In the Dialog form there are 2 buttons: 1) btnclose which closes the dialog form 2) btnOpenChild which opens a child form and then closes itself (the dialog form) What should i do to get my desired result? I have included the codes to all the forms so that it may become easier to understand what i want to do. I am a total newbie, so plz do bare with me! Any help will be gr8!

Well...I could not get your stuff to run (I think you forgot to paste the InitializeComponent() methods), so take this all with a grain of salt. You could just handle the closed event on your dialog form. Change / add this to form1private void button2_Click(object sender, System.EventArgs e) { WindowsApplication1.frmDialog dialog = new WindowsApplication1.frmDialog(); dialog.Closed += new EventHandler (vShowChild); //NEW LINE dialog.ShowDialog(); } //NEW METHOD private void vShowChild(object sender, EventArgs e) { WindowsApplication1.frmChild child = new WindowsApplication1.frmChild(this); child.Show(); }
Then just close the dialog:private void button1_Click(object sender, System.EventArgs e) { // What should i write here to show the child form // and also to close this form after the child form shows?? this.Close(); //NEW LINE }
Hope this helps, Bill

I think that someone else posted on this forum with exactly the same problem about a week ago... Look for a post titled : a parent-child problem, by Cem Louis try:http://www.codeproject.com/script/comments/forums.asp?msg=739514&forumid=1649#xx739514xx Cem's original source code is in the first message. I suggest a few changes in the second. This should get you on your way. Bill
