Hi all

I am binding data in a data table where i am getting entries 3 times for same row.

below is the code

C#

if (ls_SRDF_Status != "")
 {
     ls_DRName = ls_DRName.Replace("_clone_file", "");
     if (intchck_1 == 1)
       {                                                                 Obj_DT_SRDF.Rows.Add(ls_IP, ls_SerialNumber, ls_DRName, ls_SRDF_Status, ls_Clone_Status, ls_Time);
       }
     else
       {                                                                       Obj_DT_SRDF.Rows.Add(" ", " ", ls_DRName, ls_SRDF_Status, ls_Clone_Status, ls_Time);
       }
 }

Here i want to check wach time that if "ls_DRName" is already there in data table then don't add that row.

Please tell me how to do this.

Hi,

you can do a search operation with the datatable and get to know whether there is an entry for the particular value or not. For checking that you can follow following code:

SQL

DataRow[] found = Obj_DT_SRDF.Select("ls_DRName = '" + ls_DRName + "'");
if(found.Length == 0)
{
    // Insert the record or else don't insert
}

Hope this will help you out in checking the duplicate values and preventing the insertion of the duplicate values.

Thanks,
Sisir patro
