I have this code behind on pageload :

       Dim dss As New DataSet
     
        dss = myProfile.getsubjects(categoryid)

        datagrid1.DataSource = dss.Tables(0)

my dss has 5 columns but i want to show only 2 of them on datagrid. I don't  want to cut the 3 of them as i use all column info.
Just want to show only the 2 columns.

How i change the column name to be diferent from the name of the sql tables i have on my database?

Thanx

Q1. How do I hide a column in a DataGrid or DataTable?

Ans. DataGrid.Columns(index).Visible = False

See also: Mapping type?

Set DataColumn.MappingType as MappingType.Hidden

ONE MORE VERSION: GRID ONLY:

The grid part of a DataGrid is represented by a table. The TableStyles property provides to this table. TableStyles property returns an object of type DataGridTableStyle, which provides access to all columns in the form of DataGridColumnStyles collection. The GridColumnStyles property of DataGridTableStyle returns it, from where you can get one DataGridColumnStyle. The DataGridColumnStyle represents the style of a column and you need to set Width property of DataGridColumnStyle to 0.

Something like this:

For Each dgt As DataGridTableStyle In myDataGrid.TableStyles
Console.WriteLine(dgt.MappingName)
For Each dgc As DataGridColumnStyle In dgt.GridColumnStyles
dgc.Width = 0
Next dgc
Next dgt

Hide a column in the .NET Winforms Datagrid
There are several ways to do this. You can create a custom DataGridTableStyle and add GridColumnStyles for each column in the grid except the column(s) to hide (see my How do I format columns in a datagrid page).

You can create a GridColumnStyle for the column to hide and set its Width to zero (see my Format columns in a datagrid page).

You can also use your DataSet's ColumnMapping property to hide a column.

Can you please help me on the environment i am working at?
