hi,

We are using "RadInput.Net2.dll" and RadMaskedTextBox for phone number. For validating phone number format as (###) ###-####, we are using RegularExpressionValidator.

Below is the code we used

 <radI:RadMaskedTextBox ID="txtPhone"  runat="server"></radI:RadMaskedTextBox><br />
             <asp:RegularExpressionValidator ID="revOtherPhone" Display="dynamic" ControlToValidate="txtPhone" ValidationExpression ="^(\([0-9]\d{2}\)|[0-9]\d{2})[- .]?\d{3}[- .]?\d{4}$" ToolTip="Input other phone" ErrorMessage="Enter the correct phone number." runat="server"></asp:RegularExpressionValidator>               

The functionality is working fine OnKeyPress event.
But we do not want to display the error message on every key press. We want to display the error message only on tab / mouse out from text box like demo available in "http://demos.telerik.com/aspnet-ajax/input/examples/common/validation/defaultcs.aspx"

But we have used the same code as mentioned in the demo source code. But we are getting the validation message at every key press event instead of tab out.

Iwe could not find out where the RegularExpressionValidator validation event is setup for RadMaskedTextBox key press. Could you please help me to fix this issue?
Thanks in advance.

We are using "RadInput.Net2.dll" and RadMaskedTextBox for phone number. We want to check if first character of area code should not be 0 or 1.

If we use CustomValidator and javascript as below, it is working fine.
For example, if phone # is "(316) 446-2777" and if I replace 3 as 1, I could see the correct error message. But if I delete 3, I can see numbers in text box as "(_16) 446-2777". But still I can see the error message as "This number cannot begin with a 1 or 0.". The prompt character is not part of the args.value.

I want to display the error message only if first character after ( is 0 or 1. Could you please help us to find out the first character only of the input text
Thanks in advance.

Currently when I click on an appointment to drag it it moves to cover the topmost appointment and goes semi-transparent.
After I have moved the cursor to the position I want the appointment to be in and released the mouse button it just jumps back to where it was before.
Is there any way to re-order items and save the order they were in?
Thanks,
Edward

I have a treeview which I'm loading on demand via a webservice.

My webservice sets attributes on the nodes to indicate a) whether or not to show the checkbox for that node and b) whether or not the checkbox should be checked.

My treeview has 2 levels.

When the WebService call succeeds, the following code is called to populate the tree...

And, on the face of it, this appears to work.

However, it seems that this code is only being called for the top-level nodes in the tree. None of the child nodes are being processed by this code. In fact, this code doesn't appear to be being called at all for anything other than the top-level nodes.

Clearly, I'm missing something. Can anyone give me an idea about what it might be?

I intend to implement 'Drag and Drop' in rearranging Tabs at run-time.
I choose to work with the RadGrid's 'Drag and Drop' feature for Column header rearranging. 

Changing the Layout/CSS for every column header item seems doable. But, I need scroll features like in TabStrip without a scrollbar. Any idea how I could do this? 

I am using ASP.NET AJAX Q3 2010 and have upgrade up to Q3 2011.

Thanks,

I have the trial version. I drag and drop the RadUpload onto my page. I do not see the "Upload All" button for uploading the file. Is this due to because it was a trial version only?

I got this error when I tried to load the page with the RadUpload control and RadScriptManager.

Server Error in '/' Application.

Hi,

We are having some problems with the Opera 11 and AutoResize of the RadWindow.
We are setting an url to the window. If the content of the window is small (less than 350px) our RadWindow still becomes 350px high (with white space below).

When checking out the autosize source code in Telerik, I discovered the following lines of code:

When I did a prototype on the entire autoSize function and including Opera in the if statement, everything worked as expected!!!
Don't know if there are side-effect of this, but normally Opera behaves like these browsers so it should be OK.

Is this something you might fix in a future release?

I'm trying to get a basic Schedule running, but I'm getting an error:

Provider 'SchedulerData' has not been declared in web.config

Here is my web.config section that defines it:


and here's the very basic tag I'm using to initiate it:


Can anyone see what I'm doing wrong? I'm using the MyDbSchedulerProvider.cs file that was included and I've changed it to match up to my database table and fields. Thanks.
