Forms Data Controls :: DetailsView's ObjectDataSource Update Method Fails?

Jan 15, 2011

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:

Forms Data Controls :: GridView And ObjectDataSource - Column Is Not Shown In The GridView's List ?

Feb 9, 2011

I'm facing a wierd problem with GridView and ObjectDataSource. I bind GridView to my business objects via ObjectDataSource. Everything was working fine until I decided to add a new field in my buisness object and wanted to add a column to GridView to show it. Somehow that column is NOT shown in the GridView's list of available columns. I have tried refreshing schema, rebinding, etc. I'm using GridView inside a user control which is used as a web part. Does that make a difference ?

Forms Data Controls :: Edit GridView Row With ObjectDataSource

Sep 21, 2010

I have a grid that receives products over a GetList methods via ObjectDataSource. The Product class contains also a Object Supplier. If I change in the drop down list of the grid the supplier for a product and I click update the ID of the suppliier is still the same. I have debugged the call of the update method and checked the parameter in the product object. I wrote the following code in the SelectedIndexChanged event and the text box shows the right id but not the update method.

DropDownList supplier = (DropDownList) sender;
txtTest.Text = supplier.SelectedValue;

Here is the code of my grid view:

[Code]....

My Object Data Source calls the following Update Method:

[Code]....

The next work around idea would be to call the update method manually in the Update Event of the grid view.

Forms Data Controls :: OnUpdating Using ObjectDataSource And Gridview?

Feb 9, 2010

I've been working a gridview that uses an ObjectDataSource to perform either select, insert, delete or update. I was able to get everything to work correctly with the GridView except when it came to performing an update. My first issue that I came across was that it was tacking on two extra columns or fields that I didn't really expect. The function being called (SavePipelineUser) only expected 4 parameters and was getting 6 in total. This was occuring even though I had placed OldValuesParameterFormatString="original_{0}" or OldValuesParameterFormatString="{0}" within the GridView's attributes.

Ok, So I was able to resolve this issue by going into the OnUpdating event in the ObjectDataSource and doing the following below. This effectively removes the additional parameters from being added. However, I now have a new problem. There doesn't appear to be any values actually being passed into this method. So, while no errors appear, nothing gets updated. Can anyone explain to me why my values are not being carried forward? I've spent about a day and a half working on this issue and was able to get around this by just going with the GridView's RowUpdating event and grabbing values from grid to manually get it to update. While I'm very happy for anything to be working after so much time, I still feel like this is a bad hack for this to work. I have a hard time fathoming why this seemingly simple use of the GridView on my part has turned out to be very complicated. I'm extremely leary now of using the ObjectDataSource object for anything if it's going to be this much of an effort.

<!--html code-->
<asp:GridView ID="gvPipelineUsers" runat="server" AllowPaging="True"
AllowSorting="True" DataSourceID="objCommon" AutoGenerateColumns="False" ShowFooter="True"

Forms Data Controls :: GridView And ObjectDataSource Filtering?

Jan 27, 2010

I'm using a GridView with an ObejctDataSource. The data is provided by a business object and not a DB. It returns a list of people and each person belongs to a group. Now I need to filter data. For example, I need to return list of people in specific groups. How can I specify a list of groups to be able to filter the data ? Could I use SQL like syntax ? I understand the filter expression works only when data is returned as a datatable. But in my business object I maintain data as hashtables and return as List<PeopleInfo>. Do I need to return list as datatable instead ?

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.

Forms Data Controls :: Gridview (bound By ObjectDataSource) Sorting

Aug 31, 2010

I have a gridview being data bound by an objectdatasource which points to a BLL/DAL. I have paging and sorting enabled within the gridview. I have the fields configured in the look/fell I want from a templatefield. This templatefield has the sort expression (date) I want things to be sorted by. All this works as it should and I have no issues with it.But, the issue is that when I click on the header to sort asc/desc by date, I have to click on it twice for it switch to descending order. E.g. I hit the webpage and it lists all the information in the gridview, sorted by date, ascending order. If I want to sort by descending order, I have to click the date header twice in order for the gridview to sort the information in descending order; the clicks cause a post-back and the whole screen is refreshed.

Forms Data Controls :: Sorting A GridView That Is Populated By An ObjectDataSource?

I am having some difficulty enabling sorting on a gridview that has data in it that has come from an objectdatasource.

The AllowSorting="True" function doesnt work for ObjectDataSource so I need to find a work around...I am guessing that I will need to do something in code in order to get this off the ground.

Forms Data Controls :: GridView Inside FormView With ObjectDataSource

Mar 20, 2010

I have an ObjectDataSource giving me data similar to: OrderNumber OrderDate OrderValue OrderItems The first three are simple data types and the last has multiple occurrences of another class: OrderLineNumber OrderItem OrderQuantity The ObjectDataSource will only contain one row (which might make things simpler). So, there will be one OrderNumber, OrderDate and OrderValue; and then several occurrences of OrderItems (each containing OrderLineNumber, OrderItem and OrderQuantity).

I am displaying OrderNumber, OrderDate and OrderValue in the FormView - that work's fine, as expected. I have placed a GridView within the FormView and am failing miserably to get it to bind to OrderItems. I have tried the obvious things like specifying "odsWhatever.OrderItems" as the DataSourceID for the GridView, but to no avail.

Forms Data Controls :: GridView Bound To ObjectDataSource Not Populating

Jan 28, 2011

VS2010 Ultimate ASP.NET 4.0 Web Appliction project

I have a simple aspx page with a GridView Bound to an ObjectDataSource utilizing a class object that returns a DataView.

There are no errors generated, but the GridView does not display any rows. If I check the return value of the ObjectDataSource in the Selected event in the Immediate window (?CType(e.ReturnValue,DataView).Count), there are 51 rows. However, (?Me.GridView1.Rows.Count) shows 0 rows. The exact same page in VS2008, ASP.NET 3.5 works fine. how to get the GridView to display the rows? What has been done to the GridView in 4.0?

Page and code below -

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm2.aspx.vb" Inherits=".WebForm2" %>

Forms Data Controls :: Binding Both GridView And DetailsView To A Single ObjectDataSource?

Jan 15, 2010

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.

Forms Data Controls :: Finding The Last Row Inserted Into Gridview Via ObjectDataSource Control

Feb 16, 2010

I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.

My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.

I'm thinking maybe last data key, but based on the sort that would be accurate.

Forms Data Controls :: GridView - Add An ObjectDataSource To The Mark Up - Binding Controls

Dec 16, 2010

I have a Gridview in the markup and I add an ObjectDataSource to the mark up which will be the gridviews data source. Is this a redundant way of binding controls? I believe using this method is good for small sites with little customisation etc. but, for large sites (multi lingual, hundreds of pages etc) I have been taught to create the controls in the mark up or code behind, then bind the controls on PreRender in the code behind. My new boss thinks this method is old school and the current way of using an objectdatasource in the mark up is the best way to do it.

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="FormView.GridView1"

ControlID="FormView.FindControl("GridView1")

ControlID="<%= GetNameOfGrid %>"

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