Use 'SortExpression' to those columns only which you want to sort .

See for example in which column 'Melder' doesnot have SortExpression so you can't sort this column but other can sort :

ASP.NET

<asp:GridView ID="gvOutlookMeldingen" runat="server" 
    AllowSorting="True" 
    OnSorting="gvOutlookMeldingen_Sorting"
    AutoGenerateColumns="False" 
    AutoGenerateSelectButton="True" 
    onselectedindexchanged="GridView_SelectedIndexChanged">
    <Columns>
        <asp:BoundField DataField="Melder" HeaderText="Melder"  />
        <asp:BoundField DataField="Onderwerp" HeaderText="Onderwerp" SortExpression="Onderwerp" />
            <asp:TemplateField HeaderText="Omschrijving" SortExpression="Omschrijving">
                <ItemTemplate>
                    <div style="overflow:auto; width: 500px; height: 200px;">
                        <asp:Label ID="lblOmschrijving" runat="server" Text='<%# Bind("Omschrijving")%>'></asp:Label>
                    </div>
                </ItemTemplate>
            </asp:TemplateField>
        <asp:BoundField DataField="Meldingsdatum" HeaderText="Meldingsdatum" SortExpression="Meldingsdatum" />
        <asp:BoundField DataField="OutlookID" HeaderText="OutlookID" SortExpression="OutlookID" />
    </Columns>
</asp:GridView>

on code behind:

C#

protected void gvOutlookMeldingen_Sorting(object sender, GridViewSortEventArgs e)
{
    switch (e.SortExpression)
    {
        case "Melder":
        if (e.SortDirection == SortDirection.Ascending)
        {
            gvOutlookMeldingen.DataSource = // Asc query for Melder field;
            gvOutlookMeldingen.DataBind();
        }
        else
        {
            gvOutlookMeldingen.DataSource = // Desc query for Melder field ;
            gvOutlookMeldingen.DataBind();
        }
        break;
        // case statements for your other fields.
    }
}
