View 3 RepliesI'm used to webdeveloping, and when I work with databases, I usually use some text for the Text-property of a radio button, and the row's ID as Value-property. This makes it very easy to save to databases.
Is the an equivalent in winforms for the Value-property, or will I have to identify rows based on the text in the control?

In WinForms I could handle the Validated event to do something after the user changed text in a TextBox. Unlike TextChanged, Validated didn't fire for every character change; it only fired when the user was done.Is there anything in WPF I can use to get the same result, an event raised only after the user is done changing the text?

100

View 1 RepliesI want my code to look at a textbox to determine which letter is in it, & assign a numerical value to a second textbox, based on what letter is in the first textbox.[code]The problem is that, when I step through the code, I can see that Form20.txtGrade1.text DOES EQUAL "C", but my code skips over the part that says Form20.txtGrade1a.text = "4". Instead, if I hover over that part, I can read Form20.txtGrade1a.text = " ".When I do not step through the code, and just run it, I see the two textboxes, with the first one containing the C, and the second one is just blank.
View 4 RepliesI've made a temp converter and i'm looking to get some validation for it. I have looked online, but most do it in a way that i don't want.
I have 3 text box's, of which i only want numerical values and nothing else to be entered into the boxes. However, i would like the validation to run when a button is pressed (in this case, the calcualtion button). I would like a messagebox to pop up stating there is a non-numerical value entered into any of the boxes and for the calculation code to not run.
I have code that will validate whether or not the input is numerical. After that's passed validation, I need to check and see if that value is greater than another.
Here's the code for the numerical validation (it works)
If Decimal.TryParse(EndOdometerTextBox.Text, EndOdometerDecimal) Then
ErrorProvider1.Clear()
Else
ErrorProvider1.SetError(EndOdometerTextBox, _
"Please enter a numeric value.")
EndOdometerTextBox.SelectAll()
e.Cancel = True
Now, I need to verify that the input for this is greater than another decimal (BeginOdometerDecimal). How can I do this? Everything I've tried fails completely (ignored) or messes up the fist validation.
I'm trying to write a Database manager in VB (2010) that updates a SQL database that compiles and summarizes my financial records. The code works, but I'm having issues with one exception that I think I understand, but can't circumvent. I've built an I/O form that enters a series of purchases and sales into a temporary datatable. After review of the list, the program connects to the database and executes the SQL. That all works and isn't a problem.
