I'm in need of some assistance i finish creating an DataGridView and it gets DirectoryInfo from the desginated Directory
my code looks as following:
private void ReceivedFiles_InitColumns(ref DataGridView value)<br />
{<br />
value.Columns.Clear();<br />
dgv.AutoGenerateColumns = false;<br />
<br />
DataGridViewTextBoxColumn col = DataGridView_CreateColumn();<br />
col.DataPropertyName = "FullName";<br />
col.Name = "Naam";<br />
col.ReadOnly = true;<br />
value.Columns.Add(col);<br />
<br />
DataGridViewTextBoxColumn col1 = DataGridView_CreateColumn();<br />
col1.DataPropertyName = "extension";<br />
col1.Name = "Extensie";<br />
col1.ReadOnly = true;<br />
value.Columns.Add(col1);<br />
<br />
DataGridViewTextBoxColumn col2 = DataGridView_CreateColumn();<br />
col2.DataPropertyName = "LastAccessTime";<br />
col2.Name = " Laast Gebruikt";<br />
col2.ReadOnly = true;<br />
value.Columns.Add(col2); <br />
}
Tough now i need when i select and item from the DataGridView that i can remove an entry.
i already tryed :
private void btnDel_Click(object sender, EventArgs e)<br />
{<br />
dgv.Rows.Remove(dgv.Rows[dgv.RowCount -1]);<br />
}<br />
but that doenst work because i need IBindingList
if someone know how to get and remove entry function or some advise on how i could change my code so it works i appricate it 
Thanks in Advance

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.

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.

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

if(InvokeRequired)
{
Invoke(blah)
return;
}
lblStatus.text = "I like Crazy frog";
betonglasermur.FeedDwarf(pur_is, 17);
ProcessStartupInfo.AintNotCreateNoWindow = (false && !true) != (true || false) ? false == true ? true : false : (true != false && false);

This is always a bad idea.

How very ugly

Use delegates to call a form and tell it to change it's UI elements. You can then either set things up to invoke the UI changes, when in another thread, or if you prefer nasty solutions, you can just turn off the cross thread operations error.
If you read the article I link to in my sig, and pay particular attention to the section on how to google error messages.

I wondered about this.
I've always avaoided doing this, and used delegates, as is is seen as bad programming practice by some.
However if I know(due to the design on the application) that a cross thread call will not cause a conflict is it okay to turn off the error?
You always pass failure on the way to success.

I'd say that's entirely up to the conscience of the individual. If you're OK with it, then why not ? I've done it, when I ported a C# 1.1 app to 2.0 and found that a progress bar that showed loading progress from another thread was not working and I just needed a quick fix. The code had run fine for a long, long time, and it was the first time I'd seen the error.

//Declare Delegate :
private delegate void RefToFunction(string s);
//create an instanse :
RefToFunction handle = new RefToFunction(Function_A);
//Define the function :
private static void Function_A(string s)
{
lblStatus.Text = s;
}
//Invoke The Delegate (From where u need):
string status = "Hello World";
object [] param = { status };
this.Invoke(handle, param );
and thats it all 
Have Fun

Hi,
is there anyway I can get a listview to scroll when either the mouse is scrolled or the scroll bar is dragged?
I have created a custom listview control by overriding WndProc()

You can handle the mouse wheel scroll event and scroll your listview
