.net - Silverlight Datacontext, Repeats All The Past Commands/action Each Time A New Action Is Performed On It
Mar 28, 2011a 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
UnDo/ReDo Function For .net?
Jul 29, 2009I understand that implementing an UnDo/ReDo function can be complex using Stack operation/XML serialization.
That is why I have started to search for commercial tools/components, but I could find such tools only for RealBasic, not for VB.net. Does anyone know where to get such tool/component, or has good example code to include various undoable operation into an Undo/Redo function, that means undo operation for datagrid and chart manipulation (similar to a spreadsheet application).

Setup Undo / Redo For Changes To A Datagridview
Aug 18, 2009I'm trying to setup undo/redo for changes to a datagridview, but am having a problem with capturing the cell value before it is changed. I am currently using the CellEnter event to capture the original value, which is fine if only one cell is affected. However, if the user selects multiple cells and goes to cut the data (Ctrl-X), CellEnter does not fire for each of the selected sells, only the ones moused over it seems. Is there a better way to capture each cell value before their CellValueChanged event fires?

Increase RichTextBox Undo / Redo Limit
Apr 30, 2012I was wondering if there is a way to modify the limit on the number of undo/redo actions a RichTextBox is capable of performing. It seems as though the limit is around 100, and I really need to increase this because of the demands of my application. I have text formatting (Bold, Underline, etc.) in my application, and since you can change the font of the text, I need to loop through the characters in the SelectedText one-by-one and apply the correct formatting to them in order to prevent any errors from appearing. Every time a single character is formatted, it counts as an action. As you can imagine, this quickly adds up and therefore makes my undo/redo features not as useful as I'd hope with the 100-action limit. Does anyone have any suggestions for me?

View 2 RepliesVS 2008 : Infinite Undo/redo: How To Implement It
Apr 4, 2011basically add and remove text and selection information from a stack. Result: When using Undo/Redo the selection got messed up, the text moved, sometimes causing lag of epic proportions. I need a way of having complete and smooth undo/redo class for storing all information I would possible need.How to know whether or not to add an undo stack is easy, I just checked if the user clicked in the text or moved using the arrow keys. As soon a previous marking was given for "next text change needs to be backed up", it was backed up. At that point I stored the RTF and selection start/length. What do I have to store of a RichTextbox control to be able to restore it to a previous state, and how can I reset it back to a previous state? See it as having a "RichTextBoxState" class:
Public Class RichTextBoxState
Sub New(ByVal RTB As RichTextBox)
Me.text = RTB.RTF
Me.selectionstart = RTB.SelectionStart
[code]....
After restoring it must display the EXACT same thing as when it was saved as a state.

Cancel An ASP.NET MVC Action?
May 12, 2009This 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.

View 1 Replies.net - Action(Of T) In VB In List(Of T).ForEach?
May 21, 2009I 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.
.net - Ambiguous Action Methods - ASP.net MVC?
Jul 16, 2009I 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?
