Greetings,
I have a RadGirdView and a RadColorBox.
I want to change back/fore colors of each columns of the Radgridview, using the RadColorBox.
I know that I should use Cell-Formatting of the Radgridview, but the problem is that I can not see (update) the changes at runtime. The cell-formatting does its job only once and that is at the time of starting the program.
Anyway to see the changes at runtime ?
Thanks in advance.

Hello, George,
Indeed, the CellFormatting event is the appropriate solution for customizing the grid's cells. According to the provided information, I suppose that you use the value of the RadColorBox to change the color used in the CellFormatting event. However, note that once the RadColorBox.Value is changed you need to force firing the CellFormatting event in the grid. This can be achieved by calling the RadGridView.MasterTemplate.Refresh method.
I have prepared a sample code snippet for your reference which result is illustrated in the attached gif file:
public RadForm1()
{
InitializeComponent();
this.radColorBox1.ValueChanged += radColorBox1_ValueChanged;
}
private void radColorBox1_ValueChanged(object sender, EventArgs e)
{
this.radGridView1.MasterTemplate.Refresh();
}
private void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
if (e.Column.Name == "ProductName")
{
e.CellElement.DrawFill = true;
e.CellElement.GradientStyle = GradientStyles.Solid;
e.CellElement.BackColor = this.radColorBox1.Value;
}
else
{
e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
}
}
Happy Holidays
