Forms Data Controls :: Delete Gridview Row With Objectdatasource?
Sep 21, 2010
I get the following error when trying to delete a row in a gridview. The error is strange, since I dont pass 2 parameters as far as I can see.This is the error and the code is below:
Server Error in '/' Application.
ObjectDataSource 'odsRooms' could not find a non-generic method 'DeleteRoom' that has parameters: id, locationid.

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

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="photoID"

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

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 ?

Could you teach me how to make girdview pass my object (with all it properties) to my ObjectDataSource delete method please?So far the object received by the delete method has only the datakey value, other properties are null.From this article indicates that this is default behaviour - ttp://www.manuelabadia.com/blog/PermaLink,guid,c72852ae-1fdd-4934-a715-f565ceaf21cc.aspxBut i need the other properties pass to the delete method too so i can do other thing before I actually delete the record.

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.

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.

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.

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

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.

In my application there are some GridView(GV) controls. Deletion is already implementd in GV's RowCommand.
Now GVs are bound to ObjectDataSource(ODS). So, whenever a deletion is performed I run into situation like
"System.NotSupportedException: Deleting is not supported by ObjectDataSource.........."
So, I have created a Delete method in the DAL that does nothing and hooked it up to the ODS via its DeleteMethod property.
My question is, is it possible to suppress the Delete event of the ODS? So, when something is deleted thru GV, it will be handled in the GV's RowCommand and ODS' Delete event handler is not called.

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.

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.

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.

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 -

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.
