how to get value to the objectdatasource from datalist itembound method
protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
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

My Business Object code is below :

My Data Access Layer Code is:

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 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 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?
My Business Logic Layer has AddItem method that add's to Items table in db along with an entry in Balance table.AddItem method uses two TableAdapters Items & Balance. Both these have corresponding Business Objects as Item and Balance.
Here is the AddItem method :

ASPX Page with DetailsView & ObjectDataSource
[Code]....
Now executing this page generates error as
ObjectDataSource 'ObjectDataSource2' could not find a non-generic method 'AddItem' that has parameters: _item, _balance, ItemName, GroupId, CategoryId, AuId, Rate, TotalStrScale, OffsStrScale, OffsAE [code]...
i have this class
class MyDal
{
IList<MyData> GetAll(string orderBy, , int count, int firstIndex, out int totalRowCount);
}
i'm using an objectdatasource with MyDal to bind values to a gridview.
i want know if there's a way to configure the objectdatasource to use the parameter totalRowCount without calling the SelectCountMethod.
I've an ObjectDataSource & its datasource from typed dataset which is bind to 3 textboxes.
One of that textbox text concatenate with other two textboxes values.
Some thing like this,
textbox1.text=textbox2.text & textbox3.text
How can I customize my insert query for this?
I could not see the insert query in my objectdatasource.
Here is the "Update" method which is not updating.
It works if I remove "@original_UnitPrice" and "@original_OnHand" parameters from the "WHERE" clause.

How and where can I get the returnvalue from my "DeleteGuestById" method to show the right error message to my user?
I have this:
Protected Sub gvGuestlist_OnRowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvGuestlist.RowCommand
If e.CommandName = "DeleteGuest" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim data As DataKey = gvGuestlist.DataKeys(index)
Dim GuestId As Integer = data.Values("id")
odsGuestlist.DeleteParameters.Clear()
odsGuestlist.DeleteParameters.Add("id", GuestId)
odsGuestlist.Delete()
End If
End Sub
In my BLL:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Update, False)> Public Function DeleteGuestById(ByVal ID As Integer) As Integer
Dim returnval As Integer
GuestlistAdapter.DeleteGuestById(ID, returnval)
Return returnval
End Function
I think I have to be in the ObjectDatasources' "OnDeleted" method but I have no what code to place there.
error "ObjectDataSource 'ObjectDataSourceCaseDetails' could not find a non-generic method". I have an update method and my ObjectDataSource is hooked up to the method in my BLL. review my code below

In my application at some places we have used ObjectDataSource and at other normal method calls to retrieve data.My question is then what exactly are the benefits of using ObjectDataSource ?In the example below "CODE ONE" makes a call to the Business Layer and then Binds the results to the Grid abd "CODE TWO" is using ObjectDataSource to do the same.Then how is ObjectDataSource better?
SuitableApplicant sa = new SuitableApplicant();
IList<HD.Recruitment.SuitableApplicant> list = new List<HD.Recruitment.SuitableApplicant>();
list = HS.Recruitment.RecruitmentService.GetSuitableAppls();
GridView1.DataSource = list;

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:
[Code]....
</asp:ObjectDataSource>
But when running the page i get:
ObjectDataSource 'dsDiensten' could not find a non-generic method 'GetList' that has no parameters.
I try to update the detailview control. got this error messsage.
ObjectDataSource 'odsDetail' could not find a non-generic method 'Update' that has parameters: hospitalID, hospitalName, taxID, address1, address2, city, state, zip.

here's my edit function

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.
The problem is that i have a search page. Access Database holding the information. I have a Access Datasource on the page with a Datalist to show the data. I need to find a way on setting it up to says "Sorry no results found" when the is no results. i am unsure on how to do this though.
Below is my datasource and datalist

Am building a Form for out intranet that runs on ASP.NET and C#, it is to be a survey from a SQL database. I have the connections setup can pull informations/Questions from the database. I am having a problem with setting up radio buttons within a datalist, ive never done this and i know they require unque names.
It is to be 4 radio buttons per question where only one can be select, i know how to group just not via a datalist with unique names
How can I do paging with datalist if that datalist is populated with inputs coming from a querystring?

I am trying to place a datalist inside datalist. I managed to place a datalist inside gridview but not datalist inside datalist.
Below is the code I am using to bind the datalist into the master gridview, I am trying to change this code in such way it will be right for datalist inside datalist but so far I did not succeed.

i have a datalist . that is contains 7 columns in repeat layout .when i have more from 7 columns , datalist style is normal .but when i have smaller than 7 columns ! data list style is not normal,
because there are some empty columns without specific schema.
How i can make a datalist > when i have 1 columns in my datalist my first layout width be 100% ;
and dont show some empty layout ?
I have this ASP.NET code:
<asp:DropDownList
ID="ddlBrokers"
runat="server"
AutoPostBack="true"
DataSourceID="srcBrokers"
DataTextField="broker"
DataValueField="brokerId"
/>
<asp:ObjectDataSource
id="srcBrokers"
TypeName="DatabaseComponent.DBUtil"
SelectMethod="GetBrokers"
runat="server">
</asp:ObjectDataSource>
My DAL code:
public DataTable GetBrokers(bool? hasImport=null)
{
SqlCommand cmd = new SqlCommand("usp_GetBrokers");
if (hasImport.HasValue)
cmd.Parameters.AddWithValue("@hasImport", hasImport);
return FillDataTable(cmd, "brokers");
}
When the form loads I get this error:
ObjectDataSource 'srcBrokers' could not find a non-generic method 'GetBrokers' that has no parameters.
Is it my optional parameter that is causing the problem? How can I workaround this? Is it possible to have optional parameters with declarative ASP.NET code?

for some reason asp.net cals SelectMethod2 with (0,0,"") parameters and does not call GetCount.
