FormatString in HtmlViewDefinition

[Hossein]

Hi

I have used the following code to create a radgridview with Multi-Row's header (Winform Applications).
Everything is ok, but, the FormatString does not work!

Could you allow me tho know, how I could set FormatString in HtmlViewDefinition, Please?

Thanks
Hossein

this.htmlView = new HtmlViewDefinition();
this.htmlView.RowTemplate.Rows.Add(new RowDefinition());

this.htmlView.RowTemplate.Rows[0].Cells.Add(new CellDefinition("Avarez"));
this.htmlView.RowTemplate.Rows[0].Cells.Add(new CellDefinition("Maliyat"));

 GridViewDataColumn Maliyat = (GridViewDataColumn)this.radGridView1.Columns["Maliyat"];
Maliyat.FormatString = "{0:#,###}";

 this.radGridView1.ViewDefinition = htmlView;
