Hi

I am trying to display a column of checkboxes in Telerik RadGrid in my project.
The data source of my grid is a list of objects.
How to do this  programatically ?

p.s.
an answer in any programming language will be appreciated 

my code:

    

my aspx:

Hello,

I've been searching for a while now, but I cant find out how I can make a RadNotification part of the RadAjaxPanel. In my scenario, the notification is shown, but when I click a button in the contentTemplate of the RadNotification, a full postback is created in stead of the partial one with the loadingPanel.



Any ideas on this?

Kind regards,

Erik

Hi Telerik team,

I am a newbie programmer and have been using Telerik since a couple of months now.

I am trying to implement the follwing process:

1. User uploads an Image on RadImageEditor using AsyncUpload
2. User crops the image
3. User clicks on CreateProfile button on the page.
4. The cropped image should be stored in the database.

Problem: The uncropped version of the image gets stored. I think I am doing something wrong. Would be great if you could help

Code:

.aspx

<telerik:RadImageEditor  ID="ImageEditor_CreateNewUser"   CanvasMode="No" runat="server" Height="500px" Width="700px"     OnImageLoading="ImageEditor_CreateDonor_ImageLoading" OnClientCommandExecuting="OnClientCommandExecuting">
</telerik:RadImageEditor>

<asp:Button ID="BtnDonorSave" Text="Create Donor" ValidationGroup="CreateDonorSubmit" runat="server" OnClick="BtnDonorSave_Click" />

  .aspx.cs - 

        protected void ImageEditor_CreateNewUser_ImageLoading(object sender, ImageEditorLoadingEventArgs args)
        {
            if (!Object.Equals(Context.Cache.Get(Session.SessionID + "UploadedFile"), null))
           {
                using (EditableImage image = new EditableImage((MemoryStream)Context.Cache.Get(Session.SessionID + "UploadedFile")))
                {
                    args.Image = image.Clone();
                    args.Cancel = true;
                }
           }
        }
 protected void BtnDonorSave_Click(object sender, EventArgs e)
        {
             EditableImage ei = ImageEditor_CreateDonor.GetEditableImage();
            MemoryStream s = new MemoryStream();
            ei.Image.Save(s, ei.RawFormat);
            byte[] imgData = s.ToArray();

            db.CreateUser(userId, imgData);

}

where can I download the latest version of italian resx file?

Thanks!

Hi there,

I check the display-property of the columns of a RadGrid on PreRender, but it isn't actual.

If I Hide/Show another Column or sort a column, the PreRender Function gives the correct display-property.

Here my code:

Good morning! I am facing a problem when I resize the RadDock I trigger, and then try to change page it appears the following error:

Erro em tempo de execução do JavaScript: Sys.WebForms.PageRequestManagerServerErrorException: The numeric part ('184,28570556640625') of '184,28570556640625' cannot be parsed as a numeric part of a Pixel unit.

Which form to be able to resolve this problem? I'm using the language of the browser in Portuguese, it brings this error when I use English and it does not show any errors.

I await response Thanks!

I installed the .NET Telerik controls (AJAX) and the extensions for VS 2013 and I want to generate a web application targeting .NET 4.

If I target .NET 4.5.1, then the tools appear in the toolbox but if I target .NET 4 then they do not.

It seems the controls can still be used in older .NET versions as I can paste code for the controls into my .apsx files in my .NET 4 project and they seem to work OK.

I need the latest version of the controls and VS as I need to target both touch and mouse devices as well as some older browsers.  Can I safely do this?  What are the implications?

It appears that there may be a date format issue related to the RadScheduler and the ODataDataSource.  While it works with an OData Version 2 date, it fails if the ODataDataSource is pointed to an OData Version 3 web service.  I receive the following javascript error related to date parsing:

     Error: Unable to get property 'length' of undefined or null reference

Our OData Service returns "2014-03-14T23:00:00" with version 3 while the older version returns dates like /Date(1394838000000)/

Can you confirm that this is a bug on your end?  We are using the 2014 Q1 update which allowed us to upgrade our OData service to Version 3.

I have 3 dropdowncolumns in this radGrid.
The first one "Pnum" is working well, I can select the value and save it, and the saved value is visible in the grid when not in edit mode. If I open the record in edit mode the dropdown stays on the selected value unless I select a new value.
The other two dropdowncolumns are giving me problems. The selected value is saved to the db but is not visible when the grid is not in edit mode and if I open the record in edit mode after having saved it,  the dropdown value is on the default value.

How can I have the two dropdowncolumns "minutes" and "hours" acting like the "Pnum" column? Why they are acting in a different way?

I mean after selecting the value and update the record have the value shown in the grid.
