Dear Support Team,

we are currently trying out RadPdfViewer and have found that hyperlinks in the PDFs do not work.

During my research, I found that this has now been implemented for the Kendo UI PDF viewer for Angular (https://www.telerik.com/kendo-angular-ui/components/changelogs/kendo-angular-ui#v18.5.0).
Will this also be implemented for the ASP.NET viewer, and if so, when?

Best regards

Frank

Getting javascript error:

Hi Team,

I would like to request a way to insert a new record at the bottom of the InPlace Editable RadGrid so that the row would be within the RadGrid container.

Thank you!

Hi, 

I am using the pdf viewer control and can't find anything on displaying the PDF document in a 2 page spread mode e.g. page 1 and 2 side by side, 3 and 4 side by side etc.

Does the control support this?

Thanks

Hi,

    many customers are asking us a more MS Word-like editor supporting true document layout features such as:

• page margins and rulers
• Headers and footers
• section breaks or document structure more similar to MS Word
• Microsoft Word-inspired UI

Many thanks,

Max

The bottom part of the last page of the PDF document stays hidden. If dragged with the mouse, the Page will move and can be viewed, releasing the mouse will scroll it back as a result, hiding the bottom part.

Issue can also be observed with the following demo: https://demos.telerik.com/aspnet-ajax/pdfviewer/overview/defaultcs.aspx 

Hi 

I have a RadEditor control where some toolbar functionalities are not working.

After searching for a possible reason, I used the OnClientCommandExecuting client-side event and noticed that sometimes, instead of the args with its value, I found the item of a RadTreeList control present on the page.

I tried to reproduce the issue by inserting an Editor and a TreeList on a page. I write some text in the Editor and try to change the color or background. Not always (and I can't figure out when), but sometimes the args are incorrect.

For example, if I open a node of the tree, the error is almost certain after that.

I send you an image of my javascript debugger.

I don't know what I can do, do you have any ideas?

Thanks

Michela

I am receiving the following ADA Compliance errors, when running a page scan for WCAG 2.1 AA:

Buttons must have discernible text: button.rcbActionButton

<button class="rcbActionButton" tabindex="-1" type="button">select</button>

Form elements must have labels: input.rcbInput.radPreventDecorate

<input name="ctl00$MainContent$MyCombo" type="text" class="rcbInput radPreventDecorate rcbEmptyMessage" id="ctl00_MainContent_MyCombo_Input" value="Search..." autocomplete="off"></input>

This is the component:

Hello -

I just updated my components to 2025.1.218, and am receiving the following ADA Compliance issues on a page scan.  This is to conform to WCAG 2.1 AA.  The component is the Ajax telerik:RadComboBox:

Buttons must have discernible text

<button class="rcbActionButton" tabindex="-1" type="button">select</button>

Form elements must have labels

<input name="ctl00$MainContent$ComboBox$NewCombo" type="text" class="rcbInput radPreventDecorate rcbEmptyMessage" id="ctl00_MainContent_ComboBox_NewCombo_Input" value="Search..." autocomplete="off"></input>

Component in .ascx file:

Please advise.  Thanks!

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!

While trying to update to latest version of Telerik ASP.Net Ajax, we are getting following exception:

An error occurred while running the wizard.

I would request to have the upgrade wizard handle it and show a graceful message instead of throwing the exception as it is doing right now.

Scenario description and workaround follow. Note the comments in the workaround and test before using, because it introduces some other unwanted behaviors, mostly related to the bottom/right edge of the zone.
       
WORKAROUND 1:

     <div id="zone" style="width: 600px; height: 500px; background: yellow;"></div>
            <telerik:RadWindow runat="server" ID="rw1" RenderMode="Lightweight" VisibleOnPageLoad="true" Left="0" Top="0" RestrictionZoneID="zone"></telerik:RadWindow>
            <script>
                Telerik.Web.UI.Window.LightweightView.prototype._resizingHandler = function(resizable, args){
                    $telerik.cancelRawEvent(args.get_domEvent());

                    var edges = this.restrictBounds,
                        bounds = this._getResizeBounds(args),
                        borders = this.resizeHelper.borders,
                        fullBounds = {
                            x: bounds.x - borders.left,//originally, subtract
                            y: bounds.y - borders.top,//originally, subtract
                            width: bounds.width + borders.horizontal,
                            height: bounds.height + borders.vertical};
                    //debugger
                    //console.log(fullBounds);
                    //changing the direction in which borders are counted above (+ or -) changes the behavior and the potential issues
                    //if you subtract from the position, resizing will not be available next to the top/left border of the restriction zone
                    //if you add to the position, resizing will be available but the user can resize in the direction of the zone bounds and thus, out of the bounds of the zone, so dragging may become unavailable
                    //also, this will make resizing worse when the window touches the right or bottom of the zone
                    var inContainer = this.window._checkRestrictionZoneBounds(edges, fullBounds);
                    
                    bounds.width = Math.max(resizable.options.constraints.minWidth, bounds.width);
                    bounds.height = Math.max(resizable.options.constraints.minHeight, bounds.height);

                    args.set_cancel(true);
                    if(inContainer && this.touchCount++ > 0)
                    {
                        var style = this.ui.container.style;
                        style.left = bounds.x + "px";
                        style.top = bounds.y + "px";
                        this._setWidth(bounds.width);
                        this._setHeight(bounds.height);

                        this._currentResizeBounds = bounds;
                    }
                }
            </script>

WORKAROUND 2:
Add this to the resizeEnd and dragEnd events of the RadWindow to try and have it never touch the sides of the restriction zone at all.

				function keepThisWindowInBounds(sender) {
					if (!sender.isMinimized() && !sender.isMaximized()) {
						var position = sender.getWindowBounds();
						var rzRect = document.getElementById(sender._restrictionZoneID).getBoundingClientRect();
						// note rzRect height and width are both 1px bigger than the rzElement clientWidth and clientHeight
						// check width and height
						if (position.width > rzRect.width - 3) {
							position.width = rzRect.width - 3;
							sender.set_width(position.width);
						}
						if (position.height > rzRect.height - 3) {
							position.height = rzRect.height - 3;
							sender.set_height(position.height);
						}
						var needToMove = false;
						if (position.x < 1) {
							needToMove = true;
							position.x = 1;
						} else if (position.x > rzRect.width - position.width - 2) {
							needToMove = true;
							position.x = rzRect.width - position.width - 2;
						}
						if (position.y < 1) {
							needToMove = true;
							position.y = 1;
						} else if (position.y > rzRect.height - position.height - 2) {
							needToMove = true;
							position.y = rzRect.height - position.height - 2;
						}
						if (needToMove)
							sender.moveTo(position.x, position.y);
					}
				}

Please create a method that will convert the old expressions to new format and make them re-usable again.

One workaround is to remove nodes that are not visible, e.g., in the Page_Load event:

RadNavigation1.Nodes.RemoveAll(x => !x.Visible);

Another workaround is to remove the HTML of hidden nodes. Note that this will not affect the nodes collections and they will still be present. Invoking operations or methods on such removed nodes can cause errors.

			<telerik:RadNavigation runat="server" ID="RadNavigation1" OnClientLoad="OnClientLoad">
				<Nodes>
					<telerik:NavigationNode Text="first"></telerik:NavigationNode>
					<telerik:NavigationNode Text="second" Visible="false"></telerik:NavigationNode>
					<telerik:NavigationNode Text="third"></telerik:NavigationNode>
				</Nodes>
			</telerik:RadNavigation>
			<script>
				function OnClientLoad(sender, args) {
					var nodes = sender.get_allNodes();
					var indicesToRemove = [];
					for (var i = 0; i < nodes.length; i++) {
						if (nodes[i].get_element().style.display == "none") {
							$telerik.$(nodes[i].get_element()).remove();
						}
					}
				}
			</script>

Using the set_enabled() method of the NumericTextBox doesn't disable/enable the TextBox properly:

<telerik:RadCheckBox runat="server" ID="CheckBox1" OnClientCheckedChanged="onClientCheckedChanged" Text="Enable/Disable" AutoPostBack="false" />
<telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" />  

function onClientCheckedChanged(sender, args) {
    let numericTextBox = $find("<%= RadNumericTextBox1.ClientID %>");
    let isChecked = args.get_checked();

    numericTextBox.set_enabled(isChecked);
}

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>
