Hi guys

I have the code below that runs on page load

C#

if (IsPostBack)
               {
                   if (System.Windows.Forms.MessageBox.Show("Sure want to Cancel Appointment?", "Cancel Appointment",
                              System.Windows.Forms.MessageBoxButtons.YesNo, System.Windows.Forms.MessageBoxIcon.Question) == DialogResult.Yes)
                   {
                       systemBusinessLayer = new BusinessLayer();
                       systemBusinessLayer.cancelAppointmentByEmployee(Convert.ToInt32(SlotId), Convert.ToInt32(EmpRecNr));

                   }

               }

Now I have a gridview to cancel an appointment, but it works only if I have "if(!Page.IsPostBack)"

C#

if (!IsPostBack)
               {
                   if (System.Windows.Forms.MessageBox.Show("Sure want to Cancel Appointment?", "Cancel Appointment",
                              System.Windows.Forms.MessageBoxButtons.YesNo, System.Windows.Forms.MessageBoxIcon.Question) == DialogResult.Yes)
                   {
                       systemBusinessLayer = new BusinessLayer();
                       systemBusinessLayer.cancelAppointmentByEmployee(Convert.ToInt32(SlotId), Convert.ToInt32(EmpRecNr));

                   }

               }

Is there another way to run the code on top on page load with out executing it?

Why are you using these many 'i' for i and so many dots. Please avoid it.

You dont want to write it in Page_load. You Can use RowCommand event of Gridview.

For Example Cancel Button in ASPX inside Grid

C#

<asp:imagebutton id="CancelButton" runat="server" imageurl="~/images/CancelButton.jpg" commandname="Cancel" xmlns:asp="#unknown" />

C# Code

C#

protected void MainGridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
   if (e.CommandName == "Cancel")
   {
     if (System.Windows.Forms.MessageBox.Show("Sure want to Cancel Appointment?", "Cancel Appointment",
                              System.Windows.Forms.MessageBoxButtons.YesNo, System.Windows.Forms.MessageBoxIcon.Question) == DialogResult.Yes)
                   {
                       systemBusinessLayer = new BusinessLayer();
                       systemBusinessLayer.cancelAppointmentByEmployee(Convert.ToInt32(SlotId), Convert.ToInt32(EmpRecNr));
   }
     
   }
}
