[sri devi]

Hi Frnz,
Kindly, help me. How to compare a single row with a whole column value in C3
For Ex:
ROW COLUMN
----------------------
SRI DEVI
BABU
SRI

I want to know the first row value "SRI" is present in that column or not. If its present no work, if its not present the row[0] value will be my answer......

 DataTable dt1 = new DataTable();
       
 for (int i = 0; i < dt1.Rows.Count; i++)
        {
            DataRow dr = dt1.Rows[i];
            for (int j = 0; j < dt1.Rows.Count; j++)
            {
                if ((dt1.Rows[i][8].ToString()) != (dt1.Rows[j][12].ToString()))
                {
                    string str2 = ds1.Tables[0].Rows[i][0].ToString();
                    dr["Filter-Link2a"] = str2;
                }
            }
        }

I think you want to check if the value SRI is present in datatable or not.

try something like this

DataTable dt = new DataTable();
        foreach (DataRow dr in dt.Rows)
        {
            if(string.Compare(dr["Columnname"].ToString(),"SRI",true)==0)
               //write your logic
        }

  DataTable dt = new DataTable();
     string link1 = dt.Rows[0]["Link1 "].ToString();
           foreach (DataRow dr in dt.Rows)
            {
                
                if(string.Compare(dr["Link2"].ToString(),link1,true)==0)
                   //write your logic
            }
