Hi,

How can we sort a datagrid if the grid is set to autogenerate=false? sorting ASC then DSC using mouse lcik on the column header.
The grid is being populated by data from sql server.

Thanks.


    Sub Sort_Grid(sender As Object, e As DataGridSortCommandEventArgs)
            Dim SortExpression As String
            SortExpression = e.SortExpression.ToString()
            If SortMode = "Desc" Then
              SortMode = "Asc"
              SortExpression = SortExpression + " " + "Desc"
            Else
              SortMode = "Desc"
            End If
            Dim odataView as DataView = GenerateSource().DefaultView
             odataView.Sort=SortExpression
             datagrid1.DataSource=odataView
            datagrid1.DataBind()
    End Sub 'Sort_Grid

The above code will work for 2 way sort, just make sure following things:

1) In your Datagird specify SortExpression of each column that you want to Sort:

<asp:BoundColumn DataField="ColumnName" SortExpression="ColumnName" HeaderText="ColumnName"></asp:BoundColumn>

2) Declare SortMode Variable as shared with your class declaration:

Public Shared SortMode As String = "Asc"

3) write above code in Sort Command of DataGrid.
