How to Add the Button and Text in GridTextColumn in WinForms DataGrid?

This repository describes 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 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 });
