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">

</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.

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.

When using:

Value = "(null)"
Text = "(no user)"

as item in the ListBox, the filter must work correctly, and after opening the menu the item should be checked if previously filtered.

Additionally if the item have NULL value instead of "(null)" The visible value must be localized. 

The Table Wizard dialog, the Table Properties tab shows Cell Padding and Cell Spacing fields, but this fields can only apply values. If you edit them through the HTML mode or the Properties Inspector module, the fields in Table Properties dialog will not be updated.

Moving of folder from the tree to the grid works, but event is not raised. Also, there is no other suitable event that handles the situation. 

The following patch will raise the event, but  you should make sure to remove the override once the bug is fixed: 

<telerik:RadFileExplorer RenderMode="Lightweight" runat="server" ID="FileExplorer1" EnableCopy="true"
    OnClientMove="OnClientMove" OnItemCommand="FileExplorer1_ItemCommand" >
    <Configuration ViewPaths="~/Images" UploadPaths="~/Images"
        DeletePaths="~/Images"></Configuration>
</telerik:RadFileExplorer>     
 
<script>
    var origFunction = Telerik.Web.UI.RadFileExplorer.prototype._onTreeNodeDropping;
 
    Telerik.Web.UI.RadFileExplorer.prototype._onTreeNodeDropping = function (sender, args) {
        origFunction.call(this, sender, args);
        var destNode = args.get_destNode();
        if (!destNode) {
            var destElement = args.get_htmlElement();
            if (!destElement) return;
            var gridElement = this.get_grid();
            var grid = gridElement != null ? this._isOverElement(destElement, gridElement.get_id()) : null;
            if (grid) {
                var isCopying = this._enableCopy && args.get_domEvent().ctrlKey;
                var eventName = isCopying ? "copy" : "move";
                var args2 = new Telerik.Web.UI.FileExplorerEventArgs(this.get_tree().get_selectedNode(), this.get_currentDirectory());
                this.raiseEvent(eventName, args2);
            }
        }
    }
 
    function OnClientMove(sender, ev) {
        // Do something
    }
</script>

There is a bug in the editor when using the image manager to insert an image after creating a new image.  This is recreated on the live demo site - http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

1. Open the image manager in the editor.
2. Click on an image editor after selecting an image.
3. Use the resizing tool to resize and save a new version of the image. 
4. Once the save is made, both images (the original and the newly created) are selected and when you click insert, both images will be inserted.

The manually entered value of RadDateTimePicker is replaced with the original one in Batch Edid mode in iPad.

To reproduce this incorrect behavior add a new 

<telerik:GridDateTimeColumn HeaderText="Start Date" UniqueName="StartDate" DataField="StartDate" DataFormatString="{0:MM/dd/yyyy}">
            </telerik:GridDateTimeColumn>

column in the Batch Edit demos of RadGrid and test under iPad. 

Tap over RadTextBox, enter some new date and press Go/tap out and you'll see the problem.
