How to add the Button and Text in GridTextColumn in WinForms DataGrid (SfDataGrid)?
By default, you can add either text or button in a GridColumn but, you can add both button and text in a column by customizing GridTextBoxCellRenderer in WinForms DataGrid. In the custom renderer, the OnRender method can be overridden to draw buttons in the cells.
public class GridTextButtonCellRenderer : GridTextBoxCellRenderer
{
public GridTextButtonCellRenderer(SfDataGrid dataGrid)
{
IsEditable = true;
DataGrid = dataGrid;
}
protected override void OnRender(Graphics paint, Rectangle cellRect, string cellValue, CellStyleInfo style, DataColumnBase column, RowColumnIndex rowColumnIndex)
{
base.OnRender(paint, cellRect, cellValue, style, column, rowColumnIndex);
//To set the rectangle for button in the cell.
var rect = new Rectangle(cellRect.Location.X + cellRect.Width - 22, cellRect.Location.Y, 20, cellRect.Height);
(column.GridColumn as GridTextButtonColumn).CellButton = new CellButton();
(column.GridColumn as GridTextButtonColumn).CellButton.Image = Image.FromFile(@"..\..\Images\icons.png");
(column.GridColumn as GridTextButtonColumn).CellButton.TextImageRelation = TextImageRelation.ImageBeforeText;
PropertyInfo highlightedItemProperty = (column.GridColumn as GridTextButtonColumn).CellButton.GetType().GetProperties(BindingFlags.NonPublic | BindingFlags.Instance).Single(pi => pi.Name == "Bounds");
highlightedItemProperty.SetValue((column.GridColumn as GridTextButtonColumn).CellButton, rect);
//To draw the button in cell
DrawButton(paint, cellRect, rect, "...", new ButtonCellStyleInfo(), column, rowColumnIndex);
}
}//To add custom renderer into SfDataGrid.
this.sfDataGrid.CellRenderers.Add("TextButton", new GridTextButtonCellRenderer(this.sfDataGrid));
//To add TextButtonColumn in grid
this.sfDataGrid.Columns.Add(new GridTextButtonColumn() { MappingName = "CustomerID", Width = 140 });
