I have a detail form that get filled in by values from a table adapter. When the "endedit" is called as part of the update routine, one of the fields is changed for no known reason.
How can I find and look at the actual code that "endedit" uses?
Or how can I regenerate the code?
I have a DataGridView that loads an Access database when the application starts. I also have a bunch of text boxes that are bound to the same database. When you click on a row in the DataGridView the text boxes display the data for the record you clicked on.. perfect so far... now when I want to add a new record..
I do...
BindingSource.AddNew()
This removes all the data from the textboxes and I start typing away.
When im done I hit a Save button with the following code.
BindingSource.EndEdit()
It removes all the data from the text boxes but never saves to the database!

View 4 Repliesi have a datagridview bounded to a bindingsource that's pointing to a datatable created at runtime. In the same form i have a Add New, Save and a Cancel Button,the Add new calls the addNew, the Save Calls the EndEdit and the cancel the CancelEdit. Now the problem, if i fill only some fileds in the new row and call the cancel edit, the row is deleted, but if i fill all fields and i call cancel edit nothing happens.What i want it's, when i press the cancel button even if i put values in all fields the row get deleted.

I'm working on a project for school. One part of the assignment is to change the font of the value in a textbox, the font on a label, etc. Which I can do. However, I wanted to add a feature that restores the original values. I was having trouble knowing what to call that or how to access that info.
I'm using the FontDialog box. So I can have the user select a font and change whatever I let them. But I want to have a reset button or something that sets it back the way it was. How do I access that value?

View 1 RepliesThe Textbox_TextChanged event fires when a key is pressed or when text is pasted while cursor is in a text box.
Is there an event that fires on Textbox1.text="NewText"? How do I detect this?My reason for doing this is I would like to reformat text property automatically on assignment rather than do something like textbox.text=myreformat("Newtext").I can put code in validating or validated event but then I'd have to force focus/lostfocus to trigger one of those events.
I'm studying chemistry and wanted to make a quick app for studying the periodic table. What I have is 36 text boxes. I have a structure that can hold each of the 36 element's info, and an array with 36 instances of the structure.
Example:
Dim Elements(37) As Element
Structure Element
Dim strSymbol As String
Dim strElementName As String
Dim strNumber As String

When I mess with it, sometime the text boxes will fill in, but randomly and the comparison between the input text and the info stored in the data structure never compare correctly. 90% of the time the structure data is showing a null.
