I'm using couple of Rad Editor controls in my webpart and using ToolProviderID for performance optimization.
I'm initializing one rad editor toolbar from server side and using the same toolbar to provide other rad editors with their toolbar, Bascially I'm using ToolProviderID attribute to initialize other RadEditors, after doing this the Comments and Track Changes feature stop working although their options are selected in the toolbar.


<telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1" EnableTrackChanges="true" EnableComments="true">
    <TrackChangesSettings Author="AuthorName" CanAcceptTrackChanges="true" UserCssId="reU0" />
    <Tools>
        <telerik:EditorToolGroup>
            <telerik:EditorTool Name="AcceptTrackChange" />
            <telerik:EditorTool Name="RejectTrackChange" />
            <telerik:EditorTool Name="AcceptAllTrackChanges" />
            <telerik:EditorTool Name="RejectAllTrackChanges" />
            <telerik:EditorTool Name="EnableTrackChangesOverride" />
        </telerik:EditorToolGroup>
    </Tools>
</telerik:RadEditor>

I've been trying to upgrade an existing solution to use the latest release version (2019) of the Telerik UI for ASP.NET AJAX and have encountered a major problem with the 'Tool Provider', a technique which is significantly used in my solution.  This same error displays in your own Telerik Demo.  Details are:

 

Description of the issue

Having multiple RadEditors on the same page, and trying the property "ToolProviderID" (to reuse the same floating tool amongst the different editors on the same page), causes a "javascript exception" on the client side.


   
URL of the Demo (Telerik Website)

https://demos.telerik.com/aspnet-ajax/editor/examples/toolprovider/defaultcs.aspx



Exception description

Uncaught TypeError: R.get_canAcceptTrackChange is not a function at c.RadEditor._initializeToolProvider (RadEditor.js:8239) at c.RadEditor.initialize (RadEditor.js:8297) at c.RadEditor.endUpdate (Telerik.Web.UI.WebRe597d4b%3ab25378d2:6) at Sys._Application.endCreateComponents (Telerik.Web.UI.WebRe597d4b%3ab25378d2:6) at Sys.WebForms.PageRequestManager._scriptsLoadComplete (Telerik.Web.UI.WebRe97d4b%3ab25378d2:15) at Sys.WebForms.PageRequestManager.<anonymous> (Telerik.Web.UI.WebRe597d4b%3ab25378d2:6) at Telerik.Web.UI.WebRe597d4b%3ab25378d2:6 at Sys._ScriptLoader._loadScriptsInternal (Telerik.Web.UI.WebRe97d4b%3ab25378d2:15) at Sys._ScriptLoader._loadScriptsInternal (Telerik.Web.UI.WebRe97d4b%3ab25378d2:15) at Sys._ScriptLoader._loadScriptsInternal (Telerik.Web.UI.WebRe97d4b%3ab25378d2:15)
    



How to reproduce the error (on Telerik demo website)

    - Mark the checkbox at the bottom of the page and click on "Update":

(the error can be seem on console, pressing F12)

Exporting an empty RadGrid to XLSX or Biff with ExportSettings-ExportOnlyData="true" and Caption set, throws exception: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Steps to reproduce:

RadGrid markup:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true"
    OnNeedDataSource="RadGrid1_NeedDataSource">
    <ExportSettings ExportOnlyData="true">
        <Excel Format="Biff" />
    </ExportSettings>
    <MasterTableView Caption="My Personalized caption" CommandItemDisplay="Top">
        <CommandItemSettings ShowExportToExcelButton="true" />
    </MasterTableView>
</telerik:RadGrid>


C# - Code behind

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    RadGrid1.DataSource = OrdersTable();
}
 
private DataTable OrdersTable()
{
    DataTable dt = new DataTable();
    dt.Columns.Add(new DataColumn("OrderID", typeof(int)));
    dt.Columns.Add(new DataColumn("OrderDate", typeof(DateTime)));
    dt.Columns.Add(new DataColumn("Freight", typeof(decimal)));
    dt.Columns.Add(new DataColumn("ShipName", typeof(string)));
    dt.Columns.Add(new DataColumn("ShipCountry", typeof(string)));
    dt.PrimaryKey = new DataColumn[] { dt.Columns["OrderID"] };
    return dt;
}

The RecurrenceRule does not have the correct Exceptions when modifying the series. The behavior in Outlook is to clear all exceptions when modifying the series. The behavior in Google Calendar is to consider the exception and modify the recurrence rule accordingly.

Create a recurrence appointment (starts on 20th Feb at 8:00 am, recurring daily), whose recurrence rule will be stored in the database as (Picture 1):

DTSTART:20180220T080000Z
DTEND:20180220T083000Z
RRULE:FREQ=DAILY;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR,SA,SU

Further, I create an exception on 23rd Feb, which changes the start time to 8:15 am. This now, in Addition to inserting a new record for the exception, updates the master's recurrence rule to (Picture 2):

DTSTART:20180220T080000Z
DTEND:20180220T083000Z
RRULE:FREQ=DAILY;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR,SA,SU
EXDATE:20180223T080000Z

So far, so good. Now I edit the master and change its start date to 19th Feb. I expect, that the master keeps the exception for 23rd, but the result is another one. The exception record is kept unchanged as expected! BUT the EXDATE in the master is wrong (Picture 3):

DTSTART:20180219T080000Z
DTEND:20180219T083000Z
RRULE:FREQ=DAILY;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR,SA,SU
EXDATE:20180222T080000Z

Inconsistent Behavior of RadEditor with Ribbon Bar Toolbar for a different type of dropdown toolbar controls.

In RadEditor with Ribbon Bar Toolbar, there are two different types of drop-down control observed.

Type1 includes "Paste" and "Strip All Formatting" 
Type2 includes "Font Name", "Real font size", "Foreground Color", "Background Color", "Apply CSS Class", "Paragraph Style" and "Undo"


Issue1:
In RadEditor with Ribbon Bar Toolbar When "Type 1" Dropdown is opened or expanded and we click on any "Type 2" Dropdown then "Type 1" dropdown is still remain open or expand.

Issue2:
vice versa In RadEditor with Ribbon Bar Toolbar When "Type 2" Dropdown is opened or expanded and we click on any "Type 1" Dropdown then "Type 1" dropdown is still remain open or expand.

Right now the end user can resize the table cells only through the provided interface in the Table Wizard and Properties inspector module. It will be useful this to be enabled as resize handlers directly in the table as it is implemented in the Kendo Editor - https://demos.telerik.com/kendo-ui/editor/index.

Hi,

i would love to have a n option to set the Gallerry to keep the title and text visible when the Gallery is in play mode, until the user pause the gallery or move the mouse out.

a work around was provided to me by Attila, which works fine, but i think it should be a built in property.

 

Thanks a lot,

ilan.

When you have 3 documents with picture, and texts in all - the texts are shows as expected. but when one of them does not have text and title, the loop of the gallery stop showing it for the other pictures.

<telerik:RadImageGallery ID="RadImageGallery1" runat="server">
    <ThumbnailsAreaSettings ThumbnailWidth="140px" Width="140px" Position="Left" ScrollOrientation="Vertical" />
    <Items>
        <telerik:ImageGalleryItem ImageUrl="Images/Yoga.jpg" Title="Title 1" />
        <telerik:ImageGalleryItem ImageUrl="Images/Swimming.jpg" Title="Title 2" />

            <%-- Title container disappears here and will not show up with the rest of the items --%>
        <telerik:ImageGalleryItem ImageUrl="Images/Surfing.jpg" /> 

        <telerik:ImageGalleryItem ImageUrl="Images/Snowboarding.jpg" Title="Title 4" />
        <telerik:ImageGalleryItem ImageUrl="Images/Skiing.jpg" Title="Title 5" />
    </Items>

RadCalendar and RadDatePicker cannot pass the following check by https://achecker.ca/checker/index.php

WCAG 2.0 guideline
Section

1.3 Adaptable: Create content that can be presented in different ways (for example simpler layout) without losing information or structure.
Success Criteria 1.3.1 Info and Relationships (A) 

Check 245: Data table with more than one row/column of headers does not use id and headers attributes to identify cells.

Repair: Add id and headers attributes to table cells so they identify the cells that relate to the headers.

Error Line 597, Column 8:
<table id="ctl00_ContentPlaceholder1_RadDatePicker1_calendar_Top" class="rcMainTable" summary="Table …

Steps to reproduce

Go to https://achecker.ca/checker/index.php

<telerik:RadComboBox runat="server" ID="CB" AllowCustomText="true" HighlightTemplatedItems="true" EnableViewState="false" CheckBoxes="true" EnableLoadOnDemand="true" OnItemsRequested="CB_ItemsRequested" ></telerik:RadComboBox>

Specifically, note that CheckBoxes is true.

In some cases, the combo box's  item's text may have HTML tags in them, but we don't want that HTML to be interpreted, and we're happy that RadComboBox automatically encodes the Item's name.  For example, the Item's text might be <img src=xxx onerror=alert(0)> , and of course we don't want that javascript to run. 

However, we have found a case where the text is not properly escaped, in which case the javascript does run and the alert popup shows.  The error is in RadComboBox.CheckBoxes.js, in the _checkedItemsTextsFitInputWidth function.  That function is passed the comma separated string of all the selected item's text.  This function wants to measure the width of the string, and so it creates a div off-screen, and then pushes the checkedItemTexts string into the div.  If the checkedItemTexts string contains any HTML tags that contain javascript, then that javascript is executed, which can be a XSS attack.

When a RadColorPicker that only has the HSB or HSV palette is made visible or added during an AJAX request, it throws the following error:

Sys.ArgumentOutOfRangeException: Height should be an integer bigger than 1

This is caused by the lack of dimensions while the component is initializing on the client side and, for example, RGBSliders, manages to initialize correctly. The control must either have default dimensions for all modes, or to perform check for undefined dimensions provided by the browser, or both.

A workaround is to add the RGBSliders mode as the first mode so the control can initialize, and use a small JS handler that will switch to the HSB/HSV mode and hide the RGB mode.

Here follows an example that includes the workaround:

<asp:UpdatePanel ID="mainUpdatePanel" runat="server">
    <ContentTemplate>
  
        <telerik:RadButton ID="RadButton1" runat="server" Text="RadButton"></telerik:RadButton>
  
        <asp:Panel runat="server" ID="wrappingPanel">
  
            <%--WORKAROUND PART 1 - add the RGBSLiders tab first--%>
            <telerik:RadColorPicker ID="RadColorPickerStart" runat="server" PaletteModes="RGBSliders, HSB"></telerik:RadColorPicker>
  
            <%--WORKAROUND PART 2
            The script is wrapped in a RadScriptBlock so it gets
            registered and executed after the partial postback. By default, it will not be parsed--%>
            <telerik:RadScriptBlock runat="server" ID="rsb1">
                <script>
                    Sys.Application.add_load(function () {
                        //a panel is used here to make looking for the color pickers added in it easier
                        //you can replace getting the reference to the color picker with any preferred method
                        $telerik.$("[id$='wrappingPanel']").find(".RadColorPicker").each(function (index, elem) {
                            if (elem && elem.control) {
                                var picker = elem.control;
                                setTimeout(function () {
                                    //trigger the internal logic of the control that will switch the tabs
                                    //in this case - the HSB tab is "clicked"
                                    picker._tabClicked({ target: $telerik.$(picker._tabStrip).find("a[title='HSB']")[0] });
                                    //hide the RGB tab
                                    $telerik.$(picker._tabStrip).find("a[title='RGB']").hide();
                                }, 0);//the timeout is needed so the control can initialize before we manipulate it
                            }
                        })
                    });
                </script>
            </telerik:RadScriptBlock>
        </asp:Panel>
  
    </ContentTemplate>
</asp:UpdatePanel>
Protected Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
    wrappingPanel.Visible = True
