Not a question. What's the problem?

I hope your checkbox column isn't the first column of your datagridview, or else your 'string s = row.Cells[0].Value.ToString();' will be either "true" or "false".

Hi,

Parse the string to int.

C#

int numVal = Convert.ToInt32(yourstring);

or

C#

int num = int.Parse(text);

Hope this helps.

If i do that it is giving me error.
Input string is not in correct format.

did you try this way?

string s = row.Cells[0].Value.ToString();
int numVal = Convert.ToInt32(s);

On debug ,check the format of the string that you are getting in 's' variable.If there are any spaces or any others charecters or a null value.If there are spaces, trail off the spaces and convert/parse to int.
