    <asp:Button ID="Submit" runat="server" />
    
<div style="font-size:14px; color:Navy">
     </div>
</div>

My code as follows

protected void Page_Load(object sender, EventArgs e)
{
    SqlConnection con = new SqlConnection("Server=(local);initial catalog=Himt_Testing;Trusted_Connection=True");
    string str;
    SqlCommand cmd = new SqlCommand("select *  from Tb_Course_details", con);
    cmd.Connection.Open();
    Repeater1.DataSource = cmd.ExecuteReader();
    Repeater1.DataBind();
    cmd.Connection.Close();
}

when i run the above code shows output as follows in repeater control

Coursename   Amount   Coursedate

RPST       400       29 Apr 14
RPSCRB     500       30 Apr 14

Then i have one button called Submit.

When i click submit button,i have to show the message the RPST and RPSCRB course must be same date.

for that how can i validate using repeater control.
