Greetings,
I have noticed today that the following demo pages are broken when using the latest versions of Chrome & Edge:
https://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/dateaxis/defaultcs.aspx
https://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/pan-zoom/defaultcs.aspx
Each of these have a series of JavaScript errors that prevent the page from working:
RadHtmlChart.js:79 Uncaught SyntaxError: Invalid or unexpected token
at b.RadHtmlChart._parseObject (RadHtmlChart.js:79:46)
at b.RadHtmlChart._configurePlotArea (RadHtmlChart.js:128:47)

Hope this helps ....

On my pageI have a RadGrid with columns containing gross and net ammounts and a RadButton "Gross/Net". By clicking the button the grid shows it columns accordingly. Worked liek a charm.
Then I added aggregates od type "Sum" and still everything worked fine.
After that I added an aggregate od type "Custom" to one of the columns (which calculates and shows everything as it should) but than I lost the button funcionality, clicking it does not switch the columns visibility.
The button does: myGrid.MasterTableView.GetColumn("mycolumn").Display = Not mybutton.Checked.
Also tried: myGrid.MasterTableView.GetColumn("mycolumn").Visible = Not mybutton.Checked

Im using visual studio 2019 to develop an application in asp.net using c#
I have a telerik radgrid and it has a few columns that have text boxes to make it editable.
This works find but when the grid is loaded with data and the rows go to the bottom edge of the webpage you cant edit the text boxes in the last row, like they become readonly. This only happens to the first 5 editable columns the last 3 columns are ok and working.
Ive tried adding a DIV round the grid so the grid doesnt go right to the bottom of the webpage but the same issue occurs when the rows reach the bottom of the DIV.
Thanks

Hi
I have searched the forums and can't see anything that seesm to match my case.
I want to hide a column based on a value set in a settings table. No problem getting the
setting value as true or false, but I can't make the column hidden.
Columns are not autogenerated and the column in question is declared like this
How can this be made visible/invisble from the code behind?
I have tried this below but I think it is applicable only to autogenerated columns.. Anyway it does not do anything.
Thanks for help here!

The tab toolbar items (Bold (B), italic (I), underlined (U), etc.) act like a Tab list (one can be selected), but when we navigate on it, the screen reader announces the role as a link, which is confusing.
Also, with the role link, the user is not getting enough information about which one is currently selected (visually with colour indication). The screen reader announces as 'Bold, link'.
The recording is attached in the zip file.

As you can see from the image, on mobile devices the date ends up breaking and making it impossible to view it completely.
This is my code:
<div class="col-xl-3 col-sm-6 col-md-6 col-xs-12 mb-2">
<span class="EstiloLabelSimples">Data Vencimento:</span>
<telerik:RadDatePicker RenderMode="Lightweight" ID="txtDataVencimentoCadastro" Width="100%" runat="server" />
</div>
I've tried using other RenderMode types, but none of them worked. Could someone help me achieve this responsiveness?

I have a grid full of data, and the data behind is is frequently changing.
When the user picks a row to edit and clicks the edit button, it seems that the grid says "Edit the 5th item in the grid". Of course, during the AJAX postback, the grid loads completely different data, and the record they want to edit is now the 9th item.
Is there any way to have the grid say "Edit item with a key value of 34832" instead of being positional? The only other solution I've come up with is to cache the grid data in session, and if the grid gets an edit command, reload from the cache instead of the database. I'm going to go try to implement that now.

Hi, I am facing the following issues with the Telerik table. Can you please help resolve them?
1. The text is not aligned with the dropdown (Image attached)
2. When we edit the widget > click on the table on a random cell > select Table Properties > The table wizard will always default to the top left cell > This is working as expected.
If you click in the table (not the editor) and select Cell Properties > the wizard will display (highlight) the cell you selected in the table is it expected that when selecting table properties it always default to the left side first box but when selecting cell properties it will show the current cell which we are in.
video link:- https://jam.dev/c/c1cdf56c-53ab-4218-8774-65907b3efd6d
3. Table properties > Select cells (e.g the top three) > Border > Select the bottom > 6 PX > Purple > OK > The preview is not showing the changes we want to apply > the preview is showing only the top left cell
video link:- https://jam.dev/c/88c17904-c758-47ab-949c-d29b4775dc6d
4. Following step 3 > when we navigate the mouse up and down, in the background, we can see only the top left cell with the border we configured. (while initially we selected the top three) > But if now, in the preview page, we will choose the top three > OK >We will see the top three cells showing the design we configured.
video link:- https://jam.dev/c/ba52bff1-7459-44d6-a647-d3eb5cea07f3
5. From the widget/page > select the middle bottom cell (notice it has no styling) > Table properties > Cell Properties > Select the middle bottom cell again > More Cell Styling > Border > Notice that the top row design is inherited > Is this expected?
video link:- https://jam.dev/c/1516e16f-1f7c-4e89-8b19-368edabf5703
5.1 I have observed that when we're in the widget > selecting a cell from the table > clicking on Cell Properties > The top row design is not inherited.
