How to disable the context menu for the textbox in edit mode in WinForms DataGrid ?
In WinForms DataGrid (SfDataGrid), ContextMenu can be disabled for a TextBox in edit mode by deriving a new class from GridTextBoxCellRenderer and overriding the OnWireEditUIElement while assigning an empty context menu into the ContextMenu property of TextBox.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
//Remove existing TextBox Renderer
sfDataGrid.CellRenderers.Remove("TextBox");
//Add customized TextBox Renderer
sfDataGrid.CellRenderers.Add("TextBox", new GridTextBoxCellRendererExt());
}
}
public class GridTextBoxCellRendererExt : GridTextBoxCellRenderer
{
protected override void OnWireEditUIElement(TextBox uiElement)
{
base.OnWireEditUIElement(uiElement);
//To prevent the default context menu of a TextBox from showing up, assign a empty context menu as shown below
uiElement.ContextMenu = new ContextMenu();
}
} Note:
This can also be done for GridNumericColumn by deriving a new class from GridNumericCellRenderer.
Take a moment to peruse the WinForms DataGrid - Customize Column Renderer documentation, where you can find about customize column renderer with code examples.
