Hi,

We are trying to upgrade our application to the latest Telerik UI for ASP.NET AJAX (2025.3.812) and we are experiencing an issue with spell check.

In the latest version words with a ' in them eg "Darren's" are flagged as a spelling mistake as "Darrenss" where the ' is replaced with the letter after it. Even if you click ignore it still replaces the original text with the version with the extra s.

The use of spell check is enforced in our application so this preventing us from upgrading.

You can reproduce the issue on the Telerik spell check demo page here:
https://demos.telerik.com/aspnet-ajax/spell/examples/overview/defaultcs.aspx

Can you please confirm if there is a work around or a fix available?

Thanks

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" },
        new Department { id = 2, pid = 1, name = "HR" },
        new Department { id = 3, pid = 1, name = "IT" },
        new Department { id = 4, pid = 3, name = "Development" },
        new Department { id = 5, pid = 3, name = "Support" },
        new Department { id = 6, pid = null, name = "Branch Office" },
        new Department { id = 7, pid = 6, name = "Sales" },
        new Department { id = 8, pid = 6, name = "Logistics" }
    };
}


public class Department
{
    public int id { get; set; }
    public int? pid { get; set; }
    public string name { get; set; }
}

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>

The issue reported previously - Uncaught TypeError: Cannot read properties of null (reading 'className') - is still present if setting the <compilation debug=”true”> in the web.config and EnableScriptCombine="false" in the ScriptManager.

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?

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" />
        <telerik:RadComboBoxItem Text="Item 2" />
        <telerik:RadComboBoxItem Text="Item 3" />
        <telerik:RadComboBoxItem Text="Item 4" />
    </Items>
</telerik:RadComboBox>

Hi,

Would it possible to build in a text search filter into a Listbox?

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
