I found an issue where I had a webpage that has an AsyncUpload control and a text field. If the user enters text that contains angle brackets with some text between the brackets, the AsyncUpload throws some type of error.

I was able to reproduce this problem in the Telerik demo:

https://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandradasyncupload/defaultcs.aspx?product=asyncupload

Steps:

1. Click "Add new record"

2. In the Image Name field type "test <test.com>"

3. Upload an image file

4. Click checkbox to add record

5. Error occurs.

Dear team members,

Is it possible to catch a drag event on client-side that occurs when a RadSplitBar is being dragged? I want to display the change of the position continuously.

Kind Regards

Good afternoon,

I'm looking to replace a CollapsiblePanelExtender with a Telerik control. The closest to this seems to be a RadSplitter.

How can I make a horizontal RadSplitter, which contains two panes, change its height to keep one pane at the top as a constant, but expand and collapse with a second pane. I'm using a button in the top pane to control the second pane, rather than a RadSplitterBar.

<telerik:RadSplitter RenderMode="Lightweight" ID="RadSplitter1" runat="server" Width="900px" Orientation="Horizontal">
    <telerik:RadPane ID="RadPane1" runat="server" Height="30px" CssClass="collapsePanelHeader">
        <div style="padding:5px; padding-left:20px; cursor:pointer; vertical-align:middle;" onclick="ToggleCollapsePane()">
            <div style="float:left;">
                <asp:Label ID="lblOptionsHdr" runat="server" Text="Filter Options" Font-Bold="True" />
                </div>
        </div>
    </telerik:RadPane>
    <telerik:RadPane ID="RadPane2" runat="server" Height="270px" CssClass="collapsePanelContent">
        <div id="divContent" style="padding:20px; vertical-align:middle;">
            <table style="vertical-align:top; width:100%; border-spacing:5px; padding:5px;">
                <tr>
                    <td>
......... several filter options (dropdown lists, radiobuttons)
                    </td>
                </tr>
            </table>
        </div>
    </telerik:RadPane>
</telerik:RadSplitter>

When the <div> in pane 1 is clicked it should toggle pane 2, and the splitter adjust its height accordingly:

        function ToggleCollapsePane() {
            var splitter = $find("<%= RadSplitter1.ClientID %>");
            var pane = splitter.getPaneById("<%= RadPane2.ClientID %>");

            if (pane.get_collapsed()) {
                pane.expand();
                splitter.resize(900, 303);
            } else {
                pane.collapse();
                splitter.resize(900, 33);
            }
        }

Is what I'm trying to achievable?  Or is there another Telerik control that does this?

Kind regards,

Richard

We are currently facing an issue with upgrading Telerik.Web.UI.dll  version from 2021.3.1111.40 to the 2024.4.1114.462 in our application.

Our application uses the RadScheduler component, which was functioning without any issues prior to the upgrade.

However, after upgrading to the 2024 version of Telerik.Web.UI, the Scheduler component begins throwing the attached error (stack trace attached Error2.png).

Upon investigation, it appears that the 2024 version of Telerik.Web.UI has a dependency on Newtonsoft.Json version 13.0.

Currently, our application utilizes Newtonsoft.Json version 12.0.

Upgrading to version 13.0 is not feasible in the short term due to multiple dependencies that require comprehensive testing.

We kindly seek your clarification and assistance with the following questions:

1. Can you confirm whether the Telerik.Web.UI 2024.4.1114.462 version has a dependency on Newtonsoft.Json version 13.0?
2. Is there any workaround available to resolve this issue without upgrading to Newtonsoft.Json version 13.0?

Your assistance and guidance on this matter would be greatly appreciated.

Thank you, and we look forward to your response.

Best regards,
Arvind Pandey.

Hello Telerik Team,

Our customers have found that using the tab and arrow keys for navigation through the radmenu is inconsistent.

For example, when a user tabs into a radmenu item, uses the arrow keys to navigate to other menu items, and then hits the tab key again, the selection jumps to the last tab location instead of the current arrow key location.

Is there any way to make the arrow keys behave the same as the tab key, please?

Thanks in advance,

Lan

How do I had a "Select All" option to a RadMultiSelect? I've see a couple of pages showing is but I can't find it in the docs or examples.

Thanks for any help.

I'm using server side validation for certain controls on an asp.net web form page, which also contains a RadAsyncUpload control. 

When a user clicks save, I check to make sure these certain controls contain a value.  If this fails, we stop the save process and display a message to the user.  

During this process, any files to be uploaded are lost.  I need to retain them.

In the load event following this post back, the RadAsyncUpload control still has the uploaded files, but after fully loading the page, they're gone.

I'm already using the Post back Triggers property and this save button just happens to be the post back trigger.

How can I capture these files and "re-load" them into the control?
