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

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

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.

Scheduled for 2025 Q2 (May)
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);
					}
				}

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();
						}
					}
				}

In RadEditor when specifying WordIgnoreOptions="None", I would expect that "THe" would be flagged as a misspelling, but it is not. It appears the WordIgnoreOptions is being ignored.

We have the latest update for Ajax installed today and have found an issue with the RadSpell control. If you type a value of 'tha' into a textbox/text area control that spell check will target, you will get an error 'Uncaught SyntaxError: Unterminated string in JSON' error in the console. This is able to replicated within the demo page of the Spell control.

https://demos.telerik.com/aspnet-ajax/spell/examples/overview/defaultcs.aspx?_gl=1*19wdrka*_gcl_au*NTA5NTg2MDEuMTc0MDYwNDU5NQ..*_ga*MjA4NzU2NTg4MC4xNzQwNjA0NTkx*_ga_9JSNBCSF54*MTc0MDYwNDU5MS4xLjEuMTc0MDYwNjI5Mi42MC4wLjA.

Remove the text in the first textbox in this page and replace it with 'tha' and in the console you will see the error shoot off.

I am experiencing an issue in the Telerik Rad Editor where, after copying and pasting a long sentence in a single line, if I apply bold formatting to a word and place the cursor at the beginning of the bolded word, pressing Enter results in an empty line being inserted between the text. This behavior is reproducible on the Telerik webforms editor demo site as well.

I would appreciate any guidance on how to resolve this issue. Thanks in advance.

Hello All,

I'm using a couple of Radbuttons to enable users to download some forms (in Word). This has stopped working in Chromium based browsers for some reason (new Edge, Chrome). It still works in Internet Explorer. No errors in the browser DevTools and no error on the server either.
It also does not work in Cassini (VS2017).

Not sure where to go from here - can anyone confirm/deny?

TIA - Marcus.

<telerik:RadButton ButtonType="LinkButton" RenderMode="Lightweight" ID="btnName" runat="server" Text="Button Text" CssClass="TemplBtn" NavigateUrl="~/assets/someform.docx">
         <Icon PrimaryIconCssClass="rbDownload" />

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.

Hi Telerik Team,

I have encountered a strange issue while working with RadEditor in Track Changes mode, specifically when editing tables. When deleting content inside a table cell, the entire cell behaves abnormally—either disappearing visually or causing layout disruptions. I have attached a screenshot to illustrate the issue.


Steps to Reproduce the Issue:

  1. Enable Track Changes mode.
  2. Insert a table with at least 3 columns and multiple rows.
  3. Type some content into different cells.
  4. Delete the content inside one of the table cells.
  5. The cell appears to be deleted or behaves unexpectedly instead of just removing the text inside.
