If you have two RadGridView controls and you want to export both of the grids to a common file on two different sheets, it is suitable to use FileExportMode.NewSheetInExistingFile. However, when using the export overload to a stream doesn't respect the ExportMode.

Workaround: use exporting to a file:

            string exportFile = @"..\..\exportedData.xlsx";
            GridViewSpreadStreamExport spreadStreamExport = new GridViewSpreadStreamExport(this.radGridView1);
            spreadStreamExport.FileExportMode = FileExportMode.NewSheetInExistingFile;
            spreadStreamExport.ExportVisualSettings = false;
            spreadStreamExport.RunExport(exportFile, new SpreadStreamExportRenderer());

Hallo,

I was using "Controldefault" theme and I got such an error message on laptops and desctops with smaller resolution when pointing to the gridview control:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

At the same time on desctops with full HD everything was OK. I solved my problem selecting "Windows7" theme but I don't think it is a normal situation so I decided to inform You.

I use Visual Studio 2019 but I was unable to choose it from the list to finish the ticket.

Run the application at 150% and maximize the form. You will notice that with R3 2020 the split container overlaps with the status strip at the bottom:

Workaround: instead of setting the Anchor property to all sides, set the Dock property to Fill.

To reproduce:
1. Add an image column and set wider columns than the images.
2. Group the grid(note that by default the image alignment is center).
3. Export using GridViewSpreadExport
4. The images in the exported file are not centered in the cells.
Note that the issue is not reproducible when there are not groups in the grid. 

Hello,

Just in case you weren't aware of it, there is some code in RadTextBoxControlElement with what seems like an obvious typo, openting instead of opening.
This is from its API page:

Submitted on customer behalf:

We are currently using version 2017.3.1017.40 and noticed an issue with the display of the RadSplitButtonElement in combination with the theme Office2010Blue.
When we disable the RadSplitButtonElement, or more precisely the ActionButtonElement in the DropDownEditorLayoutPanel, it does not display as disabled in the Office2010Blue theme.
In other themes (e.g. Office2010Silver) it does show as disabled.

When trying the latest version (2020.2.616.40) we still get this behaviour, see example below:

It appears similar to the issue mentioned in https://feedback.telerik.com/winforms/1370576-fix-radcommandbar-some-of-the-elements-in-the-control-are-not-rendered-as-disabled-with-office2010blue-and-office2010black-themes

Hi,

I am trialing version 2020.2.504.40 from 2017.1.221.40 and have found an issue converting my current project. Before upgrading I need to get this resolved if you could help please?

If you:

• Add a Telerik form to a new WinForms project
• Set FormBorderStyle = Windows.Forms.FormBorderStyle.None
• Set WindowState = FormWindowState.Maximized
• Show the height and width of the form, i.e. in Me.Resize, put Me.Text = "Width: " & Me.Width & ", Height: " & Me.Height

I have a monitor of 1920x1080. When the form is resized it shows a size of 1934x1094. I have tried setting Me.AllowTheming=False (no avail) and also tried in form Properties > FormBehaviour > AllowTheming=False (but to no avail).

The form size works as expected in 2017.1.221.40.

Kind regards,

Matt

I'm trying to initialize RadControlSpyForm in a .NET 2.0 application and it throws the following exception:

System.InvalidCastException: 'Unable to cast object of type 'System.Windows.Forms.SplitContainer' to type 'System.ComponentModel.ISupportInitialize'.

I did some research, and I found that since SplitContainer doesn't inherit from System.ComponentModel.ISupportInitialize until .NET 4.0, this message shows up in solutions where a project is downgraded from .NET 4.0, but the Form designer isn't regenerated to remove the SplitContainer cast to ISupportInitialize to call BeginInit() and EndInit().

To reproduce: 

Workaround:

radCheckBox2.ButtonElement.Font = new Font("Segoe UI", 20, FontStyle.Regular);

How to reproduce: 

this.radDiagram1.RoutingService.Router = new Telerik.Windows.Diagrams.Core.OrgTreeRouter() { TreeLayoutType = Telerik.Windows.Diagrams.Core.TreeLayoutType.TipOverTree };

this.radDiagram1.RouteConnections = true;

Hi Dess,

I have encountered some other issue here. text of the button is not displaying in this case.

I have set DrawText property as true, UseCompatibleTextRendering as true and TextImageRelation as true. still the text is not displaying only the image is showing. Could you please go thruogh the same project again

attaching the previous link https://feedback.telerik.com/winforms/1480197-event-not-firing-in-commandbar-button-in-radcommandbar-button

Hi Support team,

Please find new link: 

https://drive.google.com/drive/folders/1TF4VG7vrJF6cQykWvvW63zKxdMLYHMwE?usp=sharing

Please refer to the attached sample project:

Workaround:

        Me.RadImageButtonElement1.ButtonFillElement.GradientStyle = GradientStyles.Solid
        Me.RadImageButtonElement1.ShowBorder = False

Just add an image in the editor and try to click on it
