GetEditorControl Method (ButtonCellType)

In This Topic

Gets the control used to edit the cell (and this implementation always returns null).

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Function GetEditorControl( _
   ByVal id As String, _
   ByVal parent As TableCell, _
   ByVal style As Appearance, _
   ByVal margin As Inset, _
   ByVal value As Object, _
   ByVal upperLevel As Boolean _
) As Control

'Usage
 
Dim instance As ButtonCellType
Dim id As String
Dim parent As TableCell
Dim style As Appearance
Dim margin As Inset
Dim value As Object
Dim upperLevel As Boolean
Dim value As Control
 
value = instance.GetEditorControl(id, parent, style, margin, value, upperLevel)

public override Control GetEditorControl( 
   string id,
   TableCell parent,
   Appearance style,
   Inset margin,
   object value,
   bool upperLevel
)

Parameters

id: Unique identifier of the control
parent: Parent cell (TableCell object) of the control
style: Style settings (Appearance object) for the control
margin: Margin settings (Inset object) for the control
value: Value (as object) to put in the control
upperLevel: Whether the control can render in an up-level browser

Return Value

Control object containing the editor control to edit the cell

Remarks

The Spread component always positions the editor control returned by the GetEditorControl method so that the editor control covers the entire cell.

Example

This example subclasses the ButtonCellType and creates a button cell in the first cell of the spreadsheet.

C#
Visual Basic
