Hi Thanh,
Thank you for writing back.
Here is how to remove the formatting of the current and the selected row and cell and set the colors back to the one from the
ControlDefault theme:
void EditorControl_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
if (e.Row.IsSelected || e.Row.IsCurrent)
{
e.CellElement.GradientStyle = GradientStyles.Solid;
e.CellElement.BackColor = Color.White;
e.CellElement.BorderColor = Color.FromArgb(209, 225, 245);
e.CellElement.BorderWidth = 1;
e.CellElement.BorderBottomColor = Color.FromArgb(209, 225, 245);
e.CellElement.BorderBoxStyle = BorderBoxStyle.SingleBorder;
e.CellElement.BorderGradientStyle = GradientStyles.Solid;
}
else
{
e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.BorderColorProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.BorderWidthProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.BorderBottomColorProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.BorderBoxStyleProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.BorderGradientStyleProperty, ValueResetFlags.Local);
}
}
void EditorControl_RowFormatting(object sender, RowFormattingEventArgs e)
{
if (e.RowElement.IsSelected || e.RowElement.IsCurrent)
{
e.RowElement.GradientStyle = GradientStyles.Solid;
e.RowElement.BackColor = Color.White;
}
else
{
e.RowElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
e.RowElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
}
}
