Bind data in datagrid in code behind in WPF

Question

I am having datagrid and data loaded from the SQL. In that datagrid, I m having many colums along with mobile number and checkboxes with select all checkbox. If I click on that select all checkbox, all the mobile numbers should be displayed on another datagrid.

 

Can anyone suggest me solution?

Have you cheked that you get all the values from textbox and dropdown because this error is generate because values are not coming in one of them.
