MDI parent MDI child issue

[gerrybrennan]

Hi I have an app with its main form MAIN which is an mdi container. One of the options from this MAIN is to show a database record in a new dialog (DIALOG_A). This new dialog is a mdi child and its mdiparent is MAIN. Now another operation that MAIN can perform is to create another new dialog (DIALOG_B). This also is a child mdi and its mdiparent is MAIN. However, from DIALOG_B .... i would like to call DIALOG_A also. I am getting problems however becuause Dialog_A is not an MDI container. Could some one suggest some help. Thank you very much.

Does call means opening the form? If you can show some code it would be better. Although you can create the instance of form A and open it using Show method. You can set it's MDI parent as the Main form like this:

FormA frmA = new FormA();
frmA.MDIParent = this.MDIParent;
frmA.Show();

This code would come in the FormB and MDIParent of the FormB should be MainForm.

Could you please clarify:

Does this mean you wish to be able to create a new Dialog_A from Dialog_B, or do you want to Call some function in Dialog_A from Dialog_B?

Hi .. Yes call means -> Instanciate the form. Thank you.

Yes -> Does this mean you wish to be able to create a new Dialog_A Thank you.

In that case the code I had posted should work for you. Or it does not?

Are you saying that you want MAIN to launch a new form, DIALOG_B, and make it an MdiChild of MAIN, then DIALOG_B creates a new instance of DIALOG_A and make it an MdiChild of DIALOG_B??? You can't do that. An MdiChild form cannot also be an MdiParent at the same time.
