I have updatePanel and hiddenField in it. I need to save object to hiddenField without full pastback (only updatePanel updating).ViewState can't help, because it works only with full postback.

View 4 RepliesI have a page like Order - Order lines. Order represents by some textboxes and ddls, Order lines represents by GridView.
I want to let users add order lines without save changes to database. For example: he adds 4 order lines, fill order info and then hits Save button. Only an that moment all information should be saved to DB.
When I use code like
using (Entities ctx = new Entities())
{
//create new OrderLine
OrderLine ol = OrderLine.CreateOrderLine(1, 1, "", 1);
//add OrderLine to OrderLines collection
ctx.CreateOrderLines.AddObject(ol);
}
newly created OrderLine does not appears in my object context, so I can't access it and bind GridView to new OrderList collection.
How can I solve this problem? Or maybe there are another ways to perform this task?
I have a form where users upload a file (csv), then the server does some processing, and generates a datatable. the table will be shown in grid. however, the table's column is unknown, and sometimes, the table is huge. I need show this table in another form.
It seems session variable is not good for this since the table maybe huge. is there a way to write this table to sql, then load it again in the other form?
I have a table into the database. Table name is NewResults. I have created instance of NewResult called result and fill it with all the infos i need. Now when I try to add i dont have add method in
context.NewResults. -> no Add here. So if i enter context.NewResults.Add(result) error as below is shown:
Error 1 'System.Data.Linq.Table<UDWAutoLinqTry.LinqToSql.NewResult>' does not contain a definition for 'Add' and no extension method 'Add' accepting a first argument of type 'System.Data.Linq.Table<UDWAutoLinqTry.LinqToSql.NewResult>' could be found

what am i missing?
I know that i dont have to create add method myself i was googling and i am doing everything as it should but still no luck?
I am trying hard to update a business object inside a List<>.
I am using a checkbox list
When a checkbox list item is clicked I check if it exists, if yes I mark it as Dirty (means the user unchecks an item)If not, I add a new item to the list (means the user clicks a new item)and store it in view state
How do I update the Generic List with the Dirty Object ?
On form update, do I foreach and make separate lists of dirty and new objects to send to DB layer or would you recommend any other way ?
Here is my code.
protected void cblExclusions_SelectedIndexChanged(object sender, EventArgs e)
{
if (cblExclusions.SelectedIndex != -1)
{
ftExclusions myExclusion=new ftExclusions(); // Business object

I have a for which is built within an ASP.net usercontrol. This form is then used within a CMS as part of integration with a merchant gateway. The gateway requires that a number of hiddenfields be passed in which is fine in the main however one of these needs to be called Profile. The CMS I am using also defines a global variable called Profile and as such when I try and add a hidden field with this ID I get errors.
Is there a way of setting the 'name' property to Profile, and the ID to something different?

<%= Html.Hidden("ContentItem.ContentType.ContentTypeId", item.ContentType.ContentTypeId)%>

I'm making a GridView with like 12 fields and about 8 of them are hidden. I want to display those 8 as details of each row when I select the row with a button. I already have the jQuery function that someone in this forum gave me a couple weeks ago, it is working perfectly fine. The problem I have is that I don't get the value of the BoundField that is visible =False I just get the closest BoundField value of the index that I request (the next of the hidden one). I have used a TemplateField with a HiddenField and I have the same problem. There is some way to get those HiddenField? This is the code that I'm using:
