Hi Team,

We are planning to migrate Telerik.WinControls.RichTextEditor.dll (2023.1.314.40) in visual studio 2022.

We are unable to compile the program and getting an errors like below.

• The type or namespace name 'RadDocument' could not be found (are you missing a using directive or an assembly reference?)
• The type or namespace name 'StyleDefinition' could not be found (are you missing a using directive or an assembly reference?)
• The type or namespace name 'BaselineAlignment' could not be found (are you missing a using directive or an assembly reference?)
• The type or namespace name 'UnderlineType' could not be found (are you missing a using directive or an assembly reference?)

• 'RadRichTextEditor' does not contain a definition for 'DocumentView' and no accessible extension method 'DocumentView' accepting a first argument of type 'RadRichTextEditor' could be found (are you missing a using directive or an assembly reference?)

What is an equivalent namespaces for following references? Could you please help on this below?

• using Telerik.WinControls.RichTextBox;
• using Telerik.WinControls.RichTextBox.FileFormats.Rtf;
• using Telerik.WinControls.RichTextBox.Layout;
• using Telerik.WinControls.RichTextBox.Lists;
• using Telerik.WinControls.RichTextBox.Model;
• using Telerik.WinControls.RichTextBox.Model.Styles;
• using Telerik.WinControls.RichTextBox.UI;
• using Telerik.WinControls.RichTextBox.FormatProviders;
• using Telerik.WinControls.RichTextBox.FormatProviders.Txt;

Note: Its working fine in the Telerik.WinControls.RichTextBox.dll (2013.3.1127.40)

example program:

private void InitializeCurrentFontStyles(StyleDefinition styleDefinition) { try { UnderlineType underlineType = (UnderlineType)styleDefinition.GetPropertyValue(Span.UnderlineTypeProperty); this.radBtnUnderlineStyle.ToggleState = underlineType != UnderlineType.None ? ToggleState.On : ToggleState.Off; string fontFamiliy = (string)styleDefinition.GetPropertyValue(Span.FontFamilyProperty); this.radDropDownListFont1.SuspendSelectionEvents = true; this.radDropDownListFont1.Text = fontFamiliy; this.radDropDownListFont1.SelectedValue = fontFamiliy; this.radDropDownListFont1.SuspendSelectionEvents = false; float fontSize = (float)styleDefinition.GetPropertyValue(Span.FontSizeProperty); fontSize = (float)Math.Round(Unit.DipToPoint(fontSize), 1); this.EnsureFontSize(fontSize.ToString()); TextStyle fontStyle = (TextStyle)styleDefinition.GetPropertyValue(Span.FontStyleProperty); this.radBtnBoldStyle.ToggleState = fontStyle.HasFlag(TextStyle.Bold) ? ToggleState.On : ToggleState.Off; this.radBtnItalicStyle.ToggleState = fontStyle.HasFlag(TextStyle.Italic) ? ToggleState.On : ToggleState.Off; } catch (Exception ex) { RadMessageBox.SetThemeName("Office2007Silver"); RadMessageBox.Show(ex.Message, res_man.GetString("ProposalEntityMaster", PNxt_BL.Common.CultureInfo), MessageBoxButtons.OK, RadMessageIcon.Error); } using (InsertTableForm insertForm = new InsertTableForm()) { insertForm.Owner = this; insertForm.ThemeName = "Office2007Silver"; if (insertForm.ShowDialog() == System.Windows.Forms.DialogResult.OK) { this.radRichTextBox1.InsertTable(insertForm.RowsCount, insertForm.ColumnsCount); } } this.radRichTextBox1.DocumentView.Caret.Hide(); }

Hello,

is it possible to somehow activate a funktion to drag and hold an appointment to the latest possible date and the scheduler will after a few seconds of holding the appointment in this position automatically change the displayed calender to for example the next week so that you can drop the appointment here?

Hi,

I'm having a problem while exporting a GridView containing some GridViewCommandColumns to a XLS.

I get a FormatException error in Telerik.WinControls.GridView.dll on these columns.

The code I use for export:

GridViewSpreadExport spreadExporter = new GridViewSpreadExport(gridView);
spreadExporter.ExportChildRowsGrouped = true;
spreadExporter.HiddenColumnOption = Telerik.WinControls.UI.Export.HiddenOption.DoNotExport;
spreadExporter.HiddenRowOption = Telerik.WinControls.UI.Export.HiddenOption.DoNotExport;
SpreadExportRenderer exportRenderer = new SpreadExportRenderer();
spreadExporter.RunExport(sDialog.FileName, exportRenderer);

I don't necessarily need these columns in a XLS, so I tried to hide them before exporting, set some export properties and even set values:

gridView.Columns["column1"].IsVisible = false;
gridView.Columns["column1"].ExcelExportType = Telerik.WinControls.UI.Export.DisplayFormatType.None;

foreach (var row in gridView.Rows)
{
    row.Cells["column1"].Value = 1;
}

The only way a grid exports correctly is when GridViewCommandColumns are deleted from the grid.

Any idea what should I try? I use version 2021.2.511.40.

Thanks in advance.

I'm trying to make a clear distinction between the parent and child rows.  I tried the following to change the background color of the child rows:

CellFormatting += (sender, args) =>
{
    if (args.Row.HierarchyLevel > 0)
        args.CellElement.BackColor = Color.Aquamarine;
};

It works, but only when my mouse hovers over a child row.

Also, I'm wondering why the rows in the child grid have plus signs to their left (see the attached image) when there is no third level.

I have not found it easy to figure this out from the API documentation.  There are probably properties that could get me what I want, but are they in the row class?  The template?  The child template?  The grid?  The view?  <shrug>

I once came across a document on your site that describes the overall grid structure and the relationships between these components.  Whether or not I can get help on these specific issues I'd appreciate a link to that document.

Thanks.

Never did this before, but I need to make a custom change to a control that will affect all instances of it throughout the application. If the user clicks in a masked edit control at any position and the control is empty, the cursor should jump to position 1. It works fine when I use the event handler of the control directly like this:

 private void mtbHomePhone_Click(object sender, EventArgs e)
        {
            if (mtbHomePhone.Value?.ToString()?.Length == 0)
            {
                mtbHomePhone.SelectionStart = 1;
                mtbHomePhone.SelectionLength = 0;
            }
        }

I'm trying to inherit from the control like this (using MyMaskedEdit in the designer.cs in place of RadMaskedEditBox) but the event is not firing. What am I doing wrong?

using Telerik.WinControls.UI;

namespace VisionUI.Common
{
    public class MyMaskedEdit : RadMaskedEditBox
    {
        protected override void OnClick(EventArgs e)
        {
            base.OnClick(e);

            if (this.Value?.ToString()?.Length == 0)
            {
                this.SelectionStart = 1;
                this.SelectionLength = 0;
            }
        }
    }
}

Thanks

Hi Team,

We are using RadDropDownList control version (2023.1.314)

We are getting  'System.StackOverflowException' exception while assigning value in the dropdownlist (its keep on recursion).

Could you please help on this?. Please find sample program below.

We are using visual Studio 2022 and Telerik.WinControls.UI.dll(2023.1.314)

Note: Its working fine in 2013.3.1.1127 version.

 private void comboBox1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
 {
    setOldValue();
 }

 private void setOldValue()
 {
    comboBox1.SelectedValue = 2;
 }

 private void button1_Click(object sender, EventArgs e)
 {
    comboBox1.SelectedValue = 1;
 }

Thanks

For some reason - probably due to  me doing some re-sizing of columns - my sheets are now opening scrolled a bit to the right, which means my important left-hand columns are not visible without scrolling.

I assume this will be annoying to users - It certainly took me an hour to figure out what had happened to my left-hand columns. :-(

I tried to make the sheet scroll left in the control.load event:

 mySpreadsheetControl.HorizontalScroll.Value = 0

...but that didn't seem to work.

Does anyone know the right way to scroll left in a sheet?

Thanks

Hello,

i am using custom status and i would like to know if it is possible to set the width of the displayed status field.
I haven't found the right element at the AppointmentFormatting event to access the status field.
