Hi,
I have a modal RadWindow, whose content page contains a RadEditor. When an editor dialog is opened, it's position and movement is limited to the content area of the RadWindow. Is there a way to have the editor dialogs open modal, but relative to the browser? Thus allowing the editor dialog to be positioned overlapping or even outside of the RadWindow.
Thanks,
Dave

I'm using Q2 2015 (2015.2.826.45). My web form has RadCombobox with "CheckBoxes" set to true. I want SelectedIndexChanged fired only when the selected (checked) items are changed. However, I found when multiple items (3 or above) are selected, the SelectedIndexChanged event are always fired after postback. I think this is a bug. Please advise.

I'm pretty sure that this functionality hasn't been implemented by Telerik with the Kendo UI Diagram control.
Anybody out there got any ideas how to implement this - I've experimented with Select and had a look at the Range methods but nothing seems to cater for selecting any number of shapes and then arranging them equidistant apart.
Any pointers appreciated.

Hello,
I am new to a team of developers and one of our tasks is maintaining an older website that uses Telerik Rad controls.
I would like to identify if we need to upgrade the existing controls for security patches etc.
What is best way to determine what version of controls we have and how to update them if necessary ?
Thanks

Hi,
I'm using the Image Editor and setting the image url during page load. The image size is 5mb and the dimensions are 6000x4000
We are also making use of CanvasMode="On" which is causing the image quality to drop quite a lot.
Is there any additional settings that will enable us not to lose quality if Canvas is enabled.
Kind Regards,
Rumen

<ValidationSettings EnableModelValidation="False" EnableValidation="False" />
</telerik:RadListView>This is the code to set the datasource:
Protected Sub fileList_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.RadListViewNeedDataSourceEventArgs) Handles fileList.NeedDataSource
Dim filepath As String = appldata.getSYSTEMParam("ChapterUploadPath")
Dim files As New ArrayList(Directory.GetFiles(filepath, "*.xlsx").Length)
'Dim files As New List(Of String)
For Each f As String In Directory.GetFiles(filepath, "*.xlsx")
files.Add(Path.GetFileName(f))
Next
fileList.DataSource = files
fileDirectory.Text = "Alle Dateien im Verzeichnis " & filepath & ":"
End Sub
The effect is the same if I use list(of string) instead of arrayList.
The number of files read from the directory is 10. The ListView shows these then lines but indicates 1714 pages with 10 entries each. Paging is possible but only the page number changes, the list of 10 always shows in the same form.
How to reduce the listview to the real number of items present?

I'm using Version 2021.2.616.45 and attempting to detect Microsoft Edge. When using Edge in Windows 10, Telerik.Web.Browser.edge is false, but shows chrome is true. There are Telerik controls on the page, but I've also explicity added Telerik.Web.UI.Common.Core.js to the script manager. I get that Edge is a chromium browser, but I need to detect Edge.
Am I missing something?
Thanks,
Dave

I have a RadBinaryImage in a RadGrid template column and I'm trying to account for situations where the value is null. In reviewing some of the posts, I saw the following solution.
<telerik:RadBinaryImage runat="server" ID="RadBinaryImage2" DataValue='<%# Eval("vSignature") Is DBNull ? null Eval("vSignature") %>' AutoAdjustImageControlSize="false" Height="100px" Width="400px" ToolTip="Signature" AlternateText="Signature" />However, I get a design-time error stating that...
DBNull is a class type and cannot be used as an expression.
I have seen examples of this, but this does not work for me in Visual Studio 2017, Asp.Net 4.6.
Any help on this is greatly appreciated!

I have a project that uses the ASP.NET Ajax controls and I would like to upgrade to the newest version (2021). Is it just a matter of switching the DLLs and skins or are there breaking changes? After upgrading do I need to test every page with a Telerik control on it?
Thanks,
Tim
