Forms Data Controls :: Formview Update Stops Working
Jul 22, 2010
I have a formview and data source that opens in the edit template and allows the user to update a few free form text fields. I also have some drop down boxes that allow a DOB to be built and populate another text box. All of this was working fine yesterday, and today somehow I hosed it and can not find the cause. I have rebuilt this page three times to get it working again, but I can't figure out what I am doing wrong to break it.

Here is the DataSource....

I have a formview that I open to the edit template, some textboxes are not available and some are populated by dropdown lists, and the update function works fine.
As soon as I add some logic to the code behind page for the update control, the UPDATE link on the formview stops updating my DB.

I have an Ajax timer that has an interval of 1 second and an update panel on my page. If I leave the page open and never close or refresh I notice that after 6 to 8 hours the timer stops firing. No error messages.......everything just stops. If I refresh the page everything starts working again. Are there any issues I am not aware of when running a page for a long time using the Ajax timer?

the site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

I have the follow form view:
<asp:FormView
DefaultMode="Edit"
ID="FormView1"
runat="server"
onitemupdating="FormView1_ItemUpdating">
<EditItemTemplate>
<asp:TextBox
ID="txtPrimerNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("PrimerNombre") %>'></asp:TextBox>
<asp:TextBox
ID="txtSegundoNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("SegundoNombre") %>'></asp:TextBox>
</EditItemTemplate>
</asp:FormView>
<asp:Button
ID="Actualizar"
runat="server"
Text="Button"
CommandName="Update"
/>
This formview is bound in this way:
protected void Page_Load(object sender,
EventArgs e)
{
Persona _persona =
new
Persona();
_persona.ObternerPersonaByUserIdApp(1);
List<SILPA.AccesoDatos.Generico.PersonaIdentity> persona =
new
List<SILPA.AccesoDatos.Generico.PersonaIdentity>();
persona.Add(_persona.Identity);
FormView1.DataSource = persona;
FormView1.DataBind();
}
When the page is shown, the textbox are filled correctly, this textbox are filled with the "primernombre" and "segundonombre" properties from the persona class. After this, If I change the textbox, and after click the update button, I need to update the persona class with the changes from the textboxes, then I call a ActualizarPersona method for updating the database. How can I do for update the persona class when I change the textboxes and click the update button? I try this method protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs
e)
{
}

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

Have a Formview set up to edit a single record in an SQL table. It displays the record fine, but when you click the "update" link it just appears to do a postback and nothing else.After the postback you're looking at the original record without any of the changes you just tried to make.I went to my Dataset TableAdapter and checked the UDATE query there..it works fine, I was able to change a record.My ObjectDataSource is correctly configured to use the UDATE query--I triple checked all that.

Trying to update a .NET .20 datagridview in the following scenario. A page contains a formview. The formview contains a datagridview and some other fields not in the grid. The formview has its own ObjectDataSource and the datagridview has a separate ObjectDataSource. Each ObjectDataSource has an OnUpdating event. Clicking a Save button triggers the formview update event and the "non-grid" ObjectDataSource updates without a problem. In that same event, I also want to update the grid's ObjectDataSource. Because it's a grid, this OnUpdating event has to loop through each row, get the data for that row and set the UpdateParameter values. A foreach loop can get the values, but how do I trigger the update before looping to the next row?
Should I try calling a different kind of event for the DataGridView's ObjectDataSource? Or is there a way to get all the grid's new data at once as a dataset or datatable and do one bulk update? The datagridview does not have row-level edit/update buttons. It is meant to be an all-or-nothing kind of update.

I have a FormView that that implements all templates (Insert / Edit / Item). When a user updates the form and the operation completes successfully, I want the form to be closed.
I understand that the default behaviour of the FormView is that it returns to ReadOnly mode. I also understand that I can change the default mode so the view will not be ReadOnly, but Insert or Edit. However, I want a much simpler thing - just close the view alltogether (as if it was unbounded).
I tried to change the Visible attribute of the form to False (=Not Visible) at the OnItemUpdated event, but that created consequences errors (something about viewState.... don't want to go there...)

I'm having a problem with a formview i've created. The formview itself uses a costum template to perform updates to the database. Its a form to edit Car details. One of the details is the brand. I use a dropdownlist control to let them select the name of a brand thats in our database, this passes an ID to BLL's update so the car gets updated with a brandID. My update query works perfectly when i try it directly on the database, however, when i use the formview it updates everything except the brand.
When I debug and watch the NewValues object he passes, it does contain the new value for the brandID.
btw, brand is 'merk' in dutch, so brandID is called 'MerkID', and the brandname is called 'Naam'

Is it possible to update and edit a record in Formview at the same time. Currently, the formview's default mode is set to Insert where users can add a new record to an SQL database, however, when that record is added I need that information to update another table all on one click. Is this possible with a stored procedure or a button that allows both?

I have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update using code-behind. The code is below.
AFter an insert or update, the formview makes invisible again. I want to show the formview with the newly inserted or updated row in Read-only mode. How do I do this?

I have Gridview that opens in the Edit Template with UPDATE and CANCEL links at the bottom, so the users can modify records.
When the user clicks UPDATE there is no indication that the DB was updated. I don't want to redirect the user.
What is the easiest way to provide a confirmation that the DB was updated?

I'm having a problem with a FormView control that I have bound to an ObjectDataSource. The problem is that the FormView control is not automatically filled in with the public properties of the object linked by an ObjectDataSource control when I select refresh schema. Everything compiles and I can add fields manually, but there are a lot of properties in the class and I do not want to deal with adding all the fields by hand. It's not the end of the world of course if I have to add them manually, but I'm bothered more by the fact that it doesn't act the other formviews.
Has anyone ever experienced a problem like this? I have other objectdatasource controls with other formviews that properly refresh their schemas. I noticed that in the objectdatasource control that is giving me problems, the DataObjectTypeName field is not automatically set as it is in the others. However, after adding it manually it still doesn't refresh the schema. I'm using Visual Studio 2010. Defined in .aspx page:

I have a formview that displays user info from a dropdownlist. One account may have many users, but one account Primary. I am trying to disable the Edit/Delete button in the formview if the selected ID is the account primary. The problem I get is this.
Step 1: page_load - the primary user is displayed by default, but the delete button is enabled - not right
Step 2: I use the dropdownlist to select another user (not the primary) - everything's fine
Step 3: I then select the Primary User, the Delete Button is disabled - perfect
Step 4: select another user, delete button still disabled - Not right.
[Code]....
1. As you can see my sqlSelect Parameters are bound to the DropDownList.SelectedValue, but is t seems like my if statement for comparing selecteduser to varAdminID doesn't work except once.
So to help debug, i added a label control that displays the selected userID, but on page load the label is blank. but it displays the first record on the list anyway. so if this is the reason for not disabling the delete button on page load then why later does it not reable the button when the user is not the primary, and the UserID is displayed on the label and it is not the primary userid?
