C#:
I have to develop project that looks like "Master & child" Pages in ASP.net, i.e., "MDI-Parent & MDI-child" But here i need not want the titlebar for child form and should not have child form minimizeble (i.e, ChildForm should be fit in the content part of a MDI-Parent form).

Here my idea is, First i have to design a MDI Parent form with companies Logo picture bar & 3 buttons(Rounded Rectangular image buttons) namely "EntryForm" button, "UpdateForm" button, "ViewForm" button. In that if i clicked "EntryForm" button, then the Entryform MDI-child should be should in that MDI-Parent Form and as the same for other two buttons also. Note: Even though the MDI-Child form should works as it as independent form.

MDI is the wrong way to go if you're wanting to approximate master pages in ASP.NET. The right way to go is custom user controls.

I'd start here.

tanx.. for ur fast reply.

At Present i'm using the Custom User controls, But getting confusions in linking the custom user control forms. I have used (designed) 3 custom controls (UC_EntryForm, UC_UpdateForm, UC_ViewForm) as a child form looks. And One Normal Window Form with BackGround Companies Logo picture and a Panel (into which the custom controls will shown) & 3 buttons. For each button has needs a code to load a specific custom user control. How?

The button click handlers should be handled by the main form that contains them. This form should perform operations to instantiate and position the user controls that are the sub-controls you want to show.

That being said, you might want to look into the TabControl instead. It might be exactly what you're looking for, actually.

Hi,

You might want to add theusercontrol to the controlcollection of the form:

if (c != null)
{
this.Controls.Remove(c);
c = new UserControl1();
this.Controls.Add(c);

}

Please take a look at the project here:

If there are unmanaged objects in your usercontrol , you might need to call : c.Dispose() to release them.

Hope it will help,
Harry

Hi,

Does the code in my post work?

When we define a class with unmanaged resources , we need to release it in our code, since CLR normallydoes not release it.
So we can release these unmanaged resources in finalizer method. however, it will take long time to release it ( You might want to take a look at some artical about generationof GC) . We can make up adispose method to doreleasingwork , it can be called by users when theydon't need the object that references unmanaged resourcesto reduce the timeto release object .

If you are not familiar with the concept , you might need to create a new thread about specific quesiton.
