sorting a datagrid

Hello!

I need help in making my datagrid sortable by clicking a column header.

In the datagrid's property builder, Allow Sorting is checked. I am using a
Bound column and it's Sort Expression is set to the same value as the Data
Field value. But I dont know how to implement:

private void dgResults_SortC ommand(object source,
System.Web.UI.W ebControls.Data GridSortCommand EventArgs e)
{

}

Please help.

Hi,

How you fill the datagrid?, are you using a datatable?

If you're using a datatable you can use this code:

//When you get the data from (for instance :database)

DataView dv = new DataView();
dv=Yourdatatabl e.DefaultView;
Page.Session.Ad d("DataViewOrig inal",dv);//put into the session the view
this.DataGrid1. DataSource=dv;//assign the data source
this.DataGrid1. DataBind();
//In your sortCommand method
if(Page.Session["DataViewOrigin al"]!=null) //if exists the dataview in the
session
{
DataView dv=(DataView) Page.Session["DataViewOrigin al"]; //take the view
dv.Sort=e.SortE xpression;//sort the view by the name of the column header
clicked
this.DataGrid1. DataSource=dv; //assign the source
this.DataBind() ; //show the info
}
Hope this helps.
Regards.

Hi, I'm programatically sorting in a datagrid. When a column header is clicked, the sort happens twice for some reason, making it looks like it only sorts in descending order. I can tell it sorts twice because I inserted a messagebox in the dgMouse (MouseUp) event. Before ok is pressed, the table changes from the order it was loaded to ascending order. After ok is pressed, it goes to descending. The code is below. Any idea why...

Hi, Using VB.NET. I have a datagrid having a strongly typed array of objects as its data source. The data from the array of objects is displayed by means of a table style, which is fine, but I cannot sort the data when I click on the column header. I have set the tablestype.allowsorting = true, but this has no effect.

I thought the only thing I had to do to disable column sorting in VB.NET was to set datagrid.AllowSorting = False. Unfortunately this has never worked for me. I discovered another set of code that seems to work for 99% of the cases where I need to disable datagrid column sorting: Private Sub datagrid_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles datagrid.MouseDown Dim pt As New Point(e.X,...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
