If anchor links of GridButtonColumn do not define a text links are still rendered and screen readers read their href attribute. Anchor links with no text could define an attribute area-hidden="true".

In the RadEditor we have the NewLineMode set to Div
We are also using a ToolsFile xml document to control the tools available in RadEditor.
The problem is the InsertParagraph tool now inserts <div> tags instead of <p> tags.
We want to keep the NewLineMode behavior as DIV while still having a tool that can insert a paragraph (i.e. a <p> tag).

To replicate this problem:

On the RadEditor demo page, first set "NEW LINES AS" to "Divs".
Then, in the editor content area just above the "Destinations" table, Type in three lines:

If you then toggle to the HTML tab, you will see that the Comment1 line is (incorrectly) bracketed by a <p> tag while the Comment2 and Comment3 lines are (correctly) bracketed by <div> tags.

Next, go back to the Design tab and position yourself at the beginning of the Comment3 line then click the [Insert Paragraph] button.

In the newly inserted "paragraph" type "Comment2b".

If you then toggle to the HTML tab you will see that Comment2b is incorrectly bracketed by a <div> tag.  It should be a <p> tag.

Hello guys,


We've faced an issue with menu on several RAD controls when running on MacOS 10.14.x (Mojave) with FireFox 66.0.x (Quantum).

Using touchpad or mouse, when right clicking for context menu, it just flashed and doesn't stay open: it opens and then suddenly closes.

We are using Telerik Asp.Net Ajax version 2017.2.503.40 but it can be also replicated on your demo version:

Not sure if you can provide a fast workaround for this but I just wanted to let you know.

I've checked for some open cases before creating this thread and hope I didn't duplicate something. Please move/close it if necessary.

When the RenderMode of RadGrid is set to Mobile and UniqueName is different from the DataField then trying to Ungroup an item, it throws an exception: Object reference not set to an instance of an object

I have a few instances where I need OnClientSelectedIndexChanging inorder to stop the listbox selectedIndexChanged event from posting back in certain cases. In those cases I stop it from posting back by setting the e.set_cancel(true);

function CheckForListBoxReorder_OnClientEvent(sender, e) {
    if (ListboxReordered()) {
        alert('Please save changes to the bus order.');

This works very nicely, but I'm getting many errors because although it looks like it's still selected to the proper row in the listbox the selectedIndex is now -1.

RadCodeBLock and RadScriptBlock is not able to handle the server tags for all case scenarios, hence RadAjaxManager throws the exception mentioned in the title.

Using CommandItemTemplate (Grid - Command Item) for Editing DetailTable records and selecting an item after filtering or from another page, one item from the first page is put for editing instead. Open the attached GIF animation (EditSelectedEditWrongItem.gif) to see it in action.


Currently the workaround we offer is to handle the EditSelected command manually for all the DetailTables Except for the Master.


Grid markup:


        <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="100%" PageSize="3"
            <MasterTableView Name="MasterTable" AutoGenerateColumns="true" DataKeyNames="OrderID">
                    <telerik:GridTableView Name="ChildTable" DataKeyNames="OrderID" AutoGenerateColumns="true" CommandItemDisplay="Top">
                            <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" CssClass="btn btn-default">Edit Selected</asp:LinkButton>
                <Selecting AllowRowSelect="true" />


C# - ItemCommand


    protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
        // Logic applies for all the tables (detail tables) which are not named "MasterTable"
        if(e.Item.OwnerTableView.Name != "MasterTable" && e.CommandName == RadGrid.EditSelectedCommandName)
            e.Canceled = true;

            GridTableView detailTable = e.Item.OwnerTableView;

            if (detailTable.OwnerGrid.SelectedIndexes.Count == 0)

            foreach (GridDataItem selectedItem in detailTable.OwnerGrid.SelectedItems)
                selectedItem.Edit = true;



VB - ItemCommand

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As GridCommandEventArgs)
    If e.Item.OwnerTableView.Name <> "MasterTable" AndAlso e.CommandName = RadGrid.EditSelectedCommandName Then
        e.Canceled = True
        Dim detailTable As GridTableView = e.Item.OwnerTableView

        If detailTable.OwnerGrid.SelectedIndexes.Count = 0 Then
        End If

        For Each selectedItem As GridDataItem In detailTable.OwnerGrid.SelectedItems
            selectedItem.Edit = True

    End If
End Sub

ImageEditor keeps in the undo stack a reference to the last written text, but not last inserted one. 


Steps to reproduce:

1. Open
2. Click the add text tool and insert "One"
3. Click the add text tool and insert "Two"
4. Click the add text tool, write "Three" and cancel/close the dialog
5. Click "Undo"
6. Click "Redo"
Result: The last written "Three" string is inserted instead of the expected "Two"

If you put a radspreadsheet inside a radtabstrip with multipage, the controls do not render properly.

In my scenario, I have a tabstrip embedded within a tabstrip, and a grid in the nested tabstrip.  That works fine.  Once you put a spreadsheet control in the multipage, the controls do not render properly. 

However, I was able to reproduce the results with the first scenario above, which is the most simple.

The RadCloudUpload doesn't handle correctly situation, when the communication between client and server becomes disconnected - the client side doesn't get notified (the upload keeps spinning).
All the details and steps to reproduced are in the following thread:

When I load the radspreadsheet from an excel file, the foreground color is not loaded.

A workaround is to use the Kendo Spreadsheet widget directly which imports fore color:

Repro steps 
    go to
    add some text with specific fore color
    save the excel file
    import the excel file

Expected: there is no change

Actual: the fore color is not imported. Also, font size changes, but see the related item for that

The default font size on the client is not saved explicitly on the Excel file, so the Excel defaults take over (11px Calibri), so upon subsequent import all cells will have that font.

Steps to repro:

    go to
    export the file
    import the file

Expected: nothing changes

Actual: all cells are 11px Calibri

<telerik:RadMaskedTextBox ID="txtCountryDigits" runat="server" SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="50px" Mask="+###" ValidationExpression="+\d{1}.d{1}.d{1}" MaxLength="4" />
<telerik:RadMaskedTextBox ID="txtPhoneNumber" runat="server" SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="116px" Mask = "(###) ###.####" ValidationExpression = "\(\d{3}\) \d{3}\.\d{4}" />
<telerik:RadMaskedTextBox ID="txtExtension" runat="server"  SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="100px" Mask="x##########" MaxLength="11" />

This only affects the Edge browser as far as I can tell.

The Country Digits and Extension only allow one character to be entered when the MaxLength is set equal to the number of characters in the mask.  You can only enter 1 character if you tab into the control.  Click on the control with the cursor does not allow the entry of any digits.   Removing the MaxLength property allows entry of the full input.

The lines shifts badly after line 10 

You think you are on line 17  but the cursor is on line 16.  Very annoying bug for those using this control.  Please fix and give us an update.

Look the attached file.

I skipped the 3rd quarter 2016 update (2016.3.1027) for my copy of Telerik UI for ASP.NET.AJAX, since we were in code lock down at that time. 

 Later i installed the 4th quarter version (2016.4.1021.0)

Now, I still get a notice to install the previous version  (2016.3.1027) that I skipped.

That's annoying, and probably not possible. Right?

Is there anything we can do about this situation?

Thanks in advance
