I want to set the AutoCompleteMode property in ApplyCellStyleToEditingControl subroutine
- by Ranjan Gupta
Hi,
I am creating a DataGridView Column. and it is working well. now I want to customise this column with AutoCompleteMode, and AutoCompleteSource properties to show the customised data. I made the properties for this columns, and these are also working well. but these properties are not working in the "ApplyCellStyleToEditingControl" subroutine.
Please help me to use these column properties in the "ApplyCellStyleToEditingControl" subroutine.
Public Class DataGridViewDataValueColumn

Dim m_AutoCompleteMode As AutoCompleteMode, _
m_AutoCompleteSource As AutoCompleteSource, _
m_AutoCompleteStringCollection As AutoCompleteStringCollection

MyBase.New(New DataValueCell())
End Sub
Public Overrides Property CellTemplate() As DataGridViewCell
Get
Return MyBase.CellTemplate
End Get
Set(ByVal value As DataGridViewCell)
' Ensure that the cell used for the template is a DataValueCell.
If (value IsNot Nothing) AndAlso _
Not value.GetType().IsAssignableFrom(GetType(DataValueCell)) _
Then
Throw New InvalidCastException("Must be a DataValueCell")
End If
MyBase.CellTemplate = value
End Set
End Property
