Logical / Technical Problem with ASP gridview and objectdatasooruce

Hi Experts

Here is my problem: I have two buttons Dispatch / Update. When I click on Update button I need to update the code for Provider. When I click on Dispatch button it doesnt update the code for Provider.

Is there any way that in ODS when I click on dispatch call the update function and then the dispatch function.

the ODS only support one Update Method. Is possible to have more that one with different names.

Any help will be appreciated

I have this code with the buttons

 <asp:Button ID="btnUpdate" Text="Update" runat="server" CommandArgument="Update"
            CommandName="Update" />
        <asp:Button ID="btnDispatch" Text="Dispatch" runat="server" CommandArgument="Dispatch"
            CommandName="Dispatch" />

Select allOpen in new window

Then I have this ODS:

<asp:ObjectDataSource ID="odsDetail" runat="server" TypeName="DataAccess.WorkOrder"
    SelectMethod="getWODetails" UpdateMethod="updateWODetails">
    <SelectParameters>
        <asp:QueryStringParameter Name="WONum" Type="String" QueryStringField="WONum" />
        <asp:QueryStringParameter Name="SiteID" Type="String" QueryStringField="SiteID" />
        <asp:QueryStringParameter Name="OrgID" Type="String" QueryStringField="OrgID" />
    </SelectParameters>
    <UpdateParameters>
        <asp:QueryStringParameter QueryStringField="WoNum" Name="WoNum" Type="String" />
        <asp:QueryStringParameter Name="SiteId" Type="String" QueryStringField="SiteID" />
        <asp:Parameter Name="description" Type="String" />
        <asp:Parameter Name="WLoc" Type="String" />
        <asp:Parameter Name="AssetNum" Type="String" />
        <asp:Parameter Name="woPriority" Type="String" />
        <asp:Parameter Name="worktype" Type="String" />
        <asp:Parameter Name="details" Type="String" />
        <asp:Parameter Name="Location" Type="String" />
        <asp:Parameter Name="Asset" Type="String" />
        <asp:Parameter Name="Priority" Type="String" />
        <asp:Parameter Name="reportedby" Type="String" />
        <asp:Parameter Name="ProjNum" Type="String" />
        <asp:Parameter Name="reportdate" Type="String" />
        <asp:Parameter Name="provider" Type="String" />
    </UpdateParameters>
</asp:ObjectDataSource>

Select allOpen in new window

Finally the code that Updates the DB

case "Update":
                    string updmsg = string.Format("Work Order {0} has been updated successfully", Request.QueryString["WONum"]);
                    imsg.ShowMsg(updmsg, false); 
                    break;
                
                case "Dispatch":
                    
                    (new DataAccess.WorkOrder()).updateWOStatus(Request.QueryString["WONum"],"INPRG", Request.QueryString["SiteID"], Request.QueryString["OrgID"], (fvDetail.FindControl("txtreportedby") as RadTextBox).Text);
                    //Page.ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind();", true);
                    string dismsg = string.Format("Work Order {0} has been dispatched successfully", Request.QueryString["WONum"]);
                    imsg.ShowMsg(dismsg, true);
                    break;
