When search dropdown is open in MultiColumnComboBox and you scroll the page (e.g. by mouse wheel) the dropdown is immediately closed which is quite inconvenient.

Both Combobox and DropDownList keep the dropdown opened when you are scrolling the page.

Could you fix it?
Any temp workaround?

Release R3 2023
The contrast between the colors for the background and the text in the Tooltip of the Chart series is very low (dark background and black text). https://www.screencast.com/t/fhx6937j

The problem is most obvious in the Outlook, Simple, Web20 and Sunset skins. 

Workaround would be  setting the Color property for the ToolTipAppearance to White

Suddenly all my projects tell me to 'Convert to Telerik Web Site' but they all are already are?

All projects are affected. If I try to convert and choose a different skin this seems to affect the installation, but the button 'Convert to Telerik Web Site' is still visible.

Is there a way to fix this?

In R3 2016 SP1 when a RadEditor with RenderMode=Classic is disposed and RadScriptManager is used, a JavaScript error is thrown:
IE:  Object doesn't support property or method 'dispose'
Chrome: Uncaught TypeError: this._contextMenuFunctionality.dispose is not a function

FIXED in R3 2016 SP2 (2016.3.1027)

There are three workarounds:
- Set EnableScriptCombine to false for the RadScriptManager (not applicable when CDN is used)
- OR set RenderMode=Lightweight for the RadEditor (you can do this in the web.config for all control instance in the web app if they do not define the Classic mode exiplicitly)
- OR add the following function override at the end of your page:

			<telerik:RadScriptManager ID="RadScriptManager1" runat="server" >
			</telerik:RadScriptManager>

			<%-- WORKAROUND 1: SET EnableScriptCombine="false" TO RADSCRIPTMANAGER--%>

			<asp:Button ID="Button1" Text="click to postback and break the editor" runat="server" />

			<telerik:RadEditor ID="txtInstructions" runat="server">
			</telerik:RadEditor>

			<%-- WORKAROUND 2: SET RenderMode="Lightweight" TO RADEDITOR--%>


			<%--WORKAROUND 3: ADD THE FOLLOWING SCRIPT TO THE END OF THE FORM--%>
			<script>

				Telerik.Web.UI.Editor.DefaultToolAdapter.prototype.dispose = function ()
				{
					delete this._fakeToolbarParentCreated;
					var toolbars = this._getToolBarElements();
					if (toolbars) {
						for (var i = 0; i < toolbars.length; i++) {
							$clearHandlers(toolbars[i]);
						}
					}
					this._tools = [];
					this._disposeToolbarModeHandlers();
					var wnd = this._toolbarHolder;
					if (wnd && wnd.dispose) wnd.dispose();
					var contextMenuFunctionality = this._contextMenuFunctionality;
					if (contextMenuFunctionality && contextMenuFunctionality.dispose) contextMenuFunctionality.dispose();
					Telerik.Web.UI.Editor.DefaultToolAdapter.callBaseMethod(this, "dispose");
				}
			</script>

We have recently implemented the Signature control into our Web Forms application using the latest version of Telerik UI Controls for Asp.Net Ajax.

We are having an issue where if the signature control isn’t in the main focus when it loads (for example the control is in a tab that isn't initially the main focus) - the signature stroke is distorted.

In addition, when you maximize the signing area - it has the same distorted view.

The issue can be replicated in the OLAP and KPIs Support demo.

Steps to replicate the issue:

  • Add an item to the "Row Fields" by checking the checkbox of the item in the "All Fields" panel
  • Remove the item from the "Row Fields" by unchecking the checkbox of the item in the "All Fields" panel
  • Click the Update button
  • After the PostBack the PivotGrid will display the Item in the "Row Fields" despite it was removed soon after adding it.

Hello

I have an ASP.NET Ajax Telerik Solution (site) that has a web site project and a library project.  The solution was developed almost 8 years ago and so far I've been able to upgrade telerik controls  several times without any problem. Now, when I tried to upgrade the Telerik controls using the Upgrade Wizard Project only shows the class library as you can see in the attached picture.

To replicate this beahavior:

1. Create a new Telerik VB Webform Site
2. Add a Class Library Net Framework project to the solution.
3. Add a reference to Telerik.Web.UI to the Class Library project (optional).
4. Save and close solution.
5. Reopen it and run the Telerik Upgrade Wizard Project.

It only shows the Class Library project ...

The menu commands for Telerik projects sometimes are not visible. The reason why is that the visibility state of the commands is evaluated asynchronously. Depending on the time it takes to evaluate the command state, sometimes the commands are not available when they are queried for the first time.

NOTE: It can be observed in all Telerik products.

When making a partial PostBack while the Combos are inside a RadAjaxPanel, the components initialize in the reverse order, where the last Combo initializes first, the second to last initializes next, and so on. This way, the Child combos can't access the Parent's values as the parent is not initialized at that time.

1.       Visit the RadEditor demo at https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx (I used Google Chrome.)

2.       In the HTML view, replace the entire demo text with

This <strong>strange</strong> thing

3.       In the Design view, place the cursor at the very end of the line, and press Shift+Left repeatedly.

a.       At first it will highlight the final letter correctly.

b.      Then it will UNHIGHLIGHT the final letter!

c.       Then it will begin highlight more letters again starting from the letter BEFORE the final letter.

d.      Then, after highlighting the “e” in strange, it will being UNHIGHLIGHTING starting from the righthand side of the selection!

e.      Then it will highlight left as far as the “s”.

f.        Then it will start UNHIGHLIGHTING from the right again!

g.       Then highlighting the space to the left

h.      Then UNHIGHLIGHTING the space to the left!

i.         Then highlighting to the left as far as the beginning of the line

j.        Then UNHIGHLIGHTING from the right side of the selection!

Pressing Shift+Left and Shift+Right should always modify only one end of the selection, and the other end should always remain where the selection was started. This is how Windows Notepad and virtually all other applications behave.

Steps to reproduce the text highlighting issue:

  1. Go to https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
  2. Delete the content and write a single line
  3. Use the mouse to highlight a portion of text starting at the end (right side) of the text and dragging toward the beginning (left side).
  4. Stop about halfway to the beginning of the text.
  5. Now, while the text is still highlighted, press shift and left arrow to continue selecting. This will work for some time until the highlight gets near the beginning, then, the highlight will start moving from the right side.

When assigning multiple resources and percentages, the first item in list always goes back to 100%.

It saves back to UI correctly but as soon as you leave or refresh page it goes back to 100% on first item and that's what's saved in database.

The online demo has the same code but demo doesn't save at all to test.

See attached screen shots.

Steps to replicate the issue:

  • Set the computer's Time Zone to CST (Central Standard Time) which is UTC -6:00.
  • Enable Daylight Saving
  • Open VS and create a new Page with a DatePicker in it (basic settings)
  • Select the date "4/1/2023" and picking the time "2:00 AM" jumps to "3:00 AM"

Important: for the Time Zone changes to have effect, the Visual Studio solution has to be closed/re-opened.

Due to recent changes to the keyboard accessibility of the RadMenu (i.e. it is now only accessible using the arrow keys instead of moving around using tabs), mega menus are no longer keyboard accessible.

We have designed a mega menu using a telerik RadSiteMap embedded in a RadMenu control, as suggested in the Telerik Demo site: http://demos.telerik.com/aspnet-ajax/menu/examples/megadropdown/defaultcs.aspx

However, this is no longer accessible. Previously, you could open the dropdown by pressing the down button, then move around in the dropdown using tab. Now, however, pressing tab just closes the dropdown.

We need the menu to be accessible in one way or another.

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
