Hello Support-Team,

I'm using a RadScheduler with a custom ElementProvider. I need some Help with the Elements. I wanted the name element on top and a info box right below using the rest of the free space. I made a screenshot and here is my code for the CustomElements:

class CustomSchedulerResourceHeaderCellElement : SchedulerResourceHeaderCellElement
{

        private readonly StackLayoutElement _container = new StackLayoutElement();
        private readonly StackLayoutElement _subContainer = new StackLayoutElement();
        private readonly LightVisualElement _nameElement = new LightVisualElement();
        private readonly LightVisualElement _infoElement = new LightVisualElement();

        protected override void CreateChildElements()
        {
            base.CreateChildElements();

            _container.StretchHorizontally = true;
            _container.StretchVertically = true;
            _container.Orientation = Orientation.Vertical;
            _container.Alignment = ContentAlignment.TopCenter;
            _container.Padding = new Padding(3);
            _container.Children.Add(_nameElement);

            _nameElement.StretchHorizontally = true;
            _nameElement.DrawImage = true;
            _nameElement.ImageLayout = ImageLayout.None;
            _nameElement.TextWrap = true;
            _nameElement.TextAlignment = ContentAlignment.TopLeft;
            _nameElement.ImageAlignment = ContentAlignment.TopLeft;
            _nameElement.TextImageRelation = TextImageRelation.ImageBeforeText;

            _container.Children.Add(_subContainer);
            _subContainer.StretchHorizontally = true;
            _subContainer.StretchVertically = true;
            _subContainer.Orientation = Orientation.Vertical;
            _subContainer.Alignment = ContentAlignment.TopCenter;
            _subContainer.Children.Add(_infoElement);

            _infoElement.StretchHorizontally = true;
            _infoElement.StretchVertically = true;
            _infoElement.TextWrap = true;
            _infoElement.TextAlignment = ContentAlignment.TopLeft;

            _infoElement.BackColor = Color.FromArgb(128, Color.LightGray);
            _infoElement.NumberOfColors = 1;
            _infoElement.DrawFill = true;
            _infoElement.Font = new Font(this.Font, FontStyle.Regular);

            this.Children.Add(_container);
            this.DrawImage = false;
            this.DrawText = false;
        }

        public override string Text
        {
            get
            {
                InitElements();
                return base.Text;
            }
            set
            {
                base.Text = value;
            }
        }

/* Some more methods for setting the text elements and the image*/
}

I started with only one container, but adding a subcontainer didn't do the trick. Hope you can provide me a solution.

Stephan

I Have One GridViewTextBox Column in a grid and One ComboBox Column based on selection in a combobox column I need cells of TextBox Column to contain either string or integer value how I can do this please help me.

already used below mentioned code but having issue with that I cannot able to put values more than 100 in that and getting up/down arrows to increases and decrease values but I dont need them.

 radGridView1.EditorRequired += new Telerik.WinControls.UI.EditorRequiredEventHandler(radGridView1_EditorRequired);  // binding event on grid

void radGridView1_EditorRequired(object sender, Telerik.WinControls.UI.EditorRequiredEventArgs e)
        {
            if (this.radGridView1.Columns[1].IsCurrent)
            {
                var a = TextCodes.SingleOrDefault(t => t.Name.Equals(this.radGridView1.CurrentRow.Cells[0].Value));
                if (a == null)
                    return;
                if (a.TextCodeType == TextCodeTypeEnum._datetime)
                {
                    e.Editor = new RadDateTimeEditor();
                    e.EditorType = typeof(RadDateTimeEditor);
                }
                else if (a.TextCodeType == TextCodeTypeEnum._string && a.TextCodeValueList == null)
                {
                    e.Editor = new RadTextBoxEditor();
                    e.EditorType = typeof(RadTextBoxEditor);
                }
                else if (a.TextCodeType == TextCodeTypeEnum._string && a.TextCodeValueList != null)
                {
                    e.Editor = new RadDropDownListEditor();
                    try
                    {
                        ((RadDropDownListEditor)e.Editor).DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;
                    }
                    catch (System.Exception)
                    {
                    }
                    e.EditorType = typeof(RadDropDownListEditor);
                }
                else if (a.TextCodeType == TextCodeTypeEnum._number)
                {
                    e.Editor = new GridSpinEditor();
                    e.EditorType = typeof(GridSpinEditor);
                }
            }
        }

Hello,

I'm having trouble installing Telerik UI for Winforms (version 2023.1.314) on Visual Studio 2022 (version 17.0.5).

When I install the extension I get the error in the attached screenshot. I'm able to make the error go away temporarily by deleting the contents of %localappdata%\Microsoft\VisualStudio\17.0_001382ae\ComponentModelCache. But I still get errors when I try to build the solution that already contains Telerik components indicating that I am missing an assembly reference.

Also, many components in the toolbox don't actually get added to the form when I try to drag and drop them in. 

I've tired uninstalling and reinstalling Telerik several times and running the repair function on the Telerik installer.  When available I've tried running the Toolbox Configurator and the Upgrade Wizard but neither have made any difference. Most often the Telerik menu doesn't populate with either  (see menu screenshot attached). 

Dim imageStream As Stream = File.OpenRead(DestPath)
                    Dim radDocument As RadDocument = txtBody.Document

 Dim caretPosition As DocumentPosition = radDocument.CaretPosition

caretPosition.MoveToLastPositionInDocument()

Dim inlineImage As New ImageInline(imageStream)
                    txtBody.InsertInline(inlineImage)

this way the picture shows up in radrichtextbox but after sending the mail it only shows up in my attachments. I also want it to come embedded in the body, that is, in the part where the message is written. What should I do?

I have a RadTextBox whose MouseDown and MouseMove events do not fire when the mouse is inside the text box.

Running Spyxx reveals that at least the MouseMove event is firing. But both events are being ignored by the RadTextBox control.

Bug? Is this a known issue?

Hi,

Is it possible to export to Excel only the selected rows from a gridview using GridViewSpreadExport?

My code looks like this at the moment:

Using ms As New System.IO.MemoryStream

            mspreadExporter = New GridViewSpreadExport(radDocuments) 'radDocuments is the gridview

            Dim exportRenderer As New SpreadExportRenderer()

            mspreadExporter.ExportFormat = SpreadExportFormat.Xlsx
            mspreadExporter.ExportVisualSettings = False
            mspreadExporter.HiddenColumnOption = HiddenOption.DoNotExport
            mspreadExporter.ChildViewExportMode = ChildViewExportMode.ExportCurrentlyActiveView
            mspreadExporter.SheetMaxRows = ExcelMaxRows._1048576
            mspreadExporter.SheetName = "Report"
            mspreadExporter.FileExportMode = FileExportMode.CreateOrOverrideFile
            mspreadExporter.RunExport(ms, exportRenderer)

            Using fileStream As New System.IO.FileStream(strFilename, IO.FileMode.Create, IO.FileAccess.Write)
                ms.WriteTo(fileStream)
            End Using

End Using

Hi, good morning.

I am using a Pivotgrid, PivotFieldList and Chartview.

The chartview graphs whatever the Pivotgrid has, but there are times when the Pivotgrid has too many records and the Chartview takes a long time to generate.

As seen in the documentation, a Chartview takes time, because it is recalculating the points to regenerate the graph, after having created it previously.

This has led me to think that if instead of the Chartview graphing the Pivotgrid, it would better graph a DataTable.

My idea is the following:
I already generated a filtered DataTable, the result of the interaction between the Pivotgrid and the PivotFieldList and that DataTable fills the Chartview to generate the graph, I think it would take less time to create the graph, since each time the filtered DataTable would be created.

I was looking at this example that you provide to create a graph from a datatable:
https://www.telerik.com/forums/use-radgridview-as-a-datasource-for-radchartview

But it does not graph as expected, that is, it does not show the graphs the same as when the pivotgrid is filled.

Is it possible to do this, or even if you do, will the graph creation time be the same? Because if so, there is no point in working on this solution.

Thank you very much for your attention.
