Version 2019.1.219

I've been receiving the above exception on my grids when they're initially filled with their first page of data and on first call to BestFitColumns.

When tracing into decompiled source, the error is thrown on the function in StretchVirtualGridColumnLayout.cs

stretchableColumns are null at this moment which is what's throwing the exception.

Investigating further by placing some break points, the above function is being called before the function "public override void CalculateColumnWidths(SizeF availableSize)" which actually generates the stretchableColumns list.

Im sorry, but I can't include a sample project at this time as the code is too complex.

The grid.OnCellValueNeeded event drives obtaining the data.

I'm not sure where I should call the BestFitColumns method. I am receiving the exception in the OnCellNeeded and OnCellFormatting events on the first call.

Can you advise please?

Hi all,

I've got a question about the scheduler: Is it possible to change the position of the ruler and the day/group header? I need to show the day header (with grouping) on the vertical axis and the ruler on the horizontal axis. Is that possible?

Best regards

Markus

Hi,

I have DataEntry with Dock=Fill, is it possible to "repaint" or "redraw" DataEntry after changing form's size, so controls width corresponds form width?

Thanks

Hi all,

I have C# class called EventHandler that looks like this. StartTime and EndTime both represent the number of seconds since the start of its "parent", which is basically just a list of Events.

I'm trying to use RadGanttView to display the parent, (i.e. a List<Event>), but since StartTime and EndTime are both relative and don't have specific dates, I'm not sure where to begin. Values are both also typically below 5 seconds. Can anyone point me in the right direction?

Thanks in advance!

Hi, I try to copy/paste merged cells, when right click appears a menu with copy/paste options, when copy a cell or range of cells anything is wrong, but when paste the cells appear a popup that say "Cannot change part of a merged cell." Anyone know about this?

Thanks

Hello everyone.

     When I use the RadGridView control, I want to add data to the table that can be entered into four decimal places, but when the data is entered,

 it automatically rounds to save two decimal places; I want it to show how to solve multiple decimal places;

Create new Word-inspired project. Add the event handler below:

If document is not protected then user cannot enter the footer, either by menu or by double-click. If the document is protected (menu Review > button Protect Document) the user cannot edit the footer (as document is protected), nor can they enter it by menu (Insert > Footer), but they can still enter it by double-click. Is there a way to prevent them even from entering the footer by double-click when the document is protected?
