C# Forcing a column to display checkbox

Hello, I was wondering how could I change a column to act like a true / false type to allow me to check / uncheck its rows.

First, the datatype of the column should be <b>System.Boolean</b>.
Second, you should create an <b>Xceed.Grid.Editors.GridCheckBox</b> and use it as cellviewer and celleditor of the column, like this:<code>
Xceed.Grid.Editors.GridCheckBox checkbox = new Xceed.Grid.Editors.GridCheckBox();
Xceed.Grid.Column column = myGrid.Columns[“myBooleanColumn”];
column.CellViewer = checkbox;
column.CellEditor = checkbox;
</code>

If you want to check/uncheck a checkbox with only a single click, you can set the <b>SingleClickEdit</b> property of the gridcontrol to true.

Did not pay attention to this info :).

Anyway, Tommy, when my colums go true / false style, the also become opaque, that is, they do not show my Xceed grids background :(. I hope there is a way to walk around this one…

Since the CellEditor and CellViewer are using the same code to paint, and the checkbox control does not support transparent background, it is why you are having opaque background.

You can have the checkbox to only take the place it need instead of all the cell space. You do that by setting the GridCheckBox.FitToCell property to False. That way the control will only take the space needed, and you will then see the background of the Cell (Grid). Just note that will also change the way the checkbox get checked. The user will now need to click exactly on the checkbox to check or uncheck (If FitToCell is set to False (Default), clicking anywhere on the cell check or uncheck the checkbox).
