  1. POSending Data from child form to Parent Form TextBox
    text
    copied!<p>I have a Parent Form that holds a "HUD" with First Name, Last Name, etc. One of the child forms is a Search Form. When the user selects a member from the results that are displayed in a DataGrid I want the pertinent information to fill in the HUD. I created a HUD class with variables for each value and a method called UpdateHUD(). I am unsure how to get this working. I have a reference to the Search Form of the Parent form containing the HUD, like so:</p> <pre><code>public frmWWCModuleHost _frmWWCModuleHost; </code></pre> <p>This is the code I use to embed forms. I am not using MDI.</p> <pre><code> public static void ShowFormInContainerControl(Control ctl, Form frm) { frm.TopLevel = false; frm.FormBorderStyle = FormBorderStyle.None; frm.Dock = DockStyle.Fill; frm.Visible = true; ctl.Controls.Add(frm); } </code></pre> <p>Here is the code I am running on Cell Click on the Search Form. This is from before I tried implementing the HUD class.</p> <pre><code>private void dgvSearchResults_CellContentClick(object sender, DataGridViewCellEventArgs e) { _frmWWCModuleHost = new frmWWCModuleHost(); _frmWWCModuleHost.tbxHUD_LastName.Text = dgvSearchResults.CurrentRow.Cells[1].FormattedValue.ToString(); _frmWWCModuleHost.tbxHUD_LastName.Invalidate(); _frmWWCModuleHost.FormPaint(); } </code></pre> <p>Thanks in advance!</p> <p>~ Patrick</p> <hr> <h2>EDIT</h2> <hr> <p>dgvSearchResults_CellContentClick is now current. When I step through this code it is getting the correct Value here but it is never updating the actual HUD. </p> <hr> <h2>EDIT 2</h2> <hr> <p>Is my problem that I am declaring a NEW frmWWCModuleHost instead of passing a ref to the existing? I am still pretty weak in my understanding of this.</p> <hr> <h2>EDIT 3</h2> <hr> <p>I have "solved" this by doing the following: On the Parent Form where I declare the Child Form I pass <em>this</em> as a param. Then in the constructor of the child form I added _frmWWCModuleHost = m_parent; I have a UpdateHUD() method on my Parent form and I call it from the _CellClick event on the child.</p> <p>Now to rephrase my question; Is there anything glaringly wrong with doing it this way?</p>
