Hello,
Our application has a requirement to automatically log a user out after a period of input inactivity, e.g. keyboard or mouse events for security reasons.
When we automatically log out a user, we also want to close any open modal dialogs in our application, including any modal dialogs open in the Telerik ReportViewer - such as the Export / Print dialogs.
Is there a way for cancel/close these modal dialogs?
I looked at the specific events such as ExportBegin as it provides a way to cancel the export, but I need a way to close the dialogs at any time not just at the specific time the export starts.
Thanks,
Canice.

In WPF there is an export icon looks like a diskette. One can specify what type of export. PDF, Exel etc. then a call to Windows "Save As" dialog box.
My question is there a way to populate/specify the file path in the "Address bar"?
Some kind of registry or something. The end user can of course alter the destination if they wish.
How can I repeat certain lines on each page of a workbook?
WorksheetPageSetup worksheetPageSetup = worksheet.WorksheetPageSetup;
worksheetPageSetup.PaperType = PaperTypes.A4;
worksheetPageSetup.PageOrientation = PageOrientation.Landscape;
worksheetPageSetup.FitToPages = true;
worksheetPageSetup.CenterHorizontally = true;
worksheetPageSetup.PrintTitle ...Assignment via PrintTitle does not work.

Hello,
How can I select all expanded/visible rows in a radgridview control, which have been grouped and possibly filtered, even if the rows fall out of view of the window container?
I have a window that contains a radgridview and a button that is outside of the grid which selects or deselects all visible rows in the radgridview. An end user may add multiple groupings and filters. There is a lot of data in the item source, at the time of this test over 3 thousand rows. The resulting data display after the end user has made changes will likely exceed the window containers viewable area. when I implemented the line of code below only the expanded row visible in the window was selected. The expanded rows that I had to scroll down to see were not selected. I would like to select all of the expanded/visible rows.
var visibleRows = grdBatches.ChildrenOfType<GridViewRow>();
I have read that ChildrenOfType<T> works on visual elements. In another forum question, the answer stated that the use of visual elements is not advised when working with virtualized controls such as the radgridview.

I get the following error when I try to add a Telerik WPF Form
Project template
Adding a WFP forms triggers this and nothing added?
So I tried a WPF .NET Core template and got prompted for this"
No idea how to proceed ... just trying to create a new project?

Dear Team,
I have a WPF app (vb.net) where i use radgridview. Virtualization is on because we have more hundreds of rows, and in the CELLLOADED event i color the cell backgrounds based on cell content.
The result is something like this: (attached: mapps.jpg)
The customer wants me to create excel output, including the colors. I browsed a lot of forums and i found multiple approaches but the result is always the same. The background is colored, but all column inherits the color of the first row. (attached: excel.jpg)
Sub ExcelExport_Colored(rgv As RadGridView)
Dim workbook As Workbook = rgv.ExportToWorkbook(New GridViewDocumentExportOptions() With {
.ExportDefaultStyles = True,
.AutoFitColumnsWidth = True,
.ShowColumnHeaders = True})
Dim dialog As SaveFileDialog = New SaveFileDialog()
dialog.DefaultExt = "xlsx"
dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", "xlsx", "Excel")
dialog.FilterIndex = 1
If dialog.ShowDialog() = True Then
Dim provider = New XlsxFormatProvider()
Using output = dialog.OpenFile()
provider.Export(workbook, output)
End Using
End If
Dim excelPath2 As String = Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe",
"Path", "Key does not exist")
Microsoft.VisualBasic.Interaction.Shell(excelPath2 & "EXCEL.EXE /e/min """ & dialog.FileName & """", AppWinStyle.NormalFocus)
End Sub
I tried other export options as well, like radgridview.export, radgridview.exporttoxlsx.. all give the same result or worse.
Can you give any advice how to achieve it? I don't insist to the icons, if i could export the data with bgcolors i would be happy already.
Thank you !!
Peter


Hi ,
In one of my wpf window I have two grids. In one grid I only have product name that lists all the products available and another grid i have product details( id, name, price etc.) and there is a add and remove button. If I select one product name add click add then it should add the details to the product details grid and also should be able to remove it. How can I implement it. Do you have any sample code?
Hello,
I am trying to get the GridViewDataColumn after mouse click.
I can notice that radGridView.CurrentCell.Column is updated on left click. So if I perform left click and then right click, the context menu is open and I have reference to the correct column.
But if Ido right click in different cells, the current cell is not updated al I have refence to the old column.
How can I get the GridViewColumn from Cursor position.
I have only the grid, I haven't any mouse arguments.
