 Hi all,
I've been trying to have a simple checkbox in my datagrid using C# and it's being a pain to get it to work.
Here is the cenario.
I have a DataSet populated with a table "Employees" let's say. This table has fields such id, name, email.
All I want to do is to display an extra column in my datagrid that will display a checkbox for each row.
Note, there is no data associated with this checkbox. I just wanted the user to select some of the Employees from the datagrid by checking the checkbox. Then, when they click the button "Print", I will loop through the datagrid, get the selected ones and print.
Anyone can give me some instructions or example of how to do that?
I've been looking some people examples that do something similar. But they don't really show how to add an extra column to the datagrid with a checkbox for each record of your already populated dataset.
Please, any help will be appreciated.
Thanks to all.

You can add an unbound column to your datagrid and use a bool columnstyle for that unbound column. You can download a sample showing how to add an unbound column from:

Hello Clay,
Thanks a lot.
That's a pretty good link.
I will try it and I let you know when I get it to work.
Thanks again.

Ok, this makes me feel really stupid, but when I am looking at the code view in VS.NET I have the two drop down boxes at the top. This is very similar to VB6 where the left combo box lists all the objects(i.e. - buttons, grids, labels) and the right most combo box will list all methods and properties associated to what is selected in the left combo box. Why do I only see my forms for my project listed in the left combo box? Where are my objects that are on that form. How can I see all the methods and properties available to those object on my form? Please someone point me in the right direction. Thanks

On the top right is a dialog box where you can choose class view, solution explorer or resource view ( the last is useless, I've not seen anything there yet ,and I've added resources ). That's where you'll find your methods and classes.

Thanks,
Now I probably sound like I am complaining(I am), but is there any way that I can move this or have it view the methods and properties the "old-fashioned way" or should I just give in?
Anyway, Thanks again Christian

VB.NET uses those drop down boxes as you expect, so the answer is yes, but you would have to code in VB.NET
Not that that is a bad thing

Yes, you can drag/redock and size that dialog.
I'd also guess you'd get something like the old Wizard bar if you right clicked in the toolbar area and checked what other toolbars you can make visible.

What would be the "old-fashioned way"?
After allot of erratic *docking-window* rubber-band snapping, swearing, and some crying, I finally have the IDE back in a state where it almost feels like a *better* Visual Studio 6.

This is what I meant, I will be fine with how it is now, I was only inquiring.

That’s ok; I am coming from Visual C++ IDE, not the VB IDE, same problems, different perspective.

CP has a couple of nice examples of how to download a file via HTTP. Can someone point me to a code snippet that demonstrates how to send a "HEAD" request for a resource (eg: http:/foo.com/mumble.html) and read the returned result? Thanks,

I am deriving a new control from ListBox in which I wish to
intercept certain windows messages.
From what I can see, I need to override WndProc(ref m message) and then examine m.Msg. The trouble is, constants for Windows Messages such as WM_VSCROLL, do not seem to be defined anywhere.
Am I working along the right lines?
Rob.

Unfortunately the Windows messages aren't defined anywhere in .NET; you'll have to pull the values out from the appropriate header file from the Platform SDK.
HTH,

hi!
I ask this few days ago. but no one answert me..
therefore I ask over again..
what I want to do....
when an user checked one item in the ListView the other items must come
hidden.
or:
when an user checked one item in the ListView the other items must come
hidden and after the user cheched the second time
at this item all items was visible....
(I will make it to allowed the user to checked only 1 item)
the even I will use is:
private void displayCustomerListView_ItemCheck(object sender,System.Windows.Forms.ItemCheckEventArgs e)
{
for (int i = 0; i < displayCustomerListView.Items.Count; i++)
{
if(!(displayCustomerListView.Items[i].Index == e.Index))
{
//and here must stand the code that make the Items[i] checkbox unvisible or unable to check
}
}
}
have anyone an idea how I can make this?
(at best would help me a code sample in C#)
big THX!!

I want that the user make one choise from the list view. not multiple
choice.

To uncheck an item:
displayCustomerListView.Items[i].Checked = false

If only one item can be selected why are you using the CheckListBox in the first place? Its very nature implies that you can select multiple items.
If you only want to allow one item to be selected you should use a normal ListBox or create your own control that does what the CheckListBox does but uses Radio buttons instead of check boxes.

Does anybody else got that problem?
When I use two controls in a panel, one with docking style 'Fill' and another with docking style 'Bottom' (for example, a text field and a HScrollbar), I can write text in the text area that gets behind the scroll!! e.g. the text area "thinks" it can paint in an area that actually belongs to the scrollbar. 
???

Sure, right click the ScrollBar and select 'Send to Back'.
