By default, the ComboBox in winform is set to display the list in multiple texts, which is usually not in line with your daily applications,
Because daily applications usually bind key-value pairs.
So what should we do in the form of key-value pairs?
Because the value of each item in combox is an object, it is actually a key/value pair.I use an instance of the following class as an item:
/// /// ComboBox item/// Class listitem: system. Object{Private string _ value = string. empty;P
The first method is relatively cumbersome, and the second method is relatively simple. The first method is as follows: 1. first, the repeated items in the string are merged to obtain the repeated item names and repeated times in the form of objects; 2. root... the first method is cumbersome, and the second method is simple.
First:
Basic Ideas:
1. Merge repeated items in the string to get the repeated item
Solve the problem that the items on the statusStrip control cannot be right aligned.
The status bar control StatusStrip is used in c #, but an error occurs when I want to align a StatusLabel on StatusStrip to the right.
In MSDN, set the Alignment attribute of ToolStripStatusLabel to Right. However, I cannot find Alignment in the design attribute window.
Even if you add toolStripStatusLabel2.Alignment = ToolStripItemAlignment. Right;, it still has no e
In this paper, the use of the Dictionary items () series functions in Python is described, which has a good reference value for Python program design. The specific analysis is as follows:
Let's look at an example first:
Import HTML # available only in Python 3.x def make_elements (name, Value, **attrs): keyvals = ['%s= '%s '% item F or item in Attrs.items ()] attr_str = '. Join (keyvals) element = ' '. Format ( name = name, attrs

The business scenario is this: there is a query dictionary table in the project that returns the IEnumerable, bound to the foreground DropDownList. Need to add "= = Please select =" in SelectList first item.Online search, there are about 7 ways:1It's really not necessary unless you stick to the value of 0 to do it. The extension of the HtmlHelper DropDownList allows you to set an option label that shows the initial value in selecting a null value. A DropDownList signature with the option label.
Today, when rewriting the sorting Operation Method in the background management, I wrote a script program that runs on the client to change the order of items in the ListBox control, now, I want to help JavaScript beginners. Of course, we also recommend that you do not joke about JavaScript.
Note the following before you post the Code:
Normally, when you use this function, it is meaningless to adjust the order of

Step one: Select Show > Show duplicates to display duplicate items (match by song name and performer). If the same song has multiple versions (such as Live and studio editions, or versions from different albums), you can hold down the ALT or Option key (applicable to Mac OS X) or Shift (for Windows), and then choose Show > Show full duplicates. This will only show repeated songs with the same name, performer, and album.
