data binding - How to make a WPF ComboBox editable with custom values -


I have to put a combo box which allows selection from the list of values ​​and also the custom value typed in the text Allows Items are a complex type for the reasons shown (CongoBox shows a patch of item template color and shows that it is a custom color). 

  Public Class ColorLevel {Receives {Public Decimal Intensity}; Set; } Public bool isCustom {get; Set; } Public color basalole {get; Set; } Public override toasting () {Return string. Format ("{0}", Intensity * 100); }}

example item 

  var items = new [] {new ColorLevel {Intensity = 0.9m, IsCustom = false, BaseColor = Color.Red} , New color level {intensity = 0.7m, icicute = false, basecolor = color Rd}}

xml 

  & lt; Combo box selectedItom = "{binding path = selected collar level}" isadetibil = "true" isTextSearchEnabled = "true" & gt; & Lt; / ComboBox & gt;

The above markup works when an item item is selected from the list. And as you type with text search, the matching item is selected if the typed text does not match any object, then the selected coler level is set to clear.

At which point the question is (and how) it is best to create a new custom item that can be set to the selected caller level, when typed text does not match any item. For example, I would like to assign a new item to the value selected as 

  New ColorLevel {Intensity =

or text using text controller You can use the database for the property.

Not sure I fully understood .. You can use the event, for example, when the return is pressed if the item is an observable collection and you set it as the item source of the combo box, then the new ColorLevel to be added to the item will be available in the list. Should and must be selected event.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
