Workaround: Handle the MouseWheel event of the control

private void RadSpreadsheet1_MouseWheel(object sender, MouseEventArgs e)
{
    int offset = this.radSpreadsheet1.SpreadsheetElement.VerticalScrollBar.SmallChange * 3;
    int x = e.Delta < 0 ? offset : -offset;
    this.radSpreadsheet1.SpreadsheetElement.VerticalScrollBar.ClampValue = true;
    this.radSpreadsheet1.SpreadsheetElement.VerticalScrollBar.Value += x;

    RadWorksheetEditor editor = this.radSpreadsheet1.SpreadsheetElement.ActiveSheetEditor as RadWorksheetEditor;
    if (editor != null)
    {
        IRadWorksheetEditorPresenter presenter = (IRadWorksheetEditorPresenter)editor.GetType().GetField("activePresenter", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(editor);
        presenter.SetVerticalOffset(presenter.VerticalOffset + x);
        editor.InvalidateMeasure(true);
    }
}

Using this font is OK:

Font("Calibri", 24, FontStyle.Regular, GraphicsUnit.Pixel)

But using this font is not OK, the Unit is not respected:

Font("Calibri", 24, FontStyle.Italic | FontStyle.Bold, GraphicsUnit.Pixel)

The control also is increased in height.

I have a form with two TextBox controls with ShowEmbeddedLabel and RepositionEmbeddedLabel enabled. The TextBox font size is 18P and the Embedded Label sizes are 18P and 10P. 

When running, the first textbox with the larger EL looks and works fine.  The textbox with the 10P EL, not so much.  The EL rests in the center of the control, rather than the bottom.  What property have I overlooked to have the 10P EL  align to the bottom of the control rather than hover in the center?

I've tried disabling TextBoxElement.AutoSize and setting its Size, but that really confuses the renderer. Messing the the LightVisualElements, didn't help either. Resizing the control almost works, but the descenders, the 'tails', of letters are clipped then the EL is bottom aligned.



Thanks!

1.Make the sheet protected

2. Paste using Ctrl+V

The first message shows:

Then:

Right-click an empty cell and select Copy.

RadMenuComboItem is vanishing before can be reached if its not in main manu colum.

1: works

2: works NOT - menu is popping in but if you move the mouse from "style" to the combobox its vanishing before you can do anything.

Hi Guys,

             the colour scheme on your SchedulerBinderDataSource Appointment Mapping form is barely visible

Could you please darken the text so I can map things without squinting.

Thanks.

Hello support,

i use the radBrowseEditor.

Here the code:

        private readonly string ActualPath_LiteDB = "";

        public F_ApplicationsSettings()
        {
            InitializeComponent();

            //set up actual paths
            ActualPath_LiteDB = Settings.PathToLogLiteDB;
            radBrowseEditor_db_path.Value = ActualPath_LiteDB;

            this.Text = F_Translations.GetTranslationText("settings");
        }

When i set the DialogType to FolderBrowseDialog the initial directory the its working:

But if i set it the DialogType to RadOpenFolderDialog its not working. Its always showing the Desktop folder:

1. Filter the column "code" to show only "(Blanks)"
2. Hit the "Save Layout" button to save the layout into a string
3. Hit the "Load Layout" button. The row is gone
   

This doesn't work in both .NET Framework and .NET 5.

Add a RadForm and set its AutoScroll property to true at design time. When you add any controls that are located outside the form's size a scroll bar appears. However, it seems to be disabled and the user is not allowed to scroll at design time. 

Hello,

So here's what happens. I create a workbook and a worksheet in that wb which I assign as the workbook of a RadSpreadSheet by RadSpreadSheet..Workbook = wb

The first time I assign a name to the first (and only sheet) created in the creation of the wb, the name does appear on that sheet.

Then some code takes this workbook ByVal, creates a new Sheet, makes that sheet the wb's ActiveWorksheet and then changes the ws's name.

You can see in the debugging that the worksheet does have the new name i put there ("2018-05"), but visually this 2nd worksheet has the default name "sheet 2".

Then that wb which is returned by the function is assigned as the RadSpreadSheet's workbook

If I run the code again, so a 3rd sheet is created, then the 3rd sheet will visually have the default name "sheet 3", however in the debugger it says "2018-06" as its name; but most importantly, now sheet 2 has magically changed to what I was seeing its name to be in the debugger ("2018-05").

I'm assuming that If I'm changing the sheet names at runtime, I need to call some method on the Workbook element or something like that in order to update the names. I just couldn't find which method to call.

Best regards,

Ioannis Mamalikidis.
