SharePoint
web parts and app parts are very useful, and if you have
followed this series you have already learned how to use
several different kinds of web parts. Here we will look
at how web parts can be connected.
Note a list web part or app part cannot be connected to
another web part if the default view of the list is the
Datasheet/Quick Edit mode. It has to be the Standard view.
In the demo below Peter Kalmström, CEO and Systems Designer
of kalmstrom.com Business Solutions, uses a Customers list
where country is one of the metadata. He adds it in a web
part on a page where he also adds a Choice Filter web part.
In the Choice Filter web part Peter can add the same country
alternatives as in the Customers list. Therefore, when he
connects the two web parts users can select a country in
one web part and see all customers in that country displayed
in the other web part.
Connect web parts to show filter choices by selection
Click on the settings gear and select 'Add a page'.
Give the page a name and click on Create. The new
page opens in Edit mode.
Place the mouse cursor where you want the Customers
list to be displayed and click on the Web Part button
under the INSERT tab.
Select the Customers list and click on Add.
Place the mouse cursor where you want the Choice
Filter web part to be displayed and click on the Web
Part button under the INSERT tab.
Select the Choice Filter web part in the Filters
category and click on Add.
In the Choice Filter web part, either click on the
Web Part Properties button under the WEB PART tab or
expand the accordion in the top right corner of the
web part and select 'Edit Web Part'.
Enter your choice alternatives in the right panel.
Expand the accordion in the top right corner of
the Choice Filter web part and select Connections >Send
Filter Values To >Customers.
In the pop-up window, select to get filter values
from Country.
Click on Finish and save the page.
It is sometimes difficult to get web parts on the right
place, but you can minimize them and drag and drop them
to the positions you prefer. Peter shows how to do that
in the demo.
Peter also shows a quick way to get the filter values. As
he has the same options in the Customers list, he can edit
the column, copy the alternatives from the Choice field
and paste them into the Choice Filter web part.
In the two following articles we will show other ways to
filter customers by country.
