Filter records in gallery control based on value selected in other gallery control in PowerApps.

Introduction:

This blog explains how to Filter records in gallery control based on value selected in other gallery control in PowerApps.

Scenario:

1. I am using Dynamics 365 Connection.
2. I have data source named as Time Entry within that data source I have fields named as  Projects  and  Project task and data type of both fields is lookup.
3. Values in Project Task is filtered based on value selected in Project field.

Implementation Steps for Filtering Project Task based on Project:

1. We must add Projects and Project Task data source in PowerApps because their data type is Lookup.(If you don’t know how to work with lookup fields Refer: https://www.cloudfronts.com/connect-dynamics-365-use-lookup-field-dynamics-crm-powerapps/ )
2. Add New screen name it Project Lookup and add gallery control on that screen.
   • Select gallery control and set its item property to:SortByColumns(Search(Filter(Projects,statecode=0 ), TextSearchBox1_1.Text, “cf_name”), “cf_name” )
3. Add new Screen and name it Project Task Lookup and add gallery control on that screen.
   • Select gallery control and set its item property to:SortByColumns(Search(Filter(‘Project Tasks’,     _cf_project_value =Gallery1.Selected.cf_projectid),TextSearchBox1_2.Text,”cf_name”),”cf_name”)here: Gallery1 is the name of gallery control on Project Lookup screen.
