Devexpress ASPxGridView New Row Disabled

[BioHazRd]

I have code like this with devexpress ASPxGridView. Everything goes well, but when I try to add new row, new row's textbox is disabled...I have KeyFieldName set.\[code\] void BindGrid() { var AnnObj = SearchBarBanners.Select(i => new { Caption = i.Attribute("caption").Value, ID = i.Attribute("id").Value, // this is generated by Guid }).ToList(); ImagesGrid.DataSource = AnnObj; ImagesGrid.DataBind(); }\[/code\]
