DataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?
Oct 18, 2010I 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">
</asp:ObjectDataSource>
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?

May 21, 2010I have a 2 FileUpload controls.
Once the user selects a file in the first control, I want to set the default value for the 2nd control to be the value from the first control.
For example, if it were textbox controls I would just use TextBox1.text = TextBox2.text.
How do I do this for FileUpload controls? I tried a few different properties, such as FileUpload1.FileName = FileUpload2.FileName but I get an error saying that they are Read Only.
Web Forms :: Hide FileUpload Control?
May 7, 2010I would like to simply have an image button on my page that would show an image that says something like "Upload File".When the user clicks the button I would like for it to automate popping up the "select file dialog" exactly like the "browse" button does on the FileUpload control now. Then if the user selects a file and click "OK" I want to do a post back where I can then initiate the upload. If the user clicks cancel from the dialog I would do nothing.So all I am trying to do her is make it so that the user does not see the text box for the file name and replace the plain old browse button with an image and do a postback if they click ok from the dialog.

View 6 RepliesWeb Forms :: Fileupload Control - How To Set Upload Path
Sep 28, 2010I have a site that uploads multiple PDF files from a CD from one specific computer and that computer is the server that will store the PDF files. I want to do this without having doezens of fileupload controls as the number of PDF files vary from CD to CD.
My problem is that I want the whole process automated. The site will read the names of the PDF files on the CD to the SQL server, which will match, parse, and delete unneeded information with the actual names in a comma delimited textfile. I have that all completed, but i'm only getting the filenames of the PDF and no the contents of the PDF's themselves (They all show 0KB). I am certain that the problem is that i'm pulling from Directory.GetFiles and it's only saving the filenames instead of the files themselves. Is there any way to set the upload path for the filecontrol?

Web Forms :: FileUpload Control Loses Value On Postback?
Sep 11, 2010I'm having a little problem with my file uploading. Does anybody know how to maintain the value in the FileUpload control between server posts?
I have a form which, among other things, uploads a file. I am using an ileUpload control (created dynamically) to let a user browse their PC for a file and then using the SaveAs method to upload the file to the server.When I'm selecting a file and Click on Next button for processing then selected file is lost.
Same is happening with me with HtmlTextArea (dynamically generated) , the problem was that I was not again re-initializing the controls after postback. What I did is re-initialized it in Init method of placeholder (as I have created/placed all dynamic controls in placeholder ).
But this thing is not working for fileupload control. I found solution in one of the forum is that "use hiddenField Control to transfer the selected file from the client to server"but this mechanism will only help to retain the name of file
in a hidden variable and the FileUpload1.PostedFile.SaveAs(filename) will not work bcz of absense of object (fileupload1).
here is code:

I have done almost the same in different test project , it works . I dont know whats wrong?

Web Forms :: How To Get The File Path Using The FileUpload Control
Sep 15, 2010The requirement is that the whole original file path be saved to the database; for example: L:folder1folder2xyz.doc. However; the FileName property of the FileUpload control will only give "xyz.doc". We are interested in obtaining the full path only and really not interested in using the control to do any upload.
Is there any way to get the full path? We would like our user to be able to browse to the target file instead typing into a textbox because the folder name could be very long and several levels deep in our organization.
