Hello, John,
In order to customize the cells in the grid within the MultiColumnComboBox, it is suitable to use the CellFormatting event. The following code snippet demonstrates how you can change the color of a selected cell:
public RadForm1()
{
InitializeComponent();
this.radMultiColumnComboBox1.MultiColumnComboBoxElement.EditorControl.SelectionMode = GridViewSelectionMode.CellSelect;
this.radMultiColumnComboBox1.MultiColumnComboBoxElement.EditorControl.CellFormatting += this.EditorControl_CellFormatting;
}
private void EditorControl_CellFormatting(object sender, CellFormattingEventArgs e)
{
if (e.CellElement.IsSelected)
{
e.CellElement.DrawFill = true;
e.CellElement.BackColor = Color.Green;
e.CellElement.NumberOfColors = 1;
}
else
{
e.CellElement.ResetValue(LightVisualElement.NumberOfColorsProperty);
e.CellElement.ResetValue(LightVisualElement.BackColorProperty);
e.CellElement.ResetValue(LightVisualElement.DrawFillProperty);
}
}
Similarly, you can change the color when the mouse hovers over cells. You can track which is the current hovered cell, for example in the MouseMove event, and apply the desired styling to this cell the CellFormatting event. Note, it is important to always reset the applied styles since the cells are reused.
I hope this helps. Should you have any other questions do not hesitate to contact me.

Nadya
