When using a RadDropDownTree with CheckBoxes="CheckChildNodes" , setting CheckChildNodes="false" has no effect.

<telerik:RadDropDownTree ID="DdtDpt" runat="server" CheckBoxes="CheckChildNodes" CheckChildNodes="false" CheckNodeOnClick="true" 
    DataFieldParentID="pid" DataFieldID="id" DataTextField="name" DataValueField="id" Width="350px">
</telerik:RadDropDownTree>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        DdtDpt.DataSource = GetDummyDepartments();
        DdtDpt.DataBind();
    }
}

private List<Department> GetDummyDepartments()
{
    return new List<Department>
    {
        new Department { id = 1, pid = null, name = "Head Office" },

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="Label4" runat="server">Prebieha vytváranie tlačovej zostavy. Čakajte prosím.</asp:Label>
                              
                                <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>

Workaround - Toggle drop zone visibility or enable/disable it, using AsyncUpload OnClientFileUploaded and OnClientFileUploadRemoved events:

<div class="dropfile" style="height: 20px; width: 120px; background-color: red; display: block">
</div>
<telerik:RadAsyncUpload ID="fimFileImport" runat="server" DropZones=".dropfile" MaxFileInputsCount="1"
	RenderMode="Lightweight" OnClientFileUploaded="OnClientFileUploaded" OnClientFileUploadRemoved="OnClientFileUploadRemoved" >
</telerik:RadAsyncUpload>

<script type="text/javascript">
	function OnClientFileUploaded(sender, args) {

		var maxFileCount = sender.get_maxFileCount();
		var uploadedFilesLength = sender.getUploadedFiles().length;
		
		if (maxFileCount === uploadedFilesLength) {
			$telerik.$('.dropfile').hide();
		}
	}

	function OnClientFileUploadRemoved(sender, args) {

		var maxFileCount = sender.get_maxFileCount();
		var uploadedFilesLength = sender.getUploadedFiles().length;

		if (maxFileCount > uploadedFilesLength) {
			$telerik.$('.dropfile').show();
		}
	}
</script>

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?

When a RadGrid has the "AllowScroll" property set to True and is populated via a DataSourceID, calling the ExportToExcel() method on the grid results in the grid immediately rebinding. This undoes any changes made to the grid, like during the recommended way to export Template columns. When AllowScroll=False, the grid does not rebind and Template columns are exported, as expected.

The panelbar item you click on selects the first root item of the panelbar, then changes to the actual selected item. This can be observed in the Custom Attributes demo.

Accessibility Management Platform (AMP) reports that the Telerik Web Forms ComboBox has an attribute mismatch

This element has a mismatch between the value of its readonly and aria-readonly attributes

 

The following structure replicates the error

<telerik:RadComboBox ID="RadComboBox1" runat="server" EmptyMessage="Empty Message" EnableAriaSupport="true">
    <Items>
        <telerik:RadComboBoxItem Text="Item 1" />

Hi,

I was looking around to develop a web app that allows streaming camera view in order to take pictures, showing the previews, letting cancel/retake or transfer (upload/save) them.

I started from the input control, that makes more or less what I need, but start a video streaming, letting the user simply to capture frame from it to save pictures, is more user friendly and simplify a lot the workflow.

So I started to work with video element, canvas and FloatingActionsButton, hitting against many issues, starting from the different browsers compatibilities.

I was just wondering if Telerik would never implement such a camera + gallery component, in order to take and manage pictures easily and cross platform.

Thank you, kind regards

Please create a Bootstrap 5 skin so we can use Bootstrap 5 along with Ajax components on the same page and colors/spacings and everything else would look the same. Current Bootstrap 3 skin is limiting to use Bootstrap 3 on other page elements

Yes, ASP.NET Webforms is outdated, but it's still around, and I think many developers are looking at moving to a newer and more modern technology. But in some cases - including mine - it's not really possible to refactor an application that has grown for 20 years overnight. The only thing I can do is put a lot of energy into changing the CSS of the controls. Which is not always easy.

I really appreciate the functionality of the Telerik controls and think it's a shame that they don't get a visual and functional update.

In this specific case, it is about the Datepicker Control, which has a different behavior than the more modern version under .NET Core. For example, the month or year selection opens in a new DIV popup. In the more modern control, this is solved in a more elegant and modern way.

I think that this list of controls that need a “front-end pimp” can certainly be extended.

Thank you!

Based on Ticket ID 1683806  it was suggested to add this here.  It should be fairly straight forward and would resolve issues that I have.

My Suggestion:

Why can you not just add the clientEvents to the RadEditor1.FileExplorerSettings

Something like RadEditor1.FileExplorerSettings.ClientEvents.OnClientFileOpen="somefunction"

 

Your response.

Thank you for your suggestion to add client events directly to RadEditor1.FileExplorerSettings. It's a thoughtful idea that could indeed enhance client-side flexibility and streamline interactions.

At present, this feature is not available. However, we encourage you to submit it as a feature request through our public feedback portal, where our product team actively reviews community input for potential inclusion in future updates.

 

Also, please see my ticket for a bug in the ImageManager using th URL to return the item instead of the OriginalPath.  This makes my custom content provider not feasible.

 

 

Thanks!

Noticed that when using a template to custom define the pager look, the pager gets rendered in a TD and not a TH as expected since the pager is in a THEAD.  Could the header pager only be modified to render in TH?  This would allow all elements in the header to render the same and help with styling.
