  1. POC# call MDI child from child form
    text
    copied!<p>I have these forms:</p> <p>MainScreen - <em>MDI container</em><br> DataBaseOutput - <em>child</em><br> NewAnime - <em>child</em> </p> <p>DataBaseOutput has a tab control that holds datagrids, each for different tables. I use an access database. </p> <p>In those tabs, there is a menustrip, where the functions "New", "Edit", "Delete" etc. will be called from. Now when I'm on the first tab's menustrip and click on "New" I want to open the form "NewAnime", inside the MDI container. This however, is not working as I planned. At first I tried to just call it from the childform (DataBaseOutput). This resulted in opening a new form instead of a child. when I made it a child it was not showing up.</p> <p>Then I triend lots of things, but I still haven't figured it out.</p> <p>This is the current code for calling the form. It calls the form with a method in the main form:</p> <pre><code>private void NewAnime_Click(object sender, EventArgs e) { MainScreen main = new MainScreen(); main.mShowForm(2); this.Close(); } </code></pre> <p>Method in the main form:</p> <pre><code>// Forms for MDI Parent DataBaseOutput OutputForm = new DataBaseOutput(); NewAnime AddAnime = new NewAnime(); // How i made them childs (this is at the InitializeComponent(); part) OutputForm.MdiParent = this; AddAnime.MdiParent = this; public void mShowForm(int formnumber) { switch (formnumber) { case 1: OutputForm.Show(); break; case 2: AddAnime.Show(); break; } } </code></pre> <p>Does anyone have a clue of what i'm doing wrong and maybe has a better idea? This might be a bit too much working around, but as I said, it's my first time using MDI forms and i'm just trying to get it to work.</p>
