How to implement a fill paste in the WinForms GridControl?

Platform: WinForms |
Control: GridControl

Fill paste in grid

You can copy the cell value and replicate it by selecting a range. Then paste this value into that range. This is called Fill Paste.

You can try to handle this in the ClipboardPaste event.


void gridControl1_ClipboardPaste(object sender, Syncfusion.Windows.Forms.Grid.GridCutPasteEventArgs e)
    DataObject data = (DataObject)Clipboard.GetDataObject();
    string[] rows = null;
    int numRows = 0;
    int numCols = 0;
    //Get the size of the paste
        string s = (string)data.GetData(DataFormats.Text);
        rows = s.Split(new char[]{'\n'});
        numRows = rows.GetLength(0);
        if(numRows > 0 && rows[numRows - 1].Length == 0)
            numRows--; //remove extra empty row if present
        if(numRows > 0)
            string[] cols = rows[0].Split(new char[]{'\t'});
            numCols = cols.GetLength(0);
    //paste one to many
    if(numRows == 1 && numCols == 1 &&   !this.gridControl1.Selections.Ranges.ActiveRange.IsEmpty)
        e.Handled = true;
        e.Result = true;



Private Sub gridControl1_ClipboardPaste(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.GridCutPasteEventArgs)
    Dim data As DataObject = CType(Clipboard.GetDataObject(), DataObject)
    Dim rows() As String = Nothing
    Dim numRows As Integer = 0
    Dim numCols As Integer = 0
    'Get the size of the paste
    If data.GetDataPresent(DataFormats.Text) Then
        Dim s As String = CStr(data.GetData(DataFormats.Text))
        rows = s.Split(New Char(){ControlChars.Lf})
        numRows = rows.GetLength(0)
        If numRows > 0 AndAlso rows(numRows - 1).Length = 0 Then
            numRows -= 1 'remove extra empty row if present
        End If
        If numRows > 0 Then
            Dim cols() As String = rows(0).Split(New Char(){ControlChars.Tab})
            numCols = cols.GetLength(0)
        End If
    End If
    'paste one to many
    If numRows = 1 AndAlso numCols = 1 AndAlso (Not Me.gridControl1.Selections.Ranges.ActiveRange.IsEmpty) Then
        Me.gridControl1.ChangeCells(Me.gridControl1.Selections.Ranges.ActiveRange,    rows(0))
        e.Handled = True
        e.Result = True
    End If
End Sub

After applying the properties, the Grid is as follows.
