Always use pre tags for code for better readability.

It isn't too clear from your question what problem you are having - I assume that English is not your native language? So, I will have to make some assumptions:
1) You have a GridView, which displays two or more columns.
2) One of these is a Checkbox, called "CheckBox1", and the user (or your code) checks some CheckBoxes, and not others.
3) If a CheckBox is checked, include the value of the Rate column (Column 1, or the second column in the GridView) in a running total.

If this is correct, then:

// Select the checkboxes from the GridView control
int totalRate = 0;
for (int i = 0; i < GridView2.Rows.Count; i++)
{
    GridViewRow row = GridView2.Rows[i];
    bool isChecked = ((CheckBox)row.FindControl("CheckBox1")).Checked;
    if (isChecked)
    {
        // Column 1 is the "Rate" column of price
        totalRate += int.Parse(GridView2.Rows[i].Cells[1].Text);
    }
}
// prints out the result
Response.Write(totalRate.ToString());

You may need to change the int to another data type - if so do not forget to change in in both places!

If this is not correct, then what are you trying to do?
