Hi

I have a RadPropertyGrid, being defined as:

       <telerik:RadPropertyGrid Item="{Binding ObjectBound, Mode=OneWay}" Width="300" Name="propertyGrid2"
                                 Grid.Column="1"
                                 VerticalAlignment="Stretch"
                                 VerticalContentAlignment="Stretch"
                                 NestedPropertiesVisibility="Visible"
                                 AutoGeneratePropertyDefinitions="True"
                                 SelectionMode="Multiple"
                                 PropertySetMode="Intersection"
                                 telerik:PropertySet.ShouldAddNullForNonMatchingValues="True"

where I would like to bind 0...n items

Let's say all of those items belong to the class Car

  public class CarEngine
    {
        public int PowerKW { get; set; }
        public int DisplacementCCM { get; set; }

    }
    public class Car
    {
        public Car()
        {
            Engine = new ();
        }
        public string Manufacturer { get; set; }
        public string Color { get; set; }
        public CarEngine Engine { get; set; }

    }

In the code behind I have a property to bind to the PropertyGrid

public object ObjectBound
        {
            get;
            set;
        }

and will create the items like this:

  Car c = new Car();
            c.Manufacturer = "Honda";
            c.Engine.PowerKW = 110;
            c.Engine.DisplacementCCM = 1799;
            c.Color = "black";


            Car c2 = new Car();
            c2.Manufacturer = "BMW";
            c2.Engine.DisplacementCCM = 2199;
            c2.Engine.PowerKW = 150;
            c2.Color = "black";

            List<Car> list = new();
            list.Add(c);
            list.Add(c2);

now first, I will bind just one car instance to the RadPropertyGrid:

            this.ObjectBound = c;

Here I can expand the nested engine instance and can write to each field which is absolutety perfect!

Then we have a second use case where I would like to bind to the list with two cars and get their common attributes while differerent properties will be displayed empty:

      this.ObjectBound = list;

Therefore I had choosen "Intersection" for the propertysetmode of the RadPropertyGrid

For the primitive Attributes Color (shared between both cars) and Manufacturer (different) that will work just fine. 

But as one can see the nested Attribute "Engine" cannot be set as it not able to be expanded! I'd like to set e.g. a common displacement for both of the two cars. How can I realize such a behaviour as it is required from business?

thanks!

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.

I have issue at WPF  Telerik.Windows.Controls.GridView

I created new columns (GridViewExpressionColumn) the names are "CalculatedColumn" at RadGridView and see the result as at image 

I would like to get the data of the columns from RadGridView, and to create from this column the list of values 

for example:

on first column I would to get all Booleans values as list

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?
