Dropdownlist Onchange Action
Jan 24, 2012
In my view there is this DropDownList:
@Html.DropDownList("fOrderstatus", TryCast( ViewBag.StatusOptions, SelectList), "--pick--", New With { .title="Pick an orderstatus"} )
The view shows purchaseorders and the dropdownlist should give the user the possibility to filter, e.g. choosing only 'active' orders.
I prefer a solution in plain vanilla ASP.NET MVC.
In old skool ASP classic I would have an onchange=submit in the SELECT and in the called ASP (via the FORM action) a Request.Form([name of the SELECT])...

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out

I have a DataGridViewComboBox in a dgv and I need to detect when the user changes the value....I thought I could use the CellContentClick; however, it doesn't fire when I select from the dropdown in my dgv so thinking I need a different method to choose from.

I can't quite get a variable to pass between buttons. The variable that I want to pass is totalNumbers and each time a different button is pressed its supposed to subtract a predefined number. Im getting three errors all to do with "Statement cannot appear inside a method body. End of method assumed." What I am trying to do is put a sub procedure inside a button that will be passed back and forth between my call statement and my private sub btnBegin.

I have two datetime pickers that when changed call a function that validates the two dates and changes them as needed. This currently causes a loop where the function changes the dates on the datetime pickers that triggers the function again...
So I would like to disable the datetime pickers valuechagned function while the function runs then re-enable it after it makes the required changes.
Private Sub dtpStartDate_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dtpStartDate.ValueChanged
subValidateDate()

I'm creating a number of textboxes, all calling a function during the onchange event to update their value to the database. These boxes are dynamically created in the backend because the data changes based on specific criteria that can be changed on the page. Here's the creation of the boxes:
Dim t as TableRow
tC = New TableCell
Dim txtBox As New TextBox
[Code]....
When I enter a number into the Textbox, the event fires as expected, but it fires twice.

I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table

This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.

I have searched high and low for documentation on how to use this feature. While the loop I could write would be simple and take no time, I really would like to learn how to use this. Basically I have a class, say, Widget, with a Save() sub that returns nothing. So:
Dim w as New Widget()
w.Save()
basically saves the widget. Now let's say I have a generic collection List(Of Widget) name widgetList(Of Widget) and I want to run a Save() on each item in that list. It says I can do a
widgetList.ForEach([enter Action(Of T) here])
....but how in the F does this work??? There is no documentation anywhere on the intrablags.

I am having trouble doing something that is probably pretty simple!I have a stock listing that is done by 1) a simple form with parameters (Index) and 2) an ajax called partial view that displays the list of stock (based on the params).On this same simple form (Index) I have an action link to an "Add Stock" method which calls another form for adding stock.When the user has finished adding the stock I redirect them back to the stock list page (Index).
My issue is that I would like to "remember" the parameters that were initially entered in this form so the user isn't just directed back to a page with blank parameters forcing them to enter them again.I thought I could simply overload the Index method as such:
[Code]...
I get this error: The current request for action 'Index' on controller type 'StockController' is ambiguous between the following action methods:.Now I have read this post and it's answer but I cannot figure out how to implement the solution. Is this solution applicable in my situation? Is there a better way to acheive what I'm trying to do?
