How to use the DataGrid?

Postby fangeles » Thu Mar 07, 2019 4:47 pm


I am using the DataGrid control and having a slowdowns when setting the ItemSource with many records.

Please see my sample code below.

Code: Select all

<DataGrid x:Name="DataGrid1" AutoGenerateColumns="False">
      <DataGridTextColumn Header="Name" Binding="{Binding PersonName}"/>
      <DataGridTextColumn Header="Age" Binding="{Binding PersonAge}"/>
      <DataGridTextColumn Header="Address" Binding="{Binding PersonAddress}"/>
      <DataGridTextColumn Header="Contact Number" Binding="{Binding PersonContactNumber}"/>

Then my C# code.

Code: Select all

public class Person
   public string PersonName { get; set; }
   public int PersonAge{ get; set; }
   public string PersonAddress{ get; set; }
   public string PersonContactNumber{ get; set; }

private void FillDataGrid()
   List<Person> Listing = new List<Person>();
   //This loop adds let say 1000 items to the list
   for(int index = 0; index < 1000; index++)
      Person current = new Person();
      current = GenerateDummyRecord();
   //Sets the Listing as the item source of DataGrid
   DataGrid1.ItemsSource = Listing;

But as what I observed, the rendering of the DataGrid (loading, going to previous or next page of the DataGrid) is slow and will hang the UI.

Am I using the correct method?
Will wait for your feedback.
