I have a mainform that contains a panel in which different MDI child forms are displayed. The controls in the MDI child got Anchor = Left, Right, Top, Bottom to resize.
The problem is the resizing of the controls in the MDI child when the main form is resized. I got it working with the following code:
private void MainForm_Resize(object sender, EventArgs e)
{
foreach (Form f in panel.Controls.OfType<Form>())
{
f.WindowState = FormWindowState.Minimized;
f.WindowState = FormWindowState.Maximized;
}
}
The problem is that the controls in the MDI child permanantly change their location when you are resizing. Is there some way to call a Resize method?
For those who got the same issue:
You need to set the Dock property to DockStyle.Fill for the MDI child. Else it just doesn't resize the controls.

i think you have to use USER CONTROL instead of a form. Add a usercontrol at your prject and here is the code :
for (int i = panel2.Controls.Count; i > 0; i--)
{
panel2.Controls[i-1].Dispose();
}
//add user control you want
UserControl1 uc = new UserControl1();
panel2.Controls.Add(uc);
I prepared the form with using "SplitContainer tool".I added Treeview into left side of that SplitContainer. next i added to that treeview two Node such as hide and show and also i prepared a "child form". I need to do, Chile form SplitContainer load to right side when I click on the Node show and hide child form when click on the hide node.i can show chile form but can not hide it.please help me to do this.below i attached code which i used to "Show"
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
UserControll.UscCreateUser UscPerobjForm = new UserControll.UscCreateUser();
string Tree = (string)e.Node.Tag;
if (Tree == "1")
{
UscPerobjForm.TopLevel = false;
splitContainer1.Panel2.Controls.Add(UscPerobjForm);
UscPerobjForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
UscPerobjForm.Dock = DockStyle.Fill;
UscPerobjForm.Show();
//Show part
}
else if (Tree == "2")
{
// Hide part
}
}
I need to Hide part.
Try using http://dockpanelsuite.com/ where you can have the tree view implement in a Form class docked on Left while the Child Form dock the center.
I would like to create TabPages (fill docked with frmCalculationReport) as child forms of a MDI, so that I can switch active TabPage from ToolStripMenu such as "Window" pull down menu.
I have one tabControl1 fill docked in MDI MainWindow with ToolStripMenu of that "Window".
When I click one ToolStripMenu item such as performCodeCalculationsToolStripMenuItem from MDI MainWindow, I would like one TabPage (with a docked frmCalculationReport) added on tabControl1 as a child form of MDI MainWindow. Following are the codes. But, I do not know how to add the TabPages as child of MDI MainWindows. Any suggestion and comments will be greatly appreciated.
private void performCodeCalculationsToolStripMenuItem_Click(object sender, EventArgs e)
{
string title = "CalReport";
TabPage myTabPage = new TabPage(title);
tabControl1.TabPages.Add(myTabPage);
CalculationReport frmCalculationReport = new CalculationReport();
frmCalculationReport.TopLevel = false;
frmCalculationReport.Visible = true;
frmCalculationReport.FormBorderStyle = FormBorderStyle.None;
frmCalculationReport.Dock = DockStyle.Fill;
tabControl1.TabPages[tabControl1.TabCount - 1].Controls.Add(frmCalculationReport);
tabControl1.SelectedIndex = tabControl1.TabCount - 1;
}
I have a main application form, I've set the IsMdiContainer property to TRUE
I have a panel in the main application form on the top but when I open the ChildForm it opens behind the panel. How do I set location relative to the bottom of the panel + maximize the window?
As Hans said in comments, Set the Dock property of Panel to Top for example. And add your Mdi Childs this way:
Example:
private void MdiTest_Load(object sender, EventArgs e)
{
//Codes for test only
var f = new Form();
f.Controls.Add(new TextBox());
f.MdiParent = this;
f.Show();
}
Note:
You can access to MdiClient control this way:
var mdiClient = this.Controls.OfType<System.Windows.Forms.MdiClient>().First();
Then you can do anything with it if you need. It is a Control like other controls.
Normal State:
Maximized State:
I have an MDI parent and MDI child. I want to hide the icon of the child form in a maximized state, so I tried the following:
g.WindowState = FormWindowState.Normal;
g.ShowIcon = false;
g.Show();
g.WindowState = FormWindowState.Maximized;
The showicon value of the child form is set to false, but when it's maximized, it still shows an icon:
MDI requires these frame decorations to be present, it will misbehave in various ways when you try to hide them. A simple workaround is to create an icon that's entirely transparent.
In the ItemAdded event:
if (e.item.Text == "" )
{
e.item.Visible = false;
}
