Forms Data Controls :: FormView Won't Do An Update
Nov 15, 2010
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.

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.

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'

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.

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 have a Formview control that has several lookup fields. The value is an int ID but the textfield is the name, e.g. value = StateID, displayed text = StateCode)
If the user leaves that field blank, I get a Server Error when attempting to Update: Failed to set one or more properties on type orgOrganization. is not a valid value for Int32.
In the table for the LinqDataSource which provides the data for the Formview, all fields except the text field OrganizationName allow Nulls.
Does anyone know why this might be happening? I tried a test which just has the numbers, no lookups, and get the same result.

I am *VERY* new to ASP.net. This may seem simple to you all, but I'm really lost. I have a small sized page with three text boxes (part of the InsertItemTemplate) of a formview, and a slightly modified link the system generated to submit the data to be inserted in the database:
[Code]....
If this page is run, it inserts the data into the database fine, clears the form and sits there. I want it to return a simple "Thank you" page in a window of the same size, with a Close Window buttom at the bottom to close the window:
[Code]....
When I set the postbackurl property on the first page, everything appears to work, except the write is never done to the database. If I remove the postback, it works as it did previously.

I have created a formview with 4 dynamic controls fields that LINQ to a database.
rentfoodutilitytotal
There's an event handle for each of the first three fields whenever a text change with following codes:
' extract textbox from both SubTotal and the modified field
tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit")
tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit")
'extract string from those textboxes
txtSubtotal = tboxSubtotal.Text
txtModifier = tboxModifier.Text
'convert text to double and add them together
Double.TryParse(txtModifier, dblModifier)
Double.TryParse(txtSubtotal, dblSubtotal)
dblSubtotal = dblSubtotal + dblModifier
'post the changes back to SubTotalTextBoxEdit
'totalTextBoxEdit
'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal)
'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.

I have a page that is using the value from a textbox on a previous page to populate a formview. When I generate the Insert, Update and Delete Statements in Web Developer the edit brings up a blank page and the insert and delete don't work. It works if I just create the formview on a page and hardcode the value in the select statement then the Edit/Delete and Insert works.

As noted above everything appears fine until update button is clicked. The page refresh is blank - the formview displays no data. What's strange is that when I go back to that page the formview will not display data. The data is in the database, updated as expected. I tried rebinding on postback, nothing. The empty template is displayed.
