And? What is it doing that it shouldn't, or not doing that it should? Remember that we can't see your screen, access your HDD, or read your mind!

i want to calculate installment record on the basis of if conditions, if value of textbox is 1, loop will calculate the installments of 12 months, if value is 2 it will count installments of 24 months and result will show in gridview.

OK - and what is the problem? Apart from you are duplicating a lot of code there which would be better in a method called in three places with appropriate parameters, what is the problem? Does the code you have work? Not work? Explode? :laugh: I can't see what you are trying to do, so I can't answer!

Change this line
if (txttenure.Text == "1")
to this
if (int.TryParse(txttenure.Text, out b))

its working but it is disturbing my installments amount per month, due to out b
adriancs - 7 Nov '12 - 8:48
If it is disturbing your b, then you can make it out a or out c or out anything you like. By this, it won't affect your b.
1. there might be error in your comparing so use string compare function, to compare values and locations.
2. use a try catch block to see if there is any error, (you are casting a lot of strings to double and float, may be some/any of them not correct order).
 
try this
 

try{
if(string.Compare (txttenure.Text, "1", true)==0)
{
}
}//end of try
catch(Excetion ex)
{ MessageBox.Show(ex.Message); }
