Solving Datacontext Inheritance Issues In Wpf Contentpresenter For Custom Tabcontrols

Contentcontrol Does Not Display Content Of A Datatemplate Issue 9190 The list of tabitems that are assigned to the items collection in xaml do not seem to build a visual or logical element tree, so that there is no value inheritance of the datacontext property across this boundary. try to derive your custom tabcontrol from itemscontrol or selector. Discover solutions to fix the `datacontext` inheritance issue while building custom tabcontrols using wpf's contentpresenter. more.

C Wpf Customcontrol Templates Inheritance And Dependencyproperties the default contentsource is "content". that means it'll look at the content property of the templated parent and it'll take whatever it finds there for its own content. Control.datacontext is wrong no matter what specific control is used. contentpresenter supposed to be used as a root element of a contentcontrol's control template (not data template). you aren't supposed to use it directly. use contentcontrol instead. The auto generated contentpresenter sets its datacontext from the content of its templated parent (which is null as shown in your screenshot). you have to set the content property of m pageviewmodelcontrol to the desired data so it is inherited down the tree of the contentpresenter:. The intended usage of contentpresenter is to set the content to some binding to a data object, then control the element tree via the contenttemplate property. that may lead to a counterintuitive situation when you want to specify some ui element content and then use bindings in that content.

C Wpf Xaml Mvvm Inheritance With Multiple Contentpresenter Stack The auto generated contentpresenter sets its datacontext from the content of its templated parent (which is null as shown in your screenshot). you have to set the content property of m pageviewmodelcontrol to the desired data so it is inherited down the tree of the contentpresenter:. The intended usage of contentpresenter is to set the content to some binding to a data object, then control the element tree via the contenttemplate property. that may lead to a counterintuitive situation when you want to specify some ui element content and then use bindings in that content. A contentpresenter can use a logic class to influence which template to use for templated data content at run time. for more info, see the contenttemplateselector property. Explore common wpf datacontext binding problems within usercontrols and learn effective solutions using relativesource and elementname bindings. While there are frameworks to help you define your datacontext in a more flexible way (e.g. mvvm light has a viewmodel locator that uses inversion of control), we use the quick and dirty method for the purposes of this tutorial. you can define a datacontext for pretty much any visual element in wpf.
