Forms Data Controls :: Access A Method Of Entity Class From A FormView?

Feb 24, 2010

I have a Customer database table with a text field named customerPicture with the name of the JPG file.

I have made a Customer Entity class with the LinQ to SQL Designer.

I also have a FormView displaying Customer instance binding with a LinqDataSource.

My problem is:

I want to make some modifications when some control want to bind the customerPicture field.

For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.

I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.

If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?

DataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?

Oct 18, 2010

I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):

Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub

And here's the markup for the datasource:

<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">

My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:

Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function

When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?

Forms Data Controls :: Checking A Value In A Method Before It's Inserted (Formview C#)

Nov 18, 2010

I've been pickling my brain trying to do this for a couple of days but to no avail. I have the following in "FormView1" which I'm just using in insert mode:

<td class="style4">
<asp:TextBox ID="urlTextBox" runat="server" Text='<%# Bind("url") %>' CausesValidation="True" Width="200px" />

I'd like the contents (i.e. whatever the user wants to insert) to be passed to a method where it will be checked against any existing values in the database.

Forms Data Controls :: GridView.RowDataBound Equivalents In DetailsView And FormView Method

May 4, 2010

Is there an equivalent of the GridView.RowDataBound event for the DetailView and FormView controls in ASP.NET 3.5?I need to manipulate data after Selecting it from my database, but before it gets presented to the user. I've read the documentation but I think I've missed something because I can only find FormView.DataBound which is called after the entire control has been data bound. Something like an ItemDataBound event would be what I need....?!?

Forms Data Controls :: Using Formview, Tables, And Access Database Along With The BLL & DAL Model?

Jul 7, 2010

Really new to C# & Web developing - but have used the DAL & BLL model from a number of the turorials. Have a situation that I not sure the best way to accomplish. I have an application dealing with courses, books, etc. utilizing an Access Database. All was going well in creating an on-line catalog using Formview and tables to display the db values stored in the Course Table (Course ID the key). User is able to use dropdown list to locate the course - dropdown list showed the Course Nbr & Name, but used the Course ID to get the detail. This issue appeared when they introduced a Prerequisite field in the Course Table. This contains the Course ID of the prerequisite course, but they want to display the Course Nbr and Name in the table field. So today it show 18 (Course ID) and they want B101 Intro to Biology. Hope I have provided enough information of what the code looks like below


<asp:FormView ID="FVGeeralidades" runat="server" DataKeyNames="ClaveAsignaturas"
<asp:TableRow ID="TableRow5" runat="server">
<asp:TableCell ID="TableCell11" runat="server" HorizontalAlign="Left" Text="<STRONG>1.6</STRONG> Prerrequisito"
<asp:TableCell ID="TableCell12" runat="server"></asp:TableCell>
<asp:TableCell ID="PrerrequisitoValue" runat="server" HorizontalAlign="Left">
<%# Eval("AsignaturaPrerrequisito")%>

Here is also the OBJECT DATA SOURCE
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" OldValuesParameterFormatString="original_{0}"
SelectMethod="GetCourseByCourseID" TypeName="CoursesBLL">
<asp:ControlParameter ControlID="DDLCourse" Name="CourseID" PropertyName="SelectedValue"
Type="String" />

Forms Data Controls :: ObjectDataSource Cannot Access GridView Control Inside FormView

Apr 16, 2010

Basically as the title of this thread states, I have a FormView that has a GridView inside it and my ObjectDataSource that populates this grid cannot access the Grid.

The Control Id needs to be the name of the Grid I want to access, however through the 'wizard' the Control parameter drop down cannot 'see' the grid I need, only the FormView that is in.

I have tried numerous ways to get round this and am struggling now..

I've tried the following...



ControlID="<%= GetNameOfGrid %>"

and numerous other attempts that also failed that I now cant remember...

Of course the above code is not valid because I don't think you can put GridViewRowEventArgs within the method like that. I don't want to put it within a event handler because that even handler is doing other things. I want to be able to call this seperatley.
