Why not download Reflector and find out for yourself? This is a fantastic tool that is invaluable if you want to find out how things work rather than just accepting that they do.

looking at one implementation rather than reading the documentation[^]

More a general hint that there are other options. Sure - read the documentation, but don't accept that it's right - actually research for yourself. After all, the MSDN is well known for its accuracy and consistency.

Thanks for taking the time to have a look - I didn't find/see a link to this documentation in the msdn documentation on TryParse(), but unfortunately this documentation doesn't answer my initial question. When I get a little time today, I will attempt to follow Mr O'Hanlon's suggestion. (I have avoided Reflector in the past as it seemed a bit scary)

DateTime.TryParse() has an overload that takes a IFormatProvider parameter and puts you
in charge of what is acceptable and what is not.

Nope. I haven't.

I assume that this is implemented by creating a NotifyIcon control. Use a timer that fires periodically, checks to see if there are any messaged and updates the NotifyIcon.Icon property accordingly.

foreach (DataGridViewRow selectedrow in dgv.SelectedRows)
if (!selectedrow.IsNewRow)
dgv.Rows.Remove(selectedrow);
This will remove all the selected items.

I think you're getting an error because you're trying to delete the new row which is the last row.

Thanks for helping,
I used it and ran an quick test i keep getting the IBindingList error
Is there an way that i can create or connect IBindingList to my DataGridView code?

You're welcome.
How are you filling the data? Can you provide more information about the exception? If possible, post all code related to this DataGridView.

Thats everything releated to the datagridview.

That's where everything goes wrong. You're binding the grid to an array. Arrays do not impliment the IBindingList interface.
You should put your data in a data structure that implement the IBindingList. You should put your data in a DataTable and then use it as the DataSource of the DataGridView.

Hello Everyone.
I am creating a custom control. I need to add, amongst its properties, a bunch of lists.
One of those is a list of System.Drawing.Color objects.
I create the property as usual:
<br />
private List<System.Drawing.Color> _Colors = new List<System.Drawing.Color>();<br />
public List<System.Drawing.Color> Colors<br />
{<br />
get { return _Colors; }<br />
set { _Colors = value; }<br />
}
This, however, seems not to get the things done quite right. Actually, I get this error:
<br />
Cannot create an object of type 'System.Collections.Generic.List`1[[System.Drawing.Color, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a]]' from its string representation '(Collection)' for the 'Colors' property.<br />
Do I need to add something to my code to have this property working?
Thanks in advance - any help would be much appreciated.

I think this means you have a control you can serialise, and you can't serialise a list of colors.

You are getting the error because 'Colors' is a class in .Net Framework. So just rename your property from 'Colors' to something else.

Another rentacoder job gone wrong ? Tell your client you have no idea how to do the job, and next time, take jobs you know how to do.
Or, read the article I link to in my sig.

Hi,
I make public some controls on the form and I new a class in a windows form and send this (current instance of the form) to that class as parameter of constrauctor.
Now when I want to set the Text property of a lable of form in the class this error appears:
"Cross-thread operation not valid: Control 'lblStatus' accessed from a thread other than the thread it was created on."
How can I do this?
Best wishes
