How to enable header cell borders if its celltype is set to TextBox in WinForm GridControl?
1 min read
By default, if the header cell type is set to TextBox, the cell borders of those cells will disappear. To draw the borders for the header cells, use the e.Style.Borders property of the QueryCellInfo event.
//Event Triggering.
this.gridControl1.QueryCellInfo += gridControl1_QueryCellInfo;
//Event Handling.
void gridControl1_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)
{
if (e.ColIndex == 0)
{
e.Style.CellType = GridCellTypeName.TextBox;
e.Style.Borders.Bottom = e.Style.Borders.Right = new GridBorder(GridBorderStyle.Solid, Color.FromArgb(100, 100, 100), GridBorderWeight.Thin);
e.Style.Borders.Top = e.Style.Borders.Left = new GridBorder(GridBorderStyle.Solid, Color.White, GridBorderWeight.Thin);
}
}'Event Triggering.
AddHandler Me.gridControl1.QueryCellInfo, AddressOf gridControl1_QueryCellInfo
'Event Handling.
Private Sub gridControl1_QueryCellInfo(ByVal sender As Object, ByVal e As GridQueryCellInfoEventArgs)
If e.ColIndex = 0 Then
e.Style.CellType = GridCellTypeName.TextBox
e.Style.Borders.Right = New GridBorder(GridBorderStyle.Solid, Color.FromArgb(100, 100, 100), GridBorderWeight.Thin)
e.Style.Borders.Bottom = e.Style.Borders.Right
e.Style.Borders.Left = New GridBorder(GridBorderStyle.Solid, Color.White, GridBorderWeight.Thin)
e.Style.Borders.Top = e.Style.Borders.Left
End If
End SubThe screenshots below illustrate the borders for the GridCells.
