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.

I know its a long shot, but do you have anything that resembles the attached control.

Thank you

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>

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.

When creating and upgrading Telerik UI for AJAX projects to version 2025.1.211 using "InstallFolder" distribution Telerik UI for ASP.NET AJAX references are not added to the project.

Error thrown:
Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: 'maxDate' is not a property or an existing field.

Setup for reproduction:

<asp:ScriptManager runat="server" ID="ScriptManager1"></asp:ScriptManager>

<telerik:RadDateRangePicker runat="server" ID="RadDateRangePicker1" 
MinDate="2022-05-01" MaxDate="2022-05-01">
</telerik:RadDateRangePicker>

When pasting bullet lists from Microsoft Word into the editor, extra leading spaces (&nbsp;) appear in the list items. This causes unexpected indentation and formatting issues.

Before 2025 Q1

In 2025 Q1

After upgrading to 2025 Q1, RadGrid throws the exception: 

Uncaught TypeError: t is not a function

Hi,

Would it possible to build in a text search filter into a Listbox?

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

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 https://demos.telerik.com/aspnet-ajax/spreadsheet/examples/import-export/defaultcs.aspx 
    export the file
    import the file

Expected: nothing changes

Actual: all cells are 11px Calibri
Workaround: Set a default font when the cell font is null
 
public override void SaveWorkbook(Workbook workbook)
{
    string path = "C:\\path-to-output.xlsx";
     
    for (int i = 0; i < workbook.Sheets.Count; i++)
    {
        for (int j = 0; j < workbook.Sheets[i].Rows.Count; j++)
        {
            for (int l = 0; l < workbook.Sheets[i].Rows[i].Cells.Count; l++)
            {
                string fontFamily = workbook.Sheets[i].Rows[i].Cells[l].FontFamily;
                workbook.Sheets[i].Rows[i].Cells[l].FontFamily = !string.IsNullOrEmpty(fontFamily) ? fontFamily : "Courier New";
 
                double? fontSize = workbook.Sheets[i].Rows[i].Cells[l].FontSize;
                workbook.Sheets[i].Rows[i].Cells[l].FontSize = fontSize.HasValue ? fontSize : 12;
            }
        }
    }
    workbook.Save(path);
}
 

I like to add my own buttons in the toolbar, for example to open new Windows, add more text to the description, specify if I like or dislike the picture.
