I have a page that I have has a fileExplorer on it.  All seems to work except the upload.  When I upload a file I always get this error and it opens a dynamic block of code.

JavaScript runtime error: Unable to get property 'get_selectedItem' of undefined or null reference

The file still uploads but not sure why this error is happening. 
I am runner version 2013.2.717.35 on a 2.0 framework asp.net app.

Hi

I have implemented the custom file browser as specified in the online resources. I am using shared paths like "\\172.0.0.0\images".

Everything else seem to work except for thumnails view.

I also tried cssclass - rfethumbnails but it doesn't help.

I have implemented all 4 methods that determine thumbnails for the images.

public override string GetFileName(string url)
        {
            string fileName = Path.GetFileName(RemoveProtocolNameAndServerName(url));
            return fileName;
        }
        public override string GetPath(string path)
        {

            // First add the '~/' signs in order to use the VirtualPathUtility.GetDirectory() method ;
            string PathWithTilde = "~/" + path;
            string virtualPath = VirtualPathUtility.GetDirectory(PathWithTilde);
            virtualPath = virtualPath.Remove(0, 2);// remove the '~' signs
            return virtualPath;            
        }
        /// <summary>
        /// Verify the file selected
        /// </summary>
        /// <param name="url"></param>
        /// <returns></returns>
        
        public override Stream GetFile(string url)
        {
            string virtualPath = RemoveProtocolNameAndServerName(url);
            string physicalPath = this.GetPhysicalFromVirtualPath(virtualPath);
            if (physicalPath == null)
                return null;

            if (!File.Exists(physicalPath))
            {
                return null;
            }

            return File.OpenRead(physicalPath);
        }
        public override string StoreBitmap(System.Drawing.Bitmap bitmap, string url, System.Drawing.Imaging.ImageFormat format)
        {
            string virtualPath = RemoveProtocolNameAndServerName(url);
            string physicalPath = this.GetPhysicalFromVirtualPath(virtualPath);
            if (physicalPath == null)
                return string.Empty;

            StreamWriter bitmapWriter = StreamWriter.Null;

            try
            {
                bitmapWriter = new StreamWriter(physicalPath);
                bitmap.Save(bitmapWriter.BaseStream, format);
            }
            catch (IOException)
            {
                string errMessage = "The image cannot be stored!";
                return errMessage;
            }
            finally
            {
                bitmapWriter.Close();
            }
            return string.Empty;
        }

I have
<telerik:GridNumericColumn ID
                            DataField="PricePerUnit"  
                            HeaderText="Unit Price"
                            HeaderStyle-HorizontalAlign="Center"
                            UniqueName="PricePerUnit"
                            ItemStyle-HorizontalAlign="Right"
                            DataFormatString="<%$Resources: DataFormats, PRICE_WITH_DOLLAR %>"
                            ></telerik:GridNumericColumn>

I want to catch GridNumericColumn in code behind and set read-only = true;

My scenario is:
If( !theUser.CanEditPrice)
{
  //something like this   
  // myGrid.GetGridNumericColumn("PriceID").ReadOnly = true; // maybe i needed to set ColumnEditorID ?
}

Hai,

Is it any other property for setting nocolor as Transperant color?

If i set Nocolor in the RadcolorPicker it always Display in Black Color
Please Guide me to do that.

Thanks,

Hello ! 

I'm trying to ajaxify the filter textboxes of my grid, and only them, so I don't want to use the following option : 


Ideally, I would like to use the solution below, but the filter textboxes don't have a defined Id, so this is not an option either : 


The only option I found is this one : 


But for some reason it's not working, when I set a filter on my "MyfirstColumn" the entire page is reloaded, the ajaxsetting seems to be completely ignored by the process. 

Any idea of what could be the reason ?

Thanks for your help ! 

Telerik Captcha is not displaying most of the time in IE. Also it is not generating any new image , it displays grey box when clicked on "Generate New Image". I have tested in IE 9.

Good day,

We need help with the following problem:
We have a masterpage with 3 different contentplaceholders. One of these (the 'body' contentplaceholder) loads a simple page, which is basically straight from your radwindowmanager samples from here: http://demos.telerik.com/aspnet-ajax/window/examples/windowmanager/defaultcs.aspx

In this 'body' we have the a button:
 runat="server" OnCommand="openalert_Click"

In the cs

    protected void openalert_Click(Object sender, CommandEventArgs e)
    {
        ViewAlert(rwp, "test", rwp.Page);
    }

where the ViewAlert function is basically this:

public static RadWindowManager ViewAlert(RadWindowManager radWinmanager, String Warning = null, Page pTarget = null) {
  string radstrcommand = "radalert('" + Warning + "', 200, 200, 'Test', null);";
  System.Web.UI.ScriptManager.RegisterStartupScript(pTarget, pTarget.GetType(), "call_radalert", radstrcommand, true);
}

Our problem is that any and all attempts to successfully open a radalert after pressing of the button are met with failure.
Using firebug we know that
radWindow is undefined
and
GetRadWindowManager returns undefined
whenever the page reloads after the RegisterStartupScript

We conclude this to be a timing / load order issue of some sort, related to the load time of the radWindow in respect to the trigger of the RegisterStartupScript, but how are we supposed to solve it?
Is there perhaps a better approach to manage the RegisterStartupScript (we don't use ajax for this particular case since we need a postback)

Thanks in advance

help me plz.............

 

It seems that the Font Face command does not actually fire, or at least does not insert its span with a font-family style, into the Content area of the RAD Editor until you actually start typing.  Therefore, if you select a font, then immediately use another command, such as Bold, the selected font is "forgotten".  When you  start typing, you will see that a <strong></strong> tag has been inserted, but the "font span" that should have been inserted when you selected a font is missing.

To reproduce the problem:

Select a font
Use any other control, such as Font Size or Bold
Notice the Font You chose has been reset
Begin Typing
Notice you are not typing in the font you selected.
Switch to HTML view, and notice that there is no <span style="font-family"> tag

I have tried injecting that "font span" immediately into the content area during the "OnClientCommandExecuting" event, when the command is "FontName".  Unfortunately, while this does insert the font span, it also puts the cursor AFTER the injected span, so when the user executes another command, such as Bold, the font selection still appears not to be effective.  To remedy THAT problem, I attempted to get a Range object from the current selection, manipulate its start/end, and then select it.  However, I could not make that strategy work reliably.

Help?
