How to reset the minsupp..?

Question

how to reset the minimum support that the user enter in the RTB? when user want to change the minimum support they can straight away change from the minimum support RTB and the program can detect and change also.. ?? here is my coding: MinSupp.Clear(); double minsupp = Double.Parse(MinSupp.Text); double totalsupp = 0.0; foreach (var r in p) { totalsupp += (double)dict1[r]; } SingleItemValue.Clear(); foreach (var h in p) { double supp = (double)dict1[h]; double perc = supp / totalsupp * 100.00; if (perc >= minsupp) { SingleItemValue.AppendText(h + : + dict1[h] + 
); hs1.Add(h); } }

If you click on the MinSupp RTB whilst in design mode and then click on the 'lightning bolt' symbol in the Properties Box it will list the events that are applicable. If you then double-click on the Leave Event it will open up a skeleton eventhandler which should look like this: private void MinSupp_Leave(object sender System.EventArgs e) { }

where to do this add the skeleton eventhandler for the Leave event from the VS Properties Box (double click on the name of the event)???

The code will be something like this. It's important to add the skeleton eventhandler for the Leave event from the VS Properties Box (double click on the name of the event) to ensure it's wired up properly: private void MinSupp_Leave(object sender System.EventArgs e) { double temp = Double.Parse(MinSupp.Text); if (temp != minsupp) { minsupp = temp; SomeMethod(); } } private double minsupp; // now a field rather than a local variable private void SomeMethod() { //... MinSupp.Clear(); /* double minsupp = Double.Parse(MinSupp.Text); // remove this line */ double totalsupp = 0.0; foreach (var r in p) { totalsupp += (double)dict1[r]; } SingleItemValue.Clear(); foreach (var h in p) { double supp = (double)dict1[h]; double perc = supp / totalsupp * 100.00; if (perc >= minsupp) // now using the minsupp field { SingleItemValue.AppendText(h + : + dict1[h] + 
); hs1.Add(h); } } // ... }

I suggest you do two things :- 1. Declare 'minsupp' as a private form level variable rather than as a local variable so it will be accessible throughout the form class. 2. Add an eventhandler for the RTB's Leave event from the VS designer. In the eventhandler you'll need to parse the RTB's Text property to a double and if it's different to what it was before change the private field to the new value and call the method which does the appropriate calculations for minimum support.
