WPF Listbox Binding from MS SQL Database 02

WPF Listbox Binding from MS SQL Database

Let’s see how we can Bind WPF Listbox from MS SQL Database.

WPF Listbox can be filled from database using IList which contains items fetch from Database. In the below WPF example I will be binding it using IList and MS SQL Database.

My Database table : tblCountries

WPF Listbox Binding from MS SQL Database 01

Code :

 

WPF Listbox Binding from MS SQL Database. Make a WPF Listbox in your WPF Form as below :

<ListBox Name="lstBox" HorizontalAlignment="Left" VerticalAlignment="Center"
Background="#fff" >
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left" >
<TextBlock Text="{Binding id}" Margin="2" FontWeight="Bold"/>
<TextBlock Text="{Binding country}" Margin="2" />
<TextBlock Text="{Binding ondate}" Margin="2"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

Open your code page (.cs page) and write the below code to fill WPF Listbox from MS SQL Database.

public void FillList()
{
try
{
con = new SqlConnection(connectionString);
con.Open();
cmd = new SqlCommand("select * from tblCountries", con);
adapter = new SqlDataAdapter(cmd);
ds = new DataSet();
adapter.Fill(ds, "tblCountries");
Countries co = new Countries();
IList<Countries> co1 = new List<Countries>();

foreach (DataRow dr in ds.Tables[0].Rows)
{
co1.Add(new Countries
{
id = Convert.ToInt32(dr[0].ToString()),
country = dr[1].ToString(),
ondate = Convert.ToDateTime(dr[2].ToString())
});
}
lstBox.ItemsSource = co1;
}
catch (Exception ex)
{

}
finally
{
ds = null;
adapter.Dispose();
con.Close();
con.Dispose();
}
}

This will Bind our WPF Listbox from MS SQL Database server table :
