Question

When I bind the data collection to my data grid its not show the data instead of data it show the model class name how many row i have that much of time. I tried the normal WPF Data Grid and Dev Express Data Grid both but anything is not working to me.

XAML:

Using WPF DataGrid

 <DataGrid ItemsSource="{Binding EmpDetails}" AutoGenerateColumns="True"/>

Using Dev Express DataGrid

 <dxg:GridControl ItemsSource="{Binding EmpDetails}" AutoPopulateColumns="True" AutoGenerateColumns="AddNew" >
                            <dxg:GridControl.View>
                                <dxg:TableView />
                            </dxg:GridControl.View>
                        </dxg:GridControl>

Thanks for your spending time to my question.

Answer 1

Put the EmployeeDetails is Observable Collection and All the Columns of the table write as the Property with OnPropertyChange include the Model Class.

EX:

private string firstName;
public string FirstName
{
 get {return firstName;}
 set { firstName = value; OnPropertyChange("FirstName");}
}
