RadMemnuItems have a .showArrow propery, which shows a little triangle to the right of the item, to indiate there are sub-items.

Does anyone know how to make the arrow appear at the bottom of the item? There 's Direction property, but that changes where the wrrow points, which is useful, but does not change its position.

Is it possible to send mail report from RadGridView Telerik WinForms C#. I have button to print when the button is clicked the report should export to pdf also.

Hi,

I'd like to customize the location of a MessageBox. Ideally, I would just set a parent control and the MessageBox would center itself to the parent.

I tried this ((0,0) to make it obvious) but it doesn't work:  

  'Dim pt As Point = New Point(Me.Parent.Location.X + Me.Location.X, Me.Parent.Location.Y + Me.Location.Y)
  'Telerik.WinControls.RadMessageBox.Instance.Location = New Point((pt.X + Me.Width / 2) - (Telerik.WinControls.RadMessageBox.Instance.Width / 2), (pt.Y + Me.Height / 2))
  Telerik.WinControls.RadMessageBox.Instance.Location = New Point(0, 0)
  Dim ds As DialogResult = Telerik.WinControls.RadMessageBox.Show(Me, "Are you sure?", "Clear form",
                                                                        MessageBoxButtons.YesNo, RadMessageIcon.Question,
                                                                        MessageBoxDefaultButton.Button1)

I've also found this bit of code (modified it according to my needs) from an older answer to someone else's similar question:

Private Sub Instance_LocationChanged(sender As Object, e As EventArgs)
        RemoveHandler RadMessageBox.Instance.LocationChanged, AddressOf Instance_LocationChanged

        Dim box As RadMessageBoxForm = sender
        Dim pt As Point = New Point(Me.Parent.Location.X + Me.Location.X, Me.Parent.Location.Y + Me.Location.Y)
        box.Location = New Point((pt.X + Me.Width / 2) - (box.Width / 2), (pt.Y + Me.Height / 2))

        AddHandler RadMessageBox.Instance.LocationChanged, AddressOf Instance_LocationChanged
    End Sub

But the problem here is that the MessageBox is then static and can't be moved.

Suggestions?

Using version 2021.1.326.40.

Hello,

I am using the RadSpreadProcessing library to create Excel reports: https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/overview

I'm using the DataValidation (i.e. ListDataValidationRule) to create dropdowns with a set of values: https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/data-validation

Here's the issue I'm seeing:

I go to try to create a dropdown with the ListDataValidationRule object, but when my string length is >255 characters for the Argument1 property and I export out the report, I receive an error when trying to launch the exported file:

Sample code:

CellIndex dataValidationRuleCellIndex = new CellIndex(0, 0); 
 
ListDataValidationRuleContext context = new ListDataValidationRuleContext(worksheet, dataValidationRuleCellIndex); 
context.ErrorStyle = ErrorStyle.Stop; 
context.ErrorAlertTitle = "Wrong value"; 
context.ErrorAlertContent = "The entered value is not valid"; 
context.InCellDropdown = true; 
context.IgnoreBlank= false;
// Insert string length is > 255 characters
context.Argument1 = <INSERT STRING OF LENGTH > 255 CHARACTERS>; 
 
ListDataValidationRule rule = new ListDataValidationRule(context); 
 
worksheet.Cells[dataValidationRuleCellIndex].SetDataValidationRule(rule); 
 

Hi, How do I go about setting my own image for the help button shown in the title bar at run-time of a RadForm ? I can get the '?' button up but I want to change this form something else.

Thanks Toby
