I have a 4 formviews present on a page. Three are updating to the DB without issue when the update link button is clicked. One is not. I have the DataKeyName set and still it doesn't save.

I am using a stored procedure for a sqldatasource to update a formview. I believe that I am passing the Obligation_Status value correctly to the stored procedure but the oblgation status field is always updated AS NULL in the database. Does anyone know what I am doing wrong?

One of the fields on my formview is a dropdownlist. When I go into edit mode the dropdownlist gets set to the correct value and works fine up to this point. Problem is I just can't see how to get the newly selected value of the dropdownlist to persist to the database when update is clicked. The DDL is a category list and I want to allow changing of the category for each record. Like I said I have it working so it displays the correct category for the record but if I change the DDL (change category) the new selected value doesn't get updated in the database. It just keeps using the binded value that was originally assigned to the selected value of the DDL. see code snippit
[Code]....
The above snippet is how I am binding the DDL. Now to not bore you with a ton of code paste I use various events of the formview to make sure the value displayed in the DDL is correct for the record that I am viewing at the time. All that works just fine. Where I need some pointers is the when I enter edit mode and change the DDL from say fire to ice it isn't getting persited to the database, all other info in the record gets updated just fine but the DDL never changes. I have tried several angles to getting this working and TBH my brain is yelling BREAK TIME.

I have a linkbutton in a gridview. Now what i did before is have a select on the gridview and when that was clicked it activated the indexchanged event and i was able to get the current datakeyname. Is there a way to get the current datakeyname for that row when the linkbutton is hit.

I am making a message module in asp.net with database of sql. i have made a gridview and enabled selecting. and a form view is synchorised with grid view on selecting. i am writing update sql but could not get a way to take data on Gridview or Formview to compare the record in sql database.
this is my page view

This my vb code
I have a web page with a gridview & formview (master/detail relationship) combo. On page load the gridview shows all records from a SQL table. On my page I have a button that when clicked shows the formview in Insert mode to allow users to add a new record to the data. I have also added a column to my gridview that has a link. When a user clicks this link it hides the gridview and shows the formview in edit mode with the detail from the record selected from the gridview.
In my formview I am using a listbox control to allow users to select multiple values. The choices in the listbox are populated by a SQL data table. I have successfully written code to post the selected listbox values to my SQL data field during Insert. When the user selects a record to edit I have code in the databound event to select values in the listbox from the choices based on the value in the sql data field. This works as well. My problem is that I cannot figure out the correct code to update my SqL data when a user is editing the record and makes changes to the selected listbox value. I have included my design code for my listbox in my formview edittemplate and also my behind code that I have attempted.
<td
style="width: 454px">
<asp:ListBox

I have a strange issue with the FormView. After working through some issues getting the update to work (as this is my first experience with FormViews) I now have a new issue. After I perform an update, and the FormView updates and returns to read mode, if I hit F5 (refresh) the FormView performs another update to the datasource, despite the fact it is read-only mode and none of the fields on the screen are editable.
I would think that a refresh in read mode for the FormView after an edit would simply refresh the data from the database, not perform another update. Again, the FormView is in Read Only Mode, but a refresh is creating another Update event (which I can debug and see if I break in the ItemUpdating event). This only happens after I perform an edit, not when the page initially loads.
I have an access database where when the record is updated I would like to automatically check a box and update the date to the current date in an Access 2002-2003 database. I've tried this for several days without any resolution and can't find anything that works on the net. ...I'm new at this.
I'm using VWD 2005 Express and Expressions Web 3.
Here is a short version of the code.
[Code]....
I have this problem everytime I change the select command to a custom command, and I do not know what is causing it.
My Formview will not update when i hit the update button, page refreshes but I get the same info, not the updated info. I set up my DataSource to CRUD only one table, then change the select statement just for the ItemTemplate of the Formview, leaving the rest, but it will not update
I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?

I am handling the row databound event. I need to bind a dropdownlist which is present only in the EditItemTemplate.
So it is throwing:
DropDownList ddlAccountingPeriod = e.Row.FindControl("ddlAccountingPeriod") as DropDownList;
UIControlHelper.BindApprovalPeriod(ddlAccountingPeriod);
this throws a null exception as the dropdown is not present in the ItemTemplate.
Is there a way to check whether it is itemtemplate or edititemtemplate.
I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.
I have a <%Bind("prict")%> and I want to put the word Pri: in front of it but, it even appears if this field is null. How do I do this?
