The grid does not provide such a control, so you will need to wrap your own control (or a third party one) through the CellEditorManager class.  Here is more information from the help documentation on how to do this :

http://doc.xceedsoft.com/products/XceedGrid/CellEditorManagers.html 

Look at the “Wrapping a control in a CellEditorManager” section.

In an Xceed grid it is possible to use an own control for editting a value in a xceed grid cell.
http://doc.xceedsoft.com/products/XceedGrid/CellEditorManagers.html

I want to use an Color picker to select a color.
When i use the control Janus.Windows.EditControls.UIColorButton i get an red cross in the grid, see also the screenshot (UIColorButton.jpg)

I have the same problem when use an DevComponents.DotNetBar.ColorPickerButton control (see screenshot ColorPickerButton.jpg)

For setting the color i use something like this, but this wont work because of the red cross.

//DevComponents.DotNetBar.ColorPickerButton cp = datarow.Cells[profileColumn].CellViewerManager.Control as DevComponents.DotNetBar.ColorPickerButton;
//if (cp != null)
//{
//    cp.SelectedColor = (Color)value;
//}

 

code for Janus.Windows.EditControls.UIColorButton pCell => Xceed.Grid.Cell > is the cell in the xceed grid Janus.Windows.EditControls.UIColorButton cb = new Janus.Windows.EditControls.UIColorButton(); pCell.CellEditorManager = new CellEditorManager(cb, “SelectedColor”, true, true); pCell.CellViewerManager = new CellViewerManager(cb, “SelectedColor”); code for DevComponents.DotNetBar.ColorPickerButton DevComponents.DotNetBar.ColorPickerButton cpButton = new DevComponents.DotNetBar.ColorPickerButton(); pCell.CellEditorManager = new CellEditorManager(cpButton, “SelectedColor”, true, true); pCell.CellViewerManager = new CellViewerManager(cpButton, “SelectedColor”);

What is the DataType of the color column?  If it is object or Color, it should work fine.

First i read a dataset, with retrieveStructure() everything is in string

Then for each row i change the type to the correct one, bool, color, string, int, ….

They are different types.

The DataType cannot be changed at the cell level, so when using different CellEditorManager in the same column, the Column DataType must be compatible to the value needed by the editor.

In your case, you could use an object DataType for that column, and all editors should work fine.  The other alternative is to handle the SettingControlValue and GettingControlValue on CellEditorManager and SettingControlValue on CellViewerManager to convert the value of the editor to a value supported by the cell, and vise versa (e.g. Color.Red.ToString() in case of a string column).

You can also derive from CellEditorManager and override the SetControlValueCore() and GetControlValueCore() methods to obtain the same result.
