View 7 RepliesI am writing a programme for Payment calculations.I have four textboxes txtPaymentDue, txtDiscount, txtBalancePaymentDue, txtAmountPaid, txtChange
PaymentDue, BalancePaymentDue and Change are calculated by the programme.My requirements are:
1) when i enter Discount in txtDiscount on EnterKeyPress cursor should go to txtBalancePaymentDue wherein it will display the calculated BalancePaymentDue and on next EnterKeyPress the cursor should go to the txtAmountPaid and finally on EnterKeyPress the cursor should move to txtChange.
2) When I enter a digit in txtDiscount it should take it as right to left sequence and it should allow the insersion of digits .......like if i want to type 36.45 then if i type 5 the texbox should immediately look like this 00.05 when i type next digit it should look like this 00.45 likewise when i type next digit it should display 06.45 and finally 36.45.
i want the user only enter text value in texbox. I use this code to do but it gives me a error.

Is there a way to detect whether text inside a textbox is highlighted from a user using a mouse either by double clicking or click and drag inside a textbox?

Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?

To simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
