Grid / PopUp Edit Form Validation? Keep Window Visible....

The PopUp Edit Form window disappears when I try to insert or edit my information even with validation controls in the form. What's the best way to keep the PopUp Edit Form window visible until the information entered is valid?

I tried this but the window still closed.
            if (e.Exception != null)
            {
                e.ExceptionHandled = true;
                SetMessage("Product cannot be inserted. Reason: " + e.Exception.Message);
            }
            else
            {
                SetMessage("New product is inserted!");
            }

Thx

RadGrid - Insert/Update on Enter

Hi,

I have a radgird which allows the user to insert a new record using a form template. However, when the user enters the required information, then presses enter the insert command is not fired.

Is there any way to wire up the grid to force an insert when the user presses enter?

Thanks

Possible RadDateInput bug with EmptyMessage attribute?

Hi all,

I wonder if there's a fix with this issue.

After upgrading Telerik ASP.Net AJAX Q3 2009 from Q1 2009, there is an issue with RadDateInput with EmptyMessage attribute. Here's the code snippet.

    
            <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title></title> 
        
                <telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" /> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
                    <Scripts> 
        
                        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" /> 
        
                        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" /> 
        
                    </Scripts> 
        
                </telerik:RadScriptManager> 
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                </telerik:RadAjaxManager> 
        
                <div> 
        
            <telerik:RadDateInput ID="RadDateInputDOB" runat="server" Skin="WebBlue"  
        
                            Culture="en-US" MinDate="01/01/1900" MaxDate="12/31/2999" MaxLength="10" 
        
                            DisplayDateFormat="MM/dd/yyyy" 
        
                            EmptyMessage = "MM/DD/YYYY" 
        
                            DateFormat="MM/dd/yyyy" Width="120px"> 
        
                        </telerik:RadDateInput> 
        
                        </div> 
        
                <asp:Button ID="Button1" runat="server" Text="Button" /> 
        
                </form> 
        
            </body> 
        
            </html>

When the RadDateInput has empty value, it's the following bug. Here's the step to reproduce.

Leave RadDateInputDOB without value.
Press Button1 and return to the same page.
Wait the page is refreshed. I notice RadDateInputDOB display changes from greyed to black, indicating there's value.
Click RadDateInputDOB. Notice the value becomes 0NaN/0NaN/0NaN.
When RadDateInput is out of focus, the vlaue becomes 12/31/1998, not blank.

I can get rid of this issue by removing EmptyMessage attribute. But I need to put the EmptyMessage value back eventually.

Thanks in advance.

Performance Problem in opening the edit form with the Web Usercontrol

Hi,

We are using the Rad Ajax Manager in the Master Page, Ajax Proxy in the Content Page and one More Ajax Proxy control in the User Control. We the grid edit form, it reloads the screen each time. You can check the screnario in the below application.didnt used the Session object to retrieve the data. When we open

http://test.aptisys.com/UOMSetup.aspx

Where as in your example demos of using the webuser control in the grid. It is quite faster in opening the edit form and there is no reloading of the page. When we check with the firebug, we found that in your example demos the page is faster on opening the edit form not reloading the page. Is it because of the session object that was faster in your example? If we include the session for caching, does it takes large amount of data in the cache, does it causes any performance problems? Could you please send example program with RadAjax Manager in the master page, Ajax Proxy in the Content Page with the grid and one more ajax Proxy in the Web User control for the edit form with the same performance as your demo example as mentioned in the URL example?

Thanks & Regards

RadScheduler Docs error IV

OK I know that you know that the docs need work.

But I don't know if you know which bits are wrong.

The code examples for the events Appointment_Insert, Appointment_Update and Appointment_Delete, but, oddly, not Appointment_CancellngEdit, all declare the method as private meaning it won't compile it the event is defined in the markup.

How do I assign WebService Proxy?

I am using the Scheduler with the WebService for all the data binding. I have custom data provider that talks to the database and used into the contoller for the webservice. It works fine when it is used with the setting: ResourcePopulationMode="ClientSide". When I change it to ResourcePopulationMode="ServerSide", I get the error. The reason is that webservice is secured by forms authentication and I need to pass in the credentials before I make calls to the webservice. I tried to see if I can create and assign proxy myself with no success. Looks like it only takes the path to the webservice url. How would I solve this problem?

Thanks a lot...

Ajax spinner, RadFileExplorer, ASP.Net Development Server and Form Authentication combo problem....

I discovered this problem today and believe it may be of benefit to the community...

I have a RadFileExplorer and have implemented my own FileBrowserContentProvider that bounces off our database.

Very often when I click on a folder the ajax loading doughnut appears and does not go away. If I repeatedly click on another folder and then back to the original the doughnut will disappear and the directory listing will appear successfully.

The problem never occurs on a folder with no subfolders or files. But it does occur if the folder has a single subfolder or file.

When it stops working it is associated with an exception appearing in the Visual Studio output window....

A first chance exception of type 'System.Runtime.Serialization.SerializationException' occurred in WebDev.WebHost.dll

I enabled exception breaking on this exception and the stack trace showed....

I have discovered what it is though. It is unrelated to Telerik. I am running against ASP.NET development server and we have forms authentication. Often we receive the exception...

This is a well known short coming of ASP.NET development server running against forms authentication.

It appears that this same problem is responsible for the problems with RadFileExplorer.

When I turned off forms authentication RadFileExplorer started working perfectly.
