...I rag on the .NET framework. Here's two lovely examples. The DateTimePicker. Utterly useless as a control that's bound to a nullable field. Utterly useless for creating a "between" query that just needs the dates because when it's converted to a string, it includes the time component unless you do special stuff, even after setting the control to just providing a date picker. Workaround: a new nullable property:
public object NullableValue
{
get
{
// We just want the date with basically a default (but constant) value for the time.
// Get the short date string, as we don't want any time component,
// which hoses up SQL Server's "between" clause if there's a time component.
return Value.ToShortDateString();
}
set
{
if ( (value == null) || (value==DBNull.Value) )
{
Value = DateTime.Now;
}
else
{
Value = Convert.ToDateTime(value);
}
}
}The DataGridView. Select a row and delete it. OK, the "selection list" selects the next available row. Unless you delete the last row. Then the selection list Clears even though the current position has updated to the now last row. Workaround? This inane code to reset to binding source position which forces the selection list on the DataGridView:
protected void OnDeleteRow(object sender, EventArgs e)
{
IXDataGrid grid = (IXDataGrid)IXControl.GetControlByName(dataGridName, (IXForm)
IXControl.FindForm(this));
BindingSource bs = (BindingSource)grid.DataSource;
bs.RemoveCurrent();
UpdateButtonState(grid);if ( (grid.SelectedRows.Count == 0) && (bs.Count != 0) ) { bs.Position = 0; bs.Position = bs.Count - 1; }}
In both cases (well, if I can find the solution to the grid problem), not a total rewrite of these controls, but requiring a derived control to work around the bugs. Oh, excuse me. Features. And this was not a programming question in the lounge. Talk to the hand. :| Marc

Why not develop your own implementations and share them?
The Digital World. It is an amazing place in which we primitive humans interact. Our flesh made this synthetic machine. You see, we are so smart, we know a lot of stuff. We were grown from cells that came from the universe, which the matter and physics I'm typing in it is amazing how the universe is working. Human life is very amazing. How I experience this sh*t its like wow.

Touche. In other words, it's reasonable to assume that Microsoft puts out junk for its .NET control library. Hmmm. Now exactly why shouldn't that reasoning be extended to other aspects of the framework then? Like WPF? Like communications? Hmmm? Marc

No, you're right, the built in controls should be much better. I never was able to figure out if they were rushed out at the last minute or Microsoft really expected 3rd party developers to take up the slack on that all along. Probably a bit of both. I don't know though why they bother doing anything half way, seems like a criminal waste of effort.

:shrug: Frameworks uh, work, when you're writing the application the framework designer had in mind. When you step outside of that, you need to bite the bullet and write your own code. IMHO, the problem with the .NET BCL is that it tries to straddle that line between a set of complimentary, general-purpose libraries (to make writing supporting code for an application easier and more reliable) and a specialized, targeted framework (to make writing applications easier and more reliable). The goals of the latter often appear to be at odds with those of the former. That said, i have no idea what you're talking about and suspect you're just looking to rant. Same here.;P

And to be Uber fair, every third party library I use, I have hundreds of lines of code devoted to adding extra functionality to them that should have been there in the first place. Controls are so hard to get right for everyone and trying to just leads to horrible bloat. I'd like to see winform controls that are super basic but easily extendable with possibly a library of code samples or modules that you can easily add very specific functionality as required. Trying to be everything to everyone is the downfall of the Infragistics suite which is badly in need of a complete rewrite top to bottom.

Agreed. But consider this nuance. If I return a DateTime for use in a "between" clause in SQL, I have to serialize it to a string anyways because I can't use parameters. That's another oddity in itself. Can you say "SQL injection attack"? So, instead, I could write the SQL code to strip off the time when I pass in the string. Yuck. I just want something that's a G.D. date! And then you have the mixup between XSD date and time types, time zones, and, oh god, let's not go there today. X| Marc

Agreed. But sadly, a lot of this stuff falls apart when its used in conjunction with other gloriosky techniques, like data binding, automatic parameterization, validation, serialization, and so on. Taken one at a time, it's ok, but you start stringing these technologies together to form what you think should be a highly automatable process and *bang* it implodes on you. Marc
