Hi all!

I have a crystal report that displays data from datatable as its data source.
One of these columns in the datatable may contain Zero value.
I want to check to that value; if it is Zero, Delete that row for datatable and crystal report.

I have tried this , but still Zeros appear:

C#

for(int m=0; m < mona.Rows.Count ; m++)
       {
       foreach(DataRow data in mona.Rows)
       {
          double Balance = double.Parse(data["Balance"].ToString());
          if (Balance == 0)
          {
              //data.Delete();
              dDebt.Rows[m].Delete();
          }
          else if (Balance > 0)
          {
              dCred.Rows[m].Delete();
          //  dDebt = AddedNewColumnDebt(mona);
          }
      }
       }

Any help, please.

Thanks

Why don't you filter it at database level itself?

Try this one.

C#

DataTable updatedDataTable = new DataTable();
for (int m = 0; m < mona.Rows.Count; m++) {
        foreach (DataRow data in mona.Rows) {
            double Balance = double.Parse(data["Balance"].ToString());
            if (Balance > 0) {
                updatedDataTable.Rows.Add(data);
            }
        }
}

use updatedDataTable as your new DataTable to display the filtered rows.

Solution 2

Change this

dDebt.Rows[m].Delete();

to

dDebt.Rows.RemoveAt(m);
