C＃动态添加的GroupBox向其添加控件后似乎为空

Question

I am having trouble with a little tool i am writing for myself. I am trying to have a Windows Form that shows a web browser and multiple, dynamically added groups of textboxes and comboboxes. The browser works fine and i can add textboxes etc. fine when not adding it to a groupbox, but rather to the main panel.

When trying to add the textboxes to groupboxes it works for the first groupbox, but every other one that followes stayes empty.

this is how my (simplified) code looks so far:

        //generate controls e.g.
        ComboBox dynamicComboBox = new ComboBox();
        dynamicComboBox.Name = "comboBox" + anzahlModule;
        dynamicComboBox.DataSource = new BindingSource(this.getInhaltComboBox(), null);
        dynamicComboBox.DisplayMember = "Value";
        dynamicComboBox.ValueMember = "Key";
        dynamicComboBox.Location = new System.Drawing.Point(153, Yloc + 25);
        dynamicComboBox.TabIndex = tabReihenfolge + 2;
        dynamicComboBox.SelectedIndexChanged += comboBox1_SelectedIndexChanged;

        ...do for all the others...


        //Get Interface and redraw
        GroupBox dynamicGroup = new GroupBox();
        dynamicGroup.Text = dynamicLabel.Text;
        dynamicGroup.Size = new System.Drawing.Size(600, 325);
        dynamicGroup.Location = button1.Location;
        dynamicGroup.Name = "dynamicGroupBox" + anzahlModule;
        dynamicGroup.Visible = true;

        dynamicGroup.Controls.Add(LabelComboBox);
        dynamicGroup.Controls.Add(LabelTextBox);
        dynamicGroup.Controls.Add(LabelTextBox2);
        dynamicGroup.Controls.Add(LabelInhalt);
        dynamicGroup.Controls.Add(LabelInhalt2);
        dynamicGroup.Controls.Add(LabelPictures);
        dynamicGroup.Controls.Add(LabelCheckBox);
        dynamicGroup.Controls.Add(LabelCheckBox2);
        dynamicGroup.Controls.Add(LabelLink);
        dynamicGroup.Controls.Add(LabelLink2);
        dynamicGroup.Controls.Add(dynamicTextBox);
        dynamicGroup.Controls.Add(dynamicTextBox2);
        dynamicGroup.Controls.Add(dynamicUeberschrift);
        dynamicGroup.Controls.Add(dynamicUeberschrift2);
        dynamicGroup.Controls.Add(dynamicComboBox);
        dynamicGroup.Controls.Add(dynamicPictureBox);
        dynamicGroup.Controls.Add(dynamicCheckBox);
        dynamicGroup.Controls.Add(dynamicCheckBox2);
        dynamicGroup.Controls.Add(dynamicLinkBox);
        dynamicGroup.Controls.Add(dynamicLinkBox2);
        panel1.Controls.Add(dynamicGroup);

this works if i add the stuff directly to panel1, but not when adding it to the groupboxes.

Can someone help my by giving me an idea on where the probleme might be or tell me what is actually wrong?

Thanks in advance.

Answer 1

Okay so I found my error and it is actually very simple, i was just too blind to see it :) I have positioned my textBoxes and so on in relation to a button that i afterwards moved. And that means that i tryed to display eg a label at point 750 / 300 in a group box that only has a size of 600x325, so it can not be visible. @Mikhail Neofitov thanks for the tip with multiple boxes at the same location, that lead to a solution.
