I'am using Developer Express XtraGrid Component to show some data. I have 2 XtraGrid on my Windows Application Form. Both grids have more than 200k+ lines, and 8 columns of data, and I have export to excel button. There are two ways (as I know) for exporting grid data to excel. 1- grid.ExportToXls(); or grid.ExportToXlsx(); 2- Using Office Interop, and OpenXML Utilities If I use grid.ExportToXls(); or grid.ExportToXlsx(); , the process time is faster than Office Interop Codes (for arround 2k lines of data).

The DevExpress Grid (XtraGrid) allows grids and their groups to have summary calculations. The available options are Count, Max, Min, Avg, Sum, None and Custom. Has anyone got some sample code that shows how to calculate a weighted average column, based upon the weightings provided as values in another column?

I would like to know how the XtraGrid and the BandedGrid play togehter and are bound to the underlaying data. The documentation has some explanatory tl;dr-text but i am missing a full working example to set it up in code. So it took me about 2 hours to figure it out. Based on this blog entry i would like to post my answer here. If there is a better way to put the pieces together as in my answer below i would love to know about it. First you have to know that you can bind a plain DataTable to the XtraGrid and that the creation of the banded grid is independent. Below you can see a new instance

I've a DevExpress XtraGrid control with three columns and a unbound checkBoxEdit column for users to select when deleting items from the grid. I'm able to add the checkBoxEdit on the xtraGrid. However, i don't have any idea as to how i can get the selected lists' primary key(s) to be deleted. Any idea is highly appreciated. Thanks I believe you can use the following approach: void InitGrid() { gridControl1.DataSource = new List<Person> { new Person(){ ID = 0 }, new Person(){ ID = 1 }, new Person(){ ID = 2 } }; gridView.Columns["ID"].Visible = false; gridView.Columns.Add(new DevExpress.XtraGrid
