+# 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](https://www.syncfusion.com/winforms-ui-controls/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](https://help.syncfusion.com/cr/Syncfusion.WinForms.DataGrid.Renderers.GridTextBoxCellRenderer.html). In the custom renderer, the `OnRender` method can be overridden to draw buttons in the cells.
+
+``` csharp
+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);
+    }
+}
+```
+
+``` csharp
+//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 });
+```
