FormView Manual Data Updating

I've posted this some place else but have not heard from anyone and hoping I get better luck here. Note: Sorry about the formating, not sure what happened.I have a FormView that I user for updating a record. There is a link button that when fires should perforom the updating viaBLL and DAL. I am not using built-in ODS and I will not condsider using it. I have all my grids and formviews populated manuualy by calling methods that fetch the data from the database. For instance my details view is populated like this: protected void DlMembers_ItemCommand(object source, DataListCommandEventArgs e) { if (e.CommandName.ToString() == "Select") { DlMembers.Visible = false; lblError.Text = string.Empty; lblError.Visible = false; fvMemberDetail.Visible = true; fvMemberDetail.ChangeMode(FormViewMode.Edit); MemberBLL getMemberInfo = new MemberBLL(); int Ident = Convert.ToInt32(e.CommandArgument.ToString()); fvMemberDetail.DataSource = getMemberInfo.GetMemberByIdent(Ident); fvMemberDetail.DataBind(); } if (e.CommandName.ToString() == "DeleteSelected") { DlMembers.Visible = true; lblError.Text = string.Empty; lblError.Visible = false; fvMemberDetail.Visible = false; fvMemberDetail.ChangeMode

Automatically set a property value for a new record in a Dynamic Data application.

I have a SalesOrderItem table, and it has a UnitPrice column in case the salesperson wishes to override the unit price of the Product for that order item.

In an ASP.NET Dynamic Data application, what would be the best way to set that UnitPrice property on a new SalesOrderItem based on the standard UnitPrice for the product? In other words, when the user clicks New on the 'Items' screen for a sales order, the UnitPrice field should already be filled in with the normal unit price for the product.

This was originally asked by myself on StackOverflow at: http://stackoverflow.com/questions/3538234/automatically-set-a-property-value-for-a-new-record-in-a-dynamic-data-application

Cannot INSERT record using Asp.Net Dynamic Data Domain Service Web Applications

Hi, I am working on a 'Asp.Net Dynamic Data Domain Service Web Application' project using just 2 tables, FAQ_Categories and FAQs. The FAQs table has a foreign key to the FAQ_Categories. The steps are straight forward. Add a new project (Asp.Net Dynamic Data Domain Service Web Applications) Add folders Model ( for Linq2Sql datacontext), Domain (for the Domain Services class) Add Linq2Slql and add the 2 tables to the designer. Build the project. Add the Domain Service Class to the Domain folder. in the wizard select the DataContext, uncheck the Enable Client & Expose ODate checkbox Check bothe table & their corresponding Enable Editing tables checbox Check the Generate Metadata class Click OK. In Global.asax set Scaffold to true and add the DomainService name. Build and run. Pages List and Detail are working fine. But if I try to insert a new record, I get the error "FaqId is required" Faq_ID is the primary key in the database table and it is set to Identiy. The Datacontext is correct, it marked the FAQ table with <Global.System.Data.Linq.Mapping.ColumnAttribute(Storage:="_CustomerId", AutoSync:=AutoSync.OnInsert, DbType:="Int NOT NULL IDENTITY", IsPrimaryKey:=true, IsDbGenerated:=true)> _ I tried this using Linq2Sql, Entity Framework, And both in VB and C# with the same result. I am using VS20

Accessing master formview data from a nested detail formview?

Hi all, I would like to ask if it is possible to access data on a master FormView from a nested detail FormView. I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting.

Display Inserted Record After Insert Using A FormView

Updating an item in one list based on data from another

I thought I understood this fairly well, but it seems that I am missing something. I have created a change management site that uses a calendar list to mark upcoming changes to our IT systems. I have also created a second list to track some information about the change items that I don't want to show up on the calendar, such as what the outcome of the change was or if the change process was properly followed. So I have the calendar list and another list called results. I know that there needs to be a unique identifier that each list item will have in common, so in the results list I created a column called Change Number. When a new change item is created in the Change Management calendar a workflow runs that notifies some people that a new change has been submitted, and the last step in that workflow creates a new list item in the results list and sets the Change Number field to be equal to the current item ID field. That part is working right now. When I create a new change item I can open the results list and see that there is a new item and it has the proper number in the Change Number field. What isn't working is when I try to take actions in other workflows that use data from both lists. An example is notifying the creator of the change that it has been approved. When the list item is changed a workflow starts that

Problem getting same record when trying to populate data into texboxes when selecting a row/record f

I can't seem to get the select record from the datagrid to populate in the textboxes. I get the same record no matter what I select in the datagrid. Hopefully someone can help with this. I tried using a where clause for POPULATION_LIST_ID = '" & Me.lblPopulationID.Text & "' and I get a ORA-01722 error - invalid number. Here is the code I have so far for the grid:

  Protected Sub MHGrid_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles MHGrid.SelectedIndexChanged
        Me.Table1.Visible = True
        Me.MHGrid.Visible = True

        Dim dvSql As DataView = DirectCast(MHFoundation.Select(DataSourceSelectArguments.Empty), DataView)

        Me.MHFoundation.SelectCommand = "SELECT POPULATION_LIST_ID, FIRST_NAME, MIDDLE_NAME, SSN, BIRTH_DATE, ADDRESS, SPOUSE_NAME, OTHER_ID2, WORK_PHONE, PREFERRED_COMMUNICATION, LAST_NAME, NAME_PREFIX, NAME_SUFFIX, MRN1, CITY, STATE, ZIP, CHILDREN,OTHER_ID1,POPULATION_TYPE,HOME_PHONE,CELL_PHONE,POPULATION_RATING,NOTES,EMAIL,PERSON_TYPE FROM CHP_POPULATION_LIST "

Best way to handle constantly updating data.

I'm building a browers-based game that will need to constantly be updating EVERYONE'S accounts regularly; what is the best way to go about doing this? Creating a process that runs every time someone goes to a page on my site slows down the load time immensely. Do I need to create a windows scheduled task that calls this/these process(es)? It will need to constantly run.
