But How does the dialog know about the event ?
What i need to know ( and does not understand ) is the dialog know about the existing of the click event before i create the connection between the dialog and the User Control ?
Because i need to do it in late banding and i don't want to create connection between the dialog and the User Control in the design time - i want to create this connection in run time -
Can i do it ?

myControl.Click1 += new MyControl.ClickHandler(yourClickHandlerMethodInTheDialog);
myControl here is an instance of the user control whose class name is MyControl.

The instance myControl only exists at run time in all cases (even if you're using the VS Designer).

Hello,
In my C# Windows form, I have a datagridview which has a column name "id". Now, I want that, when the form is loaded, the gridview sort the column by descending order. I did not find any snippet to do so. Would you please help me by giving me a snippet.
Regards

Sort by ID in descending order while fetching data from database before you show in DataGridView.

Hi,
Thanks for your suggession. Actually I did that before, but for some other conflict in my project, I had to remove that Ordering in the database query. So, I thought, there could be some way to sort only that specific datagridview and not other gridviews in my form.
Regards.

Hi,
I have my way to sort DataGridView like this, but improve it by your self:
Step 1:
- I create stored procedure "sp_sort" that query is "SELECT * FROM tablename ORDER BY id DESC"
Step 2:
- On form load you type this :
<code>
SqlCommand cmd = new Sqlcommand("sp_sort", conn);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
adapter.Fill(dt);
myGridView.DataSource = dt;
</code>
Regard,
Edwin

I have a MainForm which is MDI parent to all other forms. I want the to display the child forms as tab pages inside the MainForm. Is it possible? Can anyone help me with this please?

You don't need an Mdi setup to do that. It is possible to do in tab pages, though I'm not saying it's a good idea. You will you will not get designer support for this. You have to create your forms as if they were normal, then you have to modify the forms and add them to the appropriate TabPages in your code.
There is a hidden little property of a form call TopLevel. Set this property to False, then you can add the form to any container that holds Control objects.

Is it possible to write an enum like the code below.
public enum BloodGroup<br />
{<br />
None = 0,<br />
A+ = 1,<br />
A- = 2,<br />
B+ = 3,<br />
B- = 4,<br />
O+ = 5,<br />
O- = 6,<br />
AB+ = 7,<br />
AB- = 8<br />
};

No. My compiler complains about the first +. What compiler are you using to have to ask this question?
|
|
|
|

What about writing the enum using APos, ANeg, BPos, BNeg etc...?????

I used C# in Visual Studio 2005

No, it's not. You can only use the chracters legal in varible names.
|
|
|
|

Sorry about my first post, I was a bit abrupt. You probably had tried using those names, found the compiler didn't like them, and what you actually wanted to ask was how to fulfil your requirement of an enum for blood groups. The rule that prohibits those characters in names is not only applicable to enums, but to all C# identifiers.
If you need the blood group name, with the '+' or '-', you will have to use a BloodGroup class, has a property indicating the group, and another indicating the string name.

He can also use the Description attribute. Lots of articles here on CP regarding enum description.

No, but look at articles on Enum Description, like this one.[^] Read the comments to the article as well.

There is a wonderfully long and detailed multi-part Article here by Corinna John, and now she has aggregated code from all the articles into a framework here[^]. It doesn't cover those carriers specifically, but it's the only one I know of.

Use a property if you want to get info while the forms are created. Otherwise if you want to send data to a newly created class (form) send it to the class (form) constructor.
Hope this helps.
Mark.
