how to pass an object to the selectmethod of the objectdatasource control?
View 2 Replieshow to pass parameters to the selectmethod property of the objectdatasource control.
View 1 RepliesI have an objectDataSource which uses my stored procedure GetNotifications
And my GridView is bound to that objectDataSource
the only problem is that my stored procedure requires the variable @UserName and then returns the values for that username, but I do not know how to pass the variable to the objectDataSource, does anyone know the code for this?
I can get userName from HttpContext.Current.User.Identity.Name but how do I pass that to the objectDataSource?
Is it possible to pass a domain object as session parameter in an ObjectDataSource. I'm doing this:
<asp:ObjectDataSource ID="ParticipantsDataSource" runat="server" OnInit="SqlDataSource_Load"
SelectMethod="LoadParticipants" TypeName="SB.Web.units.Players">
<SelectParameters>
<asp:SessionParameter Name="user" SessionField="User" Type="SB.BusinessLogic.DomainEntity.User" />
</SelectParameters>
</asp:ObjectDataSource>
But I get the error message that I can't create an object of the type System.TypeCode from the string containing SB.BusinessLogic.DomainEntity.User for the property Type.

Now i can populate my gridview trough code by this: //gvwDiensten.DataSource = new BindingList<diensten>(dataManager.GetList<diensten>().ToList());But i would like to use an objectdatasource, so i created this:

But when running the page i get:
ObjectDataSource 'dsDiensten' could not find a non-generic method 'GetList' that has no parameters.
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">
</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?

I'm trying to link 2 objectdatasource together using the Control Parameter Source.However, I'm stuck at the screenshot below. The Next button is disabled.
View 1 RepliesI have a page where you can search and display other data, very simple layout. 1 Gridview and 1 objectdatasource. But i have 4 possible buttons that can populate the gridview..
i would like to control my objectdatasource from the code behind based on the button you click.
here is what i have right now.. but if possible, can this source not be hardcoded like this and only built in the code behind?

I found this site with a solution to this persons issue, but i cant seem to get mine working this way.

I have this as the code behind right now when you press the button.. what other parameter settings am i missing and is this the right order to populate them for the source to acknowledge my values?

I am going to use DetailsView control for the first time and before using it I thought I would like ask this question. Instead of using the SqlDataSource Object/Class Can i have my class to most of the functionality?In short I donot want to use the in build Sql Data Source control rather would prefer to write my own. Is it possible (I know it must be!) to write the custom SqlDataSource class.

I have an image file to be uploaded and to be updated in my database. I've already write the C# code based in a VB code.
However, I have some trouble to pass a data to be updated through DetailsView Control, by using

In VB the Code is:
e.Values(
"ImageData"
) = imageBytes
ImageBytes is an array of bytes..
I'm trying to bind both GridView and DetailsView to a single ObjectDataSource declaratively (in markup). I'm getting the error read as below when I tried to run it.
"The DataSourceID of 'DetailsView1' must be the ID of a control of type IDataSource. A control with ID 'ReservationsDataSource' could not be found."
It works when I bind GridView and DetailsView each seperately to my ObjectDataSource. Is it I can't bind two pagable data web controls to a single datasource?? or there is a trick needed to be done for this to work.
FYI, I'm trying to create a Master/DetailsView of my data. DetailsView of my application should show the record selected in GridView and it should be editable.
I am using a gridview to select a record and control that record using a details view. I am using a class based objectdatasource to link the data for select, update and delete. Sofar the select works but the update fails. Here is my error message:
ObjectDataSource 'odsDetailsView_1' could not find a non-generic method 'UpdateSet' that has parameters: setId, TYPE, iHPlayer, iAPlayer, iHRuns, iARuns, iH8Break, iA8Break, iHe8s8, iAe8s8, iH15BRn, iA15BRn, iHWins, iAWins, SET_ID, MATCH_FK, HOME_MEMBER_ID_FK, AWAY_MEMBER_ID_FK, HOME_TABLERUN, AWAY_TABLERUN, HOME_8BALLBREAK, AWAY_8BALLBREAK, HOME_E8S8, AWAY_E8S8, HOME_15BRN, AWAY_15BRN, HOME_TOTALWON, AWAY_TOTALWON, HOME_POINTS, AWAY_POINTS, LOCKED, GROUP_FK.
The first group of parameters have lower case letters and they come from my objectdatasources update method parameters. The second group of parameters are all capitalized and they are the fields in my SQL database table (and I don't know how they wound up in the error). This might be a clue.When executing the code my class method never gets the chance to execute because the error pops up before the code gets there.

I've written a class that contains Select- and Update-Methods for an ObjectDataSource. The UpdateMethod receives an instance of a called class. My problem is, that only properties that are Bound in the DetailsView are set, the others have their default value.Here's my code:Class declaration:
public class Foo
{
public string Prop1 {get;set:}
public int Prop2 {get;set;}

I've created a query in the table adapter for retrieving customer name based on the first letter. The query is executed fine, and the output is the customer name and ID. A Customer BLL accesses this query, and sends the results to an objectdatasource. This control is configured to use this customer-by-letter query. However for some reason, this objectdatasource does not bind the name and ID, but instead all the other fields produced by the main query in the table adapter (i.e. name, address, phone, etc....).
I'm probably not configuring something correctly, but I'm not sure what.
