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.
