In data table In three rows value given below
 
1 2 3 4 5 6 7 8
9
10 11 12 13 14 15 16 17 18 19 20 21 22
23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44
45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66
 
 
I will check duplicate value occur. like if 2 is occur in two times show the validation message.like Duplicate value occured.
if (ds.Tables[s].Rows[0][i].ToString().Trim() == "")
{
dt.Rows.Add();
dt.Rows[mn][0] = "Tag Number Should Be Mandatory" +ds.Tables[s].TableName; 
}
Above code i will check if the empty filed occur in table show the mandatory message.Now i want to validate duplicate value occur.

  1. <ItemTemplate>  
  2.     <%# Container.DataItem("columnName") == "N" ? "<a href="" />" : "<asp:ImageButton ID='ImageButton1' ImageUrl='<%#Eval("Item")%>' OnClick='ImageButton1_Click' runat='server' />"  %>
