i was trying Flight Ticket Booking System in VB.NET 2015 with Msaccess 2010. I had Qty textbox. If Qty was 3 then, i need to split the Qty like males Qty, Females Qty, Children Qty in Numericupdown Tool. Eg., If Qty (Text Box value) like 3, then i was split the Value male 2 (Numericupdown1 value) and then Female 1 (Numericupdown2 value). Then automatically, numericupdown should be disabled. When i change the Qty, then Numericupdown values are Enable.

You have the logic in your question. You just need to add the code to enable or disable the various controls based on those conditions.

Solution 1

Use something like:

Dim amount As Integer

If Integer.TryParse(qtyTextBox.Text, amount) Then
   Numericupdown1.Enabled = (amount <= 3)
End If

Thanks for your reply. I had more than one Numericupdown Tool. 3 is just an example. I need runtime value changing. when my Qty criteria meet the numericupdown1, all numericupdowns are change to disable mode.If numericupdown1 & numericupdown2 adding value should meet my Qty criteria, all numericupdowns are change to disable mode. Please help me.

Solution 2

Too slow (up and down) in this case; use (3) banks of radio buttons.

And adults and children make more sense than male, female, children (unless we're talking segregation).

And if it's a "party of 5 with 1 adult" than you can "compute" the rest.
