2. Add column into Columns collection (Instances of DataColumn).
3. Rows collection to add/remove/update/list rows.

I want to insert,update,delete,select using dataset in vb.net

To bind to a gridview u dont require a dataset instead u can use a datatable for that.
Here i explain u how to do that.

1. Drag drop one grid view into ur form
2. Make it autogenerate colums "false" and showfooter=true
3. Right click on the top of the gridview and select option edit columns
4. Add 4 template columns over there
Name each columns header text as u want like user no, name, desg, dob
5. The gridview code am given below

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" ShowFooter="True" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowCommand="GridView1_RowCommand" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating">
            <Columns>
                <asp:TemplateField HeaderText="UserNo">
                <ItemTemplate>
                    <asp:Label ID="lblNo" runat="server" Text='<%#Eval("No") %>'></asp:Label>
                </ItemTemplate>
                <FooterTemplate>
                    <asp:TextBox ID="txtFNo" runat="server" ></asp:TextBox>

============================================
While saving into the database u can take the gridview data from ViewState["Data"]
like this

DataTable dt=(DataTable)ViewState["Data"];

Hope this will clear ur doubt
