Hi Support,

 

please try set the WorkBook to RadSpreadsheet.

Best regards

Fritz

Currently if radSpreadsheet RightToLeft property is set to Yes, only the Formula Bar is affected; RadSpreadSheet and Status Bar are not.

The scale factor is not imported from documents with no information about the selection state.

Add support for creating Tables and applying tables styles (predefined ones or custom).

If a worksheet spans more than one page, you can print row and column headings or labels (also called print titles) on every page to ensure that the data is properly labeled.

Hello,

 

I have a RadRibbonForm with a normal ribbon with no items and a spreadsheet control.

 

I iterate over a datatable and fill the spreadsheet's cell values with the datatable's values

we're talking about a very small size, like 33 rows x 35 columns, and not even all the values are filled in.

 

Unfortunately, there's a very noticeable delay in the spreadsheet, from moving the scrollbars to selecting to changing sheets.. the whole thing feels laggy.

Is this just how it is, or am I experiencing a possible bug?

Could it have anything to do with https://feedback.telerik.com/winforms/1380948-exception-at-runtime-trial-bug ?

 

If that is just how it is, is there anything I can do to make it feel snappier? Disable a theme? Disable some behaviour?

The list data validation rule allows you to restrict the user input to a predefined set of values: https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/data-validation#list-rule
