Forms Data Controls :: Updating Checkbox Value Through ObjectDataSource Update Method
Jan 4, 2011
I am very new to updating the datasource using ObjectDatasource. I have a checkbox on click of update the update method triggers but though teh check box is checked, the value is updated as false.
<asp:TemplateField HeaderText="IsPrimary" SortExpression="IsPrimary">
<EditItemTemplate>
<asp:CheckBox runat="server" ID="chkIsPrimary" Checked='<%# Eval("IsPrimary") %>' />
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Remarks">
<EditItemTemplate>
<asp:TextBox ID="txtRemarks" runat="server" SkinID="longTextBox" TextMode="multiLine"
Text='<%# Bind("Remarks") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>......................

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.
Here is my objectdatasource:

Here is my detailsview:

Here is my class update method constructor:

I have a datarepeater control on my form. I have a method for updating comments, but I would like it to be exectued when a user clicks a checkbox (inside the datarepeater). The checked value is being "bind" to the checkbox control. Can I use the built in Update Method tied to the objectdatasource?

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?

Here is the "Update" method which is not updating.
It works if I remove "@original_UnitPrice" and "@original_OnHand" parameters from the "WHERE" clause.

I'm trying to figure out if it's possible to use an ObjectDataSource Update method with a table-valued parameter. Here's my ODS:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
DataObjectTypeName="TestProject.MyTestDataTable"
SelectMethod="GetTestData" TypeName="TestProject.BLL.TestBLL"
OldValuesParameterFormatString="original_{0}"
UpdateMethod="UpdateTestData">
<SelectParameters>
<asp:Parameter DefaultValue="65" Name="testId" Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>
I bind this to a GridView but I'm not looking to edit row by row. Instead my GridView has a bunch of TemplateFields with textboxes. I also have a Button that when pressed, invokes the Update method of the ODS. So then the "UpdateTestData" function in my TestBLL is called. This looks like this:
public void UpdateTestData(MyTestDataTable dt)
{
QueriesTableAdapter qta = new QueriesTableAdapter();
qta.UpdateTestData(dt);
}
At run-time in debug, it seems like the object for the signature above is not populated with the data from my GridView.

I have a gridview with the ObjectDataSource and the Update does not work. When I click on Edit, I go to Edit mode but Update will not work at all. No errors. I do believe that it is in the RowUpdating method but cannot figure out how to call the method UpdateBook from the BookManager BAL.

Put in Breakpoints and it is getting to the RowUpdating but will not update.

i have been following the asp.net data access tutorials on this site. When i try to update, nothing happens. I believe the problem lies with my wrong coding on the BLL part. I'm using table adapters. Could anyone point out what iswrong with my code or tell my what the correct code is?

I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below

I'm doing research on framework development for my company. SInce I will be developing a framework I can not simply declaire all my control in the code in front. Receiently I've been having trouble binding the controls from my ListView to my ObjectData Source. Basicly the properties in my DataObjectTypeName are not populated when the ObjectDataSource "Update" command is thrown. I recieve no error, I just get null values. All I need is an equivalent to this statement for code-behind ...
<%# Bind("AbstractText") %>This would solve all my issues. Ofcouse I will most likely need to bind the control's ID somewhere but that is not an issue. How do I Bind a control to a property in my DataObjectTypeName from the code-behind?

So I am uding a GridView bound to a SQL data source.
I have a template feild bound to a SQL BIT
<EditItemTemplate <asp:CheckBox ID="chkSelected" runat="server" Checked='<%# Bind("Selected") %>
The original Item Template was Enabled ="false" I changed this so that you did not have to set the row to a state of edit in order to just select a row. I enabled it so that you could "select" any row with out putting it in a state of edit. the only value changing is if its selected or not. What i am trying to do is use the Data Source Update method to update the bit in the database based on the check box. Currently Update() returns 0. I believe this is because the row/feild is not marked as changed so the Data Source does not see it as something that needs to be updated.
What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes. If all rows are updated this is acceptable as well. I know this is a super simple solution but i have been out of the .NET for a little bit.

In trying to improve 'user experience' with a GridView, I have an administrative application where a GridView is displaying records from a SQL table. One of the columns is a bit column, and is displayed as a checkbox in the GridView. I want the user to be able to simply check or uncheck the box while viewing the GridView, and the value in that column for that record is immediately updated. So I set AutoPostBack="true" on the CheckBox in the GridView's Template Field.
But tests are indicating that the column value is not actually getting changed, even though the page appears to post back and displays the newly checked (or unchecked) checkbox correctly. But if I check the SQL table directly the column's value has not changed.

I have a simple table. (with PK). I have created a tableadapter that selects all fields and filters with a control parameter. This works fine. The results are displayed within a DetailView control. All okay up to this point. I have then enabled 'Editing'.I can then click on the edit and change the text, but when I click the edit button the page updates but the value has not changed in the database?

I have multiple gridviews on one page that connect to the db with different sql datasources.
They each show records with differents "status's"(this is a column in my table). When you update the status on one record I'd like it to display straight away in the other gridview. At the moment I have to reload the page after the update in order to see the changes. Can I set the update buttons in the gridviews to postback after updating?
