I have a custom control here and I need to do the same thing with it without deriving from Panel
So, what features of Panel are you talking about? A panel is basically just a container for another collection of controls. But that's a property of Control, not Panel. It provides grouping for radio buttons. But that should be easy enough to implement yourself. Similarly with Panel's enable/disable feature--disable the panel and it's child controls are disabled. The only other thing about panels is the AutoScroll capability, which again may or may not be necessary but is fairly easy to recreate.
And why not derive from Panel? If that doesn't work, then you can derive from Control but contain a panel, and pass through whatever functions you want to the Panel object and provide your own drawing.
Maybe my article will help too: http://www.codeproject.com/cs/miscctrl/csoutlookbar.asp[^]
Good luck!

Sorry for not explaining this well enough.
What I was looking for is an attribute, or something simple to tell the VS.net designer to allow me to add child controls to my custom control. I don't need scrolling or anything extra. Just a way of treating my control as a control container.
Thanks for your help.

By the sounds of it, what you need to do is create a designer class for your control. Control designers are a complex subject, so I'd suggest looking up the MSDN doco, or look at some CP articles such as Jerry McGuire's designer for the Magic docking library for some insight.

This should be simple to answer, but MSDN comes up blank.
I've noticed some C# code with an @ in front of string literals:
MyNameIs(@"Alvaro");
What is it for?
Thanks in advance,
Alvaro

the @ supresses escaped characters... for example:
a windows path of C:\Program Files\ would normally have to be defined like this:
string path = "C:\\Program Files\\";
because back slash is a character which must be escaped.
if you use @, then it ignores special characters:
string path= @"C:\Program Files\";
hope this helps.

It also lets you write multi-line string constants.
The feature name is "verbatim string".

You mean like in C++?
String ml = @"I love "
".NET.";

I creatd a custom control and I'm having re-painting problems. When another window is moved in front of the control and screws it up, it doesn't repaint. Do I need to set any style for the control to make sure it repaints when needed.
|

|
|

You are repainting in the OnPaint method, right? There's no such thing as AutoRedraw in C# unless you make there be one.

I fixed it already. Thanks for the help.
All i did was set up wndproc and on WM_PAINT tell the control to paint

Is that a better solution than invalidating that portion of the parent control (and the parent's child controls) in that region?

Well, overriding the WinProc allows you to catch specific messages, allowing you to customize the way the application works, in this case, when repainting is done.

i posted a reply and it dissappeared 
anyway , invalidating a control should do the job, eg:
button1.Invalidate();

I have 2 forms. ( Form1 & Form2 )
Form 1 has a datagrid and an advanced search button which shows Form 2.
When the information in form 2 is submitted, I want it to hide and populate the datagrid of form 1.
The problem is that I can not seem to access any variables or functions of form 1 from form 2.
am i on the right track with the code below?
<form1>
<br />
private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
Form Form2 = new Form2();<br />
Form2.Show();<br />
}
<form2>
<br />
private void btnFindContact_Click(object sender, System.EventArgs e)<br />
{<br />
Form1.dataGrid1.SetDataBinding(ds,"Contacts");<br />
this.Hide();<br />
}

It is always a question of level of accessibility. When trying to access variables or methods of a second form on a first form you have two options:
1. Change the accessors of the variables assigned to the controls in questions (in most cases I would not recommend that).
2. Use properties to indirectly access variables assigned to the controls (recommended in most cases).

sorry i don't completely understand your answers, but i'm trying.
#1: i think i have tried this by changing from private to public, and then trying to access the variable from form 1 with: Form2.TextBox1.Text .. however i get compilation errors that it does not recognize TextBox1
#2: could you go into a little more detail? or if you know a good link, send me there?
i've been working at this for the last 2 days and can't seem to come up with anything except for working with a dialog box.

It would depend on the access you have on the grid variable in Form one plus your form2 would have to have knowledge of your form1 structure which is calling it.
You have two ways:
1) Add a Property and a variable to your Form2 of a DataGrid.
private DataGrid parentDataGrid = null
public DataGrid ParentDataGrid
{
get { return parentDataGrid; }
set { parentDataGrid = value; }
}
In your Form1 when you call the Form2:
private void button1_Click(object sender, System.EventArgs e)
{
Form2 form2 = new Form2();
form2.ParentDataGrid = dataGrid1;
form2.Show(); (or .ShowDialog)
}
In Form two you simply:
if(ParentDataGrid!=null)
{
ParentDataGrid.SetDataBinding(ds,"Contacts");
this.Hide();
}
2) In form2 do:
Form1 form1 = ParentForm as Form1;
form1.datagrid1.DataBinding(ds,"Contacts");
this.Hide();
And make sure in Form1 you either change the private or protected access to the datagrid1 to public or make it a property of the datagrid1 in form1 as we did above and call that property in Form2.

How do I know in the datagrid when a new row is being selected.
I have textboxes showing more data and need to update them when a row changes.

Hello,
I have been developing a program.
There are lots of forms, and I do need to show some of them(when they become necessary)
I was using a method to show a form inside a picturebox.
I have used the SetParent and GetParent apis to perform the operation that I wish in Visual Basic 6.
I was able to show a form inside a picture box or frame.
Show I can Load and Unload forms that I want.
How can I do that in C#?
Thank you for your time.
Best Regards

One easy way that allows tabbing to work properly and looks natural is to use UserControls for your forms and create them as needed. You would place a panel control on your form where you want the embedded form to show and in your code, you would create the user control you want displayed and add the control to the Panel's Controls collection. When you want to change to another UserControl, you can clear the Panel's Controls collection and add the new one.
Another way is by using a tab control and convering the tabs.
And yet another way is to set the form's border you wish to embed to nothing and the control box to nothing (last step many not be needed) and set the Form's TopLevel to false; You can then add it to the Panel's Control list and use a Show() on the form. This will however cause you tabbing problems. I never went further than this since the UserControl method above gave me all that I could desire.

Hi,
how can I get the number and names of available child-forms within a Mdi-application. I need to know after starting the mdi-app, without having any child-form open.
Thanks
