FIX. RadGridView - cell's back color is not reset when you hover a cell and move the cursor to another cell
To reproduce: please refer to the attached gif file and sample project.

Workaround: when you set the DrawFill property to true, specify the BackColor to the desired one and reset for the rest of the cells.

private void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    if (e.Column.Name == "ProductName" && e.Row is GridViewDataRowInfo)
    {
        if (e.CellElement.Value.ToString().Contains("C"))
        {
            e.CellElement.DrawFill = true;
            e.CellElement.BackColor = Color.Yellow;
            e.CellElement.GradientStyle = GradientStyles.Solid;
            e.CellElement.ForeColor = Color.OliveDrab;
        }
        else
        { 
            e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
            e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
            e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);  
            e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);  
        }
    }
    else
    { 
        e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);    
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);  
    }
}

Each theme has its own specific theming mechanism for RadGridView. For example, the ControlDefault theme is designed to paint the fill of Current and Selected states in the row element (the fill of cells is not painted DrawFill = false). Hover state is painted in the cells and if we decide to set DrawFill of the cell to true in its normal state on CellFormatting, the BackColor will remain from its previous state (yellow for Hover). The theme is designed not to paint the fill on normal state and this is why the BackColor property is not set for this state.
Currently, we can suggest setting manually the BackColor of cells.
