Hello,

I have had to reinstall all Visual Studio versions after some strange behavior, installation was somehow corrupted, VS installers haven't seen any VS versions installed (but they was working almost normally), so I have had to reinstall it, uninstall it manually by InstallCleanup.exe first, and then install VS2019 and VS2022 again. So much for context.

I have installed Telerik for WinForm then and I don't see any Telerik controls in toolbox. I reinstalled Telerik twice, also tried to use Toolbox Configurator, selected .NET4.0 version, but without success. I have the same problem on both VS2019 and 2022. Can you help me please?

        public void pastPanelInit()
        {

            var threadParameters = new ThreadStart(initSpreadSheet);
            var thread2 = new Thread(threadParameters);
            thread2.SetApartmentState(ApartmentState.STA);
            thread2.Start();
            //thread2.Join();

        }


        private void initSpreadSheet()
        {

            if (pastTabCalender.InvokeRequired)
            {
                pastTabCalender.Invoke(new Action(() => initSpreadSheet()));
            
            }
            else
            {
                spreadSheet = new RadSpreadsheet();
                spreadSheet.Dock = DockStyle.Fill;
                spreadSheet.Anchor = AnchorStyles.Top | AnchorStyles.Left;
                spreadSheet.Workbook.Worksheets.Add();
                pastTabCalender.Controls.Add(spreadSheet);
            }
        }

Im having some trouble adding a spreadsheet to my RadPageViewPage since the spreadsheet requires to be on a thread. This still gives me 'Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on.'.

Is there anyone that could explain what im doing wrong here? Thanks.

 

Edit. Updated the code a bit and this gives me that it requires to be on the STA thread. Its something im not understanding with these threadings in c#.

Hey, how can I skip the ViewCellFormatting event while the grid is getting new data?

Maybe there's some property I can check before continuing formatting? I have two interdependent grids and would like to "pause" this event whenever any of them is reloading...

I use telerik UI for WinForms project(not WPF) How to prevent auto close of RadContextMenu when user clicks on item on it? Now, after mouse click on any item, it closes. In WinForms there is ContextMenuStrip.AutoClose property to prevent autoclosing. Is there analogue of the property on Telerik RadContextMenu?

Thanks

I drew an example in the picture.
The format of the data table read from db is shown on the left.
I want to show this on the grid and zoom in
Grouping does not show column information in the row that is being expanded/reduced, but I need information in all rows.
I want to express it like BOM.
I want to expand/reduce to a specific key flexibly according to the column of the table I'm reading, but I don't know what to do.

Hi,

I am trying to create a PDF Table but I  am missing one or more libraries that I should reference. The code fragment I am trying is as follows:

Table table = new Table(); TableRow firstRow = table.Rows.AddTableRow(); TableCell firstCell = firstRow.Cells.AddTableCell(); 

Block block = firstCell.Blocks.AddBlock(); 
block.InsertText("Testing"); 

Thanks
