You are looping through the rows. You may know which column to be searched. Then check for the value in that column for each rows. What exactly is the problem

Hi Gowdhami,

In your loop calculating the cf, store the cf as key and row index as value in a dictionary. Later once the random number generated check the dictionary whether the random number matches with any cf..(just use the contains(key) method to match). If the random number exists you will get the row index. Using the result row index you can get the row from the gridview then the desire cell or the value in it.

Does this help?

Note: Random number may not exactly match in the cf collection. Instead you want to find the nearest value?.
