1. Catch the SqlException object
2. Check if the error is deadlock error using the Number property of the SqlException object

Begin Tran
Update TableA Set Name = 'Mark Transaction 1' where Id = 1
Waitfor delay ' 00:00:05'
Update TableB Set Name = 'Mary Transaction 1' where Id = 1
Commit Transaction
End

Stored Procedure 2 Code

as
Begin

End

WebForm1.aspx.cs code

namespace Demo
{ public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) {} protected void Button1_Click(object sender, EventArgs e) { try { string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString; using (SqlConnection con = new SqlConnection(cs)) { SqlCommand cmd = new SqlCommand("spTransaction1", con); cmd.CommandType = CommandType.StoredProcedure; con.Open(); cmd.ExecuteNonQuery(); Label1.Text = "Transaction successful"; Label1.ForeColor = System.Drawing.Color.Green; } } catch (SqlException ex) { if (ex.Number == 1205) { Label1.Text = "Deadlock. Please retry"; } else { Label1.Text = ex.Message; } Label1.ForeColor = System.Drawing.Color.Red; } } }
}

WebForm2.aspx.cs code
namespace Demo
{ public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) {} protected void Button1_Click(object sender, EventArgs e) { try { string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString; using (SqlConnection con = new SqlConnection(cs)) { SqlCommand cmd = new SqlCommand("spTransaction2", con); cmd.CommandType = CommandType.StoredProcedure; con.Open(); cmd.ExecuteNonQuery(); Label1.Text = "Transaction successful"; Label1.ForeColor = System.Drawing.Color.Green; } } catch (SqlException ex) { if (ex.Number == 1205) { Label1.Text = "Deadlock. Please retry"; } else { Label1.Text = ex.Message; } Label1.ForeColor = System.Drawing.Color.Red; } } }
