There are many ways to achieve similar effects. The most basic thing is to add a sort description for the listview collectionview In the Click Event of the gridviewcolumnheader control. There are also some more perfect ones, such as adding up and down arrows on the column buttons through the modifier (adorner) to indicate the sorting direction, so I will not repeat others hereCodeIf you are interested, you can read this article.

 

This method is simple and easy to use. For example, the data class is "person", which has the name, age, and score attributes representing the name, age, and score. On the listview, the name and age are displayed directly, and the score value is displayed in a progressbar using a data template. Finally, you need to sort the values after clicking. The effect is shown above.

 

In XAML, the implementation is very simple:

<! -- First set sortedenable = "true" -->

<ListviewName="List"Loc:Listviewhelper. sortenabled="True">

<Listview. View>

<Gridview>

<GridviewcolumnHeader="Name"

Width="120"

Loc:Listviewhelper. sortproperty="Name"/>

<! -- No sortdirection is set. The default sorting direction is ascending. -->

<GridviewcolumnHeader="Age"

Width="50"

Loc:Listviewhelper. sortproperty="# Age"/>

<! -- Add # Before the attribute name to set the initial sorting direction to descending -->

<GridviewcolumnHeader="Score"

Width="100"

Celltemplate= "{StaticresourceDatatemplate}"

Loc:Listviewhelper. sortproperty="Score">

<! -- Set the template. Note that the celltemplate is set before sortproperty. -->

<! -- If it is placed after, sortproperty finds that the celltemplate is not set at the time of setting, so that displaymemberbinding is automatically set -->

<! -- Once displaymemberbinding is set, celltemplate automatically becomes invalid -->

</Gridviewcolumn>

</Gridview>

</Listview. View>

</Listview>

 

OK. In fact, the sorting function is based on two additional attributes of the listviewhelper class.

The sortenabled attribute is applied to the listview to process the click routing event of gridviewcolumnheader on the listview. Therefore, the entire sorting logic can be correctly performed only when sortenabled is set to true.

The sortproperty attribute is applied to the gridviewcolumn in the listview. Interestingly, if the celltemplate and displaymemberbinding of the gridviewcolumn are not set, the sortproperty will automatically set its own value (that is, the attribute value of Data Object sorting) automatically Set to the path value of displaymemberbinding of gridviewcolumn. In additionThe celltemplate must be defined before sortproperty; otherwise, the sortproperty will first set displaymemberbinding and invalidate the celltemplate.. Finally, adding # Before the attribute name indicates that after the column is clicked for the first time, the column will be sorted in reverse order. Otherwise, the column will be sorted in ascending order by default.

 

Note:

After 5.0, when the data source type is listcollectionview,ProgramThe delegate generated by the expression tree is used to speed up sorting.

After 7.0, the attribute name can be a null string that indicates sorting the current object (rather than its attribute value ).

Version 4 (2012-6-10)

> Fixed the exception thrown when itemsource is null.

> Remove the sortdirection additional attribute. You can add # Before sortproperty to set the sorting order. This makes it easier to use and avoids the impact of the additional attribute setting sequence on the default value setting.
