WPF: use additional attributes to record ListBox/listview selection information

You can use this type of additional property to quickly record the selection information of ListBox/listview on the interface.

This type is called listcounter and has three additional attributes:

ListBox: Specifies the target ListBox or listview.

Property: string type, which specifies the attributes of the current object to be set.

Formatstring: string type. Optional (because of the default value). The format string is specified. {0} indicates the number of all elements, and {1} indicates the number of selected elements.

 

It is easy to use, for example:

<ListBox name = "lbx" selectionmode = "extended"/>

<Textblock LOC: listcounter. ListBox = "{binding elementname = lbx }"

Loc: listcounter. Property = "text"/>

 

Result:

 

The text attribute of textblock is set to the selection information of ListBox.

Of course, you can add custom format strings or set other attributes:

<ListBox name = "lbx" selectionmode = "extended"/>

<! -- Set the content of the button -->

<Button name = "TBL"

Loc: listcounter. formatstring = "{}{ 1}/{0 }"

Loc: listcounter. ListBox = "{binding elementname = lbx }"

Loc: listcounter. Property = "content"/>
