In my serialize function, the function handling the date is decorated as [XmlElement(DataType = "date")] and I thought that the date would be serialized as yyyyMMdd. It looks like it comes out yyyy-MM-dd. On my OS, the format for a date is 05/27/2020. How would I serialize this to be yyyyMMdd?

I am trying to use the AppointmentCalendarImporter to import iCal files exported out of Outlook (using Office Pro Plus 2016). This works quite well except the CATEGORIES from the .ics file are not importing.

 

It appears that the problem is that Outlook is exporting just the category name like this:

CATEGORIES:Personal

 

However, the importer is looking for something like this (got this example from using the Exporter):

CATEGORIES:DISPLAYNAME==Personal&CATEGORYNAME==Personal&

 

Is there a way to get the Outlook format to load?

 

Thanks!

Hi

I am using a GridView containing 2 or 3 lines of data.I have to hide and show some lines related to the condition

But when I hide the row, there is an empty space (possibly a row with no data)

This way I hide the line (I tried both Collapse and Hidden)

  GridView1.GetRowForItem(GridView1.Items[rowIndex]).Visibility = Visibility.Collapse;

How can I completely hide the Grid row?

Hello,

I would like to export my RadGridView to Pdf using the PrintPreviewControl and RadSpreadsheet. To create the workbook I use the ExportToWorkbook method like so:

book = grid.ExportToWorkbook(new GridViewDocumentExportOptions()
{
    ShowColumnFooters = grid.ShowColumnFooters,
    ShowColumnHeaders = grid.ShowColumnHeaders,
    ShowGroupFooters = grid.ShowGroupFooters,
    AutoFitColumnsWidth = true,
    ExportDefaultStyles = true
});

and I style the cells like this:

CellStyle normalStyle = book.Styles["Normal"];
normalStyle.BottomBorder = cellBorder;
normalStyle.IsWrapped = true;
normalStyle.RightBorder = cellBorder;
foreach (Worksheet worksheet in book.Worksheets)
{
    CellRange used = worksheet.UsedCellRange;
    worksheet.Cells[1, used.FromIndex.ColumnIndex, used.ToIndex.RowIndex,
    used.ToIndex.ColumnIndex].SetStyleName("Normal");
}

 

This works fine until I have columns with very long text (with whitespaces) that won't fit on one line (neither portrait nor landscape orientation). I tried to use text wrapping on the cell style by setting the IsWrapped property to true, but this does not yield the desired result. Also "AutoFitColumnsWidth = true" does not seem to effect my columns either.

I also witnessed a strange behaviour concerning columns that are at the end of my GridView where I have to scroll to see them on screen.

When I show the PreviewControl before I scrolled to those columns, I get a different output than when I previously scrolled to those columns.

For better understanding, I attach three pictures of the results I get.

Any help would be appreciated.

Best regards

When I click on the EBS attribute, the window becomes unresponsive and it looks like it is shown in the gif picture.

Is there too much data?

How to optimize the pivot grid?

Secondly, I want to know how to customize the date string format

Hi Telerik Support Team,

I am facing trouble in RadGridView's width which gets increased when I add dynamic columns and their column group headers as per business requirement and at run time only I am removing dynamically added columns and column group headers but the width of the RadGridView never decreased and it does not look good of having grid without any columns on right hand side with horizantol scroll bar.

I hope someone will support me on this trouble.

Thanks

Hi,

I've got an application that is randomly crashing and it seems to be something with the xaml.

See below for the stack trace from the application - it doesn't seem to always happen. It's using implicit themes, I can't remember which one but its a mobile version. Is their a problem with my app or is it the xaml?

Tell me how to redraw the graph without blinking.

Now after SetValue() "No series added" is displayed first, then a new series.

Hallo,

I use DragDropManager to drag & drop items between RadListBoxe A and RadListBox B. It works good. But it will cause the program crashed when I try following:

Because the RadListBox B is not allowed to have TWO items on the same time, so existing item must be "swap" by new one. I remove the existing item and replaced by new one via code. It works good only when it drops under existing item. And, when I drop the new item before the existing item, the program will be crashed by NullReferenceException,  I found the exception caused by  DragDropBehaviour<TSTate> class. See screenshots provided.

Please, solutions, urgent.

Tam
