When I set RadWindow property VisibleTitlebar="false" then top border is missing on window.
Here is sample code:
<telerik:RadWindow runat="server" ID="GenerateReportWaitWindow" Width="440px" Height="200px" 
                    VisibleTitlebar="false" Modal="true" ReloadOnShow="false" VisibleStatusbar="false" 
                    VisibleOnPageLoad="false" EnableShadow="false" Animation="Fade" Behaviors="None"
                    Title="Čakajte prosím...">
                    <ContentTemplate>
                        <div style="min-height: 66%;">
                            <div style="padding-top: 30px; padding-bottom: 45px; text-align: center; font-weight: bold;">

                                <asp:Label ID="Label5" runat="server">(V závislosti od počtu záznamov to môže trvať aj niekoľko minút...)</asp:Label>
                                <asp:Label ID="Label6" runat="server" ForeColor="Red" Style="display: none;"></asp:Label>
                          
                            </div>
                            <div style="margin-left: auto; margin-right: auto; text-align: center;">
                                <asp:Image ID="Image2" runat="server" ImageUrl="~/Images/Animated/loading1.gif" />
                            </div>
                        </div>
                    </ContentTemplate>
                </telerik:RadWindow>

Admin comment:
Actually there is 1px top border, but it is hard to be noticed. As a temporary solution, one can increase it via the following padding:

Copy Code
<style>
    .RadWindow {
        padding: 4px 5px 5px !important;
    }
</style>

While changing the value from RadCombox, meaning firing the SelectedIndexChanged, I am getting the below error.

When trying on localhost SelectedIndexChanged of RadCombobox is getting fired and rgrid_NeedDataSource of RadGrid is not fired but when deployed on IIS, the scenario is opposite, SelectedIndexChanged is not fired but rgrid_NeedDataSource is getting fired.

Please help.

Also another thing, I wanted to understand how to use licenses.licx file in our project for telerik dll version 2013.1.314.45?

Hello Progress team,

we're using the HtmlChart and RadialGauge components of your Telerik for AJAX suite and are encountering some inconsistencies between the two.

To be able to use the exportable SVGs of those components server-side, we've extended your classes and added two asp:HiddenFields each, so we can post the SVG and the dimensions back to the server for further processing. (Setting the values is handled in a button OnClientClick JavaScript function, that's irrelevant to this thread.)

As of 2019, when we first introduced the respective feature in our software, the code looked like this:

• Similar for both components
• In both cases the additional HiddenFields get added to the Controls-List "OnInit" before the base.OnInit-event.
• In both cases we had to override the "Render"-function to also render the HiddenField-Controls to the HTML.

public class ExportableRadHtmlChart : RadHtmlChart, INamingContainer
{
    private HiddenField _svgData = new HiddenField();
    private HiddenField _svgDimensions = new HiddenField();
    public ExportableRadHtmlChart()
    {
        _svgData.ID = "SVGData";
        _svgDimensions.ID = "SVGDimensions";
    }

    protected override void OnInit(EventArgs e)
    {
        Controls.Add(_svgData);
        Controls.Add(_svgDimensions);
        
        base.OnInit(e);
    }
    
    protected override void Render(HtmlTextWriter writer)
    {
        writer.RenderBeginTag(HtmlTextWriterTag.Div);

        base.Render(writer);

        _svgData.RenderControl(writer);
        _svgDimensions.RenderControl(writer);

        writer.RenderEndTag();
    }
}

and

public class ExportableRadRadialGauge : RadRadialGauge, INamingContainer
{
    private HiddenField _svgData = new HiddenField();
    private HiddenField _svgDimensions = new HiddenField();
    public ExportableRadRadialGauge()
    {
        _svgData.ID = "SVGData";
        _svgDimensions.ID = "SVGDimensions";
    }

    protected override void OnInit(EventArgs e)
    {
        Controls.Add(_svgData);
        Controls.Add(_svgDimensions);
        
        base.OnInit(e);
    }

    protected override void Render(HtmlTextWriter writer)
    {
        writer.RenderBeginTag(HtmlTextWriterTag.Div);

        base.Render(writer);

        _svgData.RenderControl(writer);
        _svgDimensions.RenderControl(writer);

        writer.RenderEndTag();
    }
}

With this code, we've been running the Telerik product version 2023.1.323.45.

Now, we've updated to Telerik product version 2025.1.416.462 and are experiencing the following inconsistencies:

1. Using the same code as before, the HiddenFields of class "ExportableRadHtmlChart" render twice:
   
   
   Whereas previously, they've only rendered once:
   

   

   Removing the custom "Render"-function of the class "ExportableRadHtmlChart" resolves this issue. (Having duplicates of those HiddenFields actually causes issues on repeated PostBacks, as two HiddenFields at a time have the same ClientID and thus their values get packed as a comma separated list before transmission to the server, which in turn yields issues when parsing the SVG, which in reality are multiple comma separated SVGs.
   
   The SVG values are truncated in this view, but the dimensions paint a pretty clear picture, as to what's happening here after 4 PostBacks.) Despite requiring to make this adjustment to our software, we're glad, we can discard that custom "Render"-function.
   
2. The "ExportableRadRadialGauge", on the other hand, still only renders the HiddenFields with the custom "Render"-function included. Can we expect a similar fix to the RadialGauge, s.t. we don't require to render the HiddenFields ourselves?

As I'm unsure of the "Theme name", I've put "ControlDefault". But I don't think that should matter too much. If it does, I'll try to find the correct value.

Kind regards,
Matthias

I have a RadEditor that is rendered in mobile mode on a mobile device emulator in Chrome browser.
For this editor, I have subscribed to OnClientCommandExecuted event. The event fires, but the problem is that it fires twice for ToggleScreenMode command.
To reproduce this issue, you can use the page code below and render it in Chrome mobile emulator; then press on edit pencil button followed by clicking the check button.

Position the cursor between the words SharePoint and Whether in the first paragraph and add a line break, after that press Backspace and you'll see that the new line does not disappear.

Adding new sections between existing paragraphs or after the last paragraph seems to work fine, but if you have to break up an existing paragraph into two paragraphs and then want to turn it back into one you won't be able to.

Hi,
I want to convert pptx files to PDF files.

Hello,

Sometimes the context menu isn't positioned correctly when it pops up for the first time, or after you scroll the page or do a browser zoom. I've attached an example reported by our tester. I've checked your technical support and have found this:

https://feedback.telerik.com/aspnet-ajax/1374622-context-menus-mispositioned-after-page-scroll-when-contentareamode-div?_ga=2.47056743.1148387732.1712639084-795296971.1689564005&_gl=1*1fbejbs*_ga*Nzk1Mjk2OTcxLjE2ODk1NjQwMDU.*_ga_9JSNBCSF54*MTcxMjcwNTQxNS42NS4xLjE3MTI3MDY1NTUuNjAuMC4w*_gcl_au*MTk5NTg1MzE3OS4xNzEyMjAwMDcy

I've tried setting the render mode to Lightweight (originally set to Auto), but unfortunately no luck.

Is this something that is fixed in a later version of the editor, or do you have another fix/workaround?

Thank you in advance,

Gerald

Hello,

I'm unsure whether this is an actual bug, but I can't seem to clear the selected text in the RadDropDownTree when i use UncheckAllNodes or UnselectAllNodes from the server side.

I try to to set SelectedText and SelectedValue on the RadDropDownTree control to string.Empty but neither works.

The nodes are unchecked though, but the text showing the previous selection is still visible after i  reload the page.

What should I do to also set the text to represent the selection done by UncheckAllNodes?

Kind regards,

Anders

There are issues with the cursor location when clicking at the end (or to the right) of a line in bullet lists with multiple levels.

When clicking at the end of the line the cursor is unexpectedly placed at the beginning of the line instead of at the end.

This does not happen if you click on some of the actual text or hit the exact location of the last character of the line, but when you naturally click just to the right of the end of the line.

It seems that it does not happen on all levels, but only some, as I have tried to depict in the attached screenshot.

This behavior was replicated on the latest WebForms Editor demo at https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

When scroll inside RadGrid in Chrome on a mobile device or in the DevTools responsive/mobile mode, the browser throws [Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See  https://www.chromestatus.com/features/5093566007214080. I get 1 error message for every pixel the grid scrolls. 

The problem is due to jQuery and is reproducible with 1.12.4 and 3.3.1 versions of it.

Hello,

Can you please add the control ID to this error so the affected control can be easily identified?  Right now, if you have a page with multiple combo boxes, it is extremely time consuming to locate the one with the issue.

Thank you,
DJ

Test Environment:

It would be great if telerik can provide remove blank data rows on column which helps when dealing with huge data.

I am able to achieve the logic with below code.

  var grid = $find('<%= RadGrid_MeaInfo.ClientID %>');
            // MasterTable
            var masterTable = grid.get_masterTableView();
            // Items/Rows
            var dataItems = masterTable.get_dataItems();

            for (var i = 0; i < dataItems.length; i++) {
                var item = masterTable.getCellByColumnUniqueName(dataItems[i], "TriggerMan")
                debugger;
                if (item.innerHTML == "" || item.innerHTML == undefined) {
                    masterTable.hideItem(i);
                }
            }
