Does anyone have an example of a formview and a gridview master detail relationship in c# ?
The gridview datasource is a datatable and the gridview is inside of the edititemtemplate of the formview.
In what event of the formview do you bind the gridview datasource?
i have a formview1 in edit mode within a modal pop up extender and Update Panel
The update statement works but on the page is a gridview1 where I want
to display the new values.
I have added the below in page code but it still does not bind
the Gridview with new values when after I click UpdateButton in Formview - Only when I refresh the page.
protected void FormView2_ItemUpdated(object sender, FormViewUpdatedEventArgs e)
{
GridView3.DataBind();
ObjectDataSource50.DataBind();
}
I have a Formview residing inside am Item Template of a Gridview. The formview is not populating, and I am pretty convinced that I am not passing the parameter properly from the Gridview to the Formview. I have listed the relevant code only, so that you can scan though it easierGridview tag:

since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.
[Code]....
Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
Is this a known change or a bug of ASP.Net 4.0?
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?

Using Visual Web Developer Express 2010 with ASP.NET 4.0.
I have a FormView and I want to set a default value from the database. I can't get it to bind to the value in the database. My FormView looks like this:
[Code]....
The EditItemTemplate does not even load when I click the edit button on my FormView control, but I don't get an error message either.
I have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.
When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.
I just started working with LinqDataSources and I was wondering how you retrieve values in a FormView DataBound Event.
With an ObjectDataSource I believe you can grab them like:
[Code]....
Is there a similar way to acheive this with a LinqDataSource?
I've seen this before, I fixed long time ago and now cannot remember how I did :) My store procedure won't update the record because the sql field 'itemId' is being passed as ZERO always.

I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView
ID="fvTicketUpdate"
runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's
code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo :
System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.
I have tried to query a table with an xml column by using XQuery and I can't get the Select to work.
All my knowledge/understanding of the subject comes from this MSDN article:
[URL]
so I am probably overlooking something minor:
I tried this query Select col1, Phone.Query('element CellPhone {I am not sure about what goes here} I tried {data('Phone/cellPhone} from aTable Where Phone.Exist('/Phone/cellPhone/text()[contains.,"412-8977"]') = 1 This syntax is definitely not fun.

I've got a FormView control on a page. Its default mode is insert, since the intent is to have the user enter a record, save it, and then do something else. I've written a stored procedure to insert all of the data into 5 tables. 1 of the columns inserted is default, in SQL Server 2005, as an INT column, which is an IDENTITY column. After it inserts the record into the primary table, using a secondary stored procedure, it retrieves the newly created INT value, and then the primary stored procedure inserts records, using the new INT, into the other 4 tables. This is working fine. The primary stored procedure, which is called by the SqlDataSource on my .aspx page, defines this parameter as an output parameter:
[Code]....
In the FormView's ItemInserted event I'm trying to get the value from the FormViewInsertedEventArgs e parameter like this: [Code]....
However, the result returned is 0. Huh? That cannot be, because the new INT value created is something like 145000. Why am I then seeing a value of 0?
I have a user control that displays a list of records. Users have the ability to open an embedded user control with a FormView to either add a new record or to edit an existing one. The UserControl with the FormView has a button that closes and hides the user control.
If the user control with the FormView is opened to edit a record, the code works fine. But if the UserControl is opened directly into Insert mode, the code craps out

Can someone see what is wrong or missing?
What do I want to archieve: Just update the subscription's credits and its type: Upgrade, Prolong.
-edit-
New finding: I added 'onitemcommand="fvSubscriptionEdit_ItemCommand"' to the formview and a corresponding event method with a simple code that throw a exception(just testing) but it doesnt enter the method but does whine when the method is missing. So why does it whine if the method is not there but doesnt enter the method if it does exist? I presume that this is the same problem.

I am trying to validate data using the OnItemUpdating event on a FormView control. The event is fired when I click the update button but

ValidateForm(Object sender, FormViewUpdateEventArgs e)
{
string val = e.OldValues["txtDate2"].ToString();
}
I've always understood that it was best practice to add event handlers in code in the page load event thus:
Button1.Attributes.Add("onclick", "alert('Hello');");
rather than "onclientclick=somefunction()"
My question is, how do you add event handlers to formview controls where the control(s) may only be on the edit template and not on the insert and read only templates.
Simply putting the code in the page load would produce an error.
Where should the statement be placed in such scenarios?
