Not able to add a System.Windows.Controls.TextBox to groupbox controls in C#

Question

Is there any way to add a System.Windows.Controls.TextBox to GroupBox controls in C#?

I tried the following but it doesn't show up in the groupbox:

 public System.Windows.Controls.TextBox textBox6 = new System.Windows.Controls.TextBox();
 public System.Windows.Controls.TextBox textBox7 = new System.Windows.Controls.TextBox();
 public ElementHost sumtext = new ElementHost();
 public ElementHost loctext = new ElementHost();

 private void Form1_Load(object sender, EventArgs e)
    {
        textBox6.Name = "Summary";
        textBox7.Name = "Location";

        textBox6.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
        textBox6.FontSize = 12;
        textBox6.SpellCheck.IsEnabled = true;

        textBox7.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
        textBox7.FontSize = 12;
        textBox7.SpellCheck.IsEnabled = true;

        groupBox4.Controls.Add(sumtext);
        sumtext.Dock = DockStyle.None;
        sumtext.Width = 246;
        sumtext.Height = 35;
        sumtext.Child = textBox6;
        sumtext.Location = new Point(3, 33);
        sumtext.Visible = true;
        sumtext.Enabled = false;
        groupBox4.Controls.Add(sumtext);

        groupBox4.Controls.Add(loctext);
        loctext.Dock = DockStyle.None;
        loctext.Width = 246;
        loctext.Height = 35;
        loctext.Child = textBox7;
        loctext.Location = new Point(3, 90);
        loctext.Visible = true;
        loctext.Enabled = false;

        this.Controls.Add(sumtext);
        this.Controls.Add(loctext);
    }

I need to use System.Windows.Controls.TextBox rather than Form.TextBox as I need it for spell check.

Any help would be greatly appreciated!

You can put WPF controls into Winforms by using the ElementHost like he's doing — wangburger, May 25 '11 at 21:29
is groubBox4 `System.WIndows.Controls.GroupBox` or `System.Windows.Forms.GroupBox` ? — Bala R, May 25 '11 at 21:39

Are you sure its not showing up? both ElementHosts are disabled and your never setting textbox6 or textbox7 with Text. You are giving them a name but nothing for textbox6.Text — JMcCarty, May 25 '11 at 21:52

I changed the Enabled property of the sumtext, and removed the other box to shorten it: This code works for me:

    public Form1()
    {
        this.Load += new System.EventHandler(this.Form1_Load);
    }

    public System.Windows.Controls.TextBox textBox6 = new System.Windows.Controls.TextBox();
    public ElementHost sumtext = new ElementHost();
    private System.Windows.Forms.GroupBox groupBox4;

    private void Form1_Load(object sender, EventArgs e)
    {
        this.groupBox4 = new System.Windows.Forms.GroupBox();
        this.SuspendLayout();
        // 
        // groupBox4
        // 
        this.groupBox4.Location = new System.Drawing.Point(57, 63);
        this.groupBox4.Name = "groupBox4";
        this.groupBox4.Size = new System.Drawing.Size(591, 238);
        this.groupBox4.TabIndex = 0;
        this.groupBox4.TabStop = false;
        this.groupBox4.Text = "groupBox1";
        // 
        // Form1
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(706, 478);
        this.Controls.Add(this.groupBox4);
        this.Name = "Form1";
        this.Text = "Form1";
        this.ResumeLayout(false);
        textBox6.Name = "Summary";

        textBox6.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
        textBox6.FontSize = 12;
        textBox6.SpellCheck.IsEnabled = true;

        groupBox4.Controls.Add(sumtext);
        sumtext.Dock = DockStyle.None;
        sumtext.Width = 246;
        sumtext.Height = 35;
        sumtext.Child = textBox6;
        sumtext.Location = new Point(3, 33);
        sumtext.Visible = true;
        sumtext.Enabled = true;
        groupBox4.Controls.Add(sumtext);
    }

If you move your group box location to a different point does it work? mine is located at point 271, 268 but the textboxes are at 3, 33 on the main form and not in the groupbox. — user770344, May 26 '11 at 00:45
@user770344: at the bottom of your code you have these 2 lines: this.Controls.Add(sumtext); this.Controls.Add(loctext); This is probably causing your issues. Remove them? — David, May 26 '11 at 15:06

Is this code actually getting called? Has groupbox 4 been added to the form yet?

You should not be adding your ElementHost controls to your Form AND your GroupBox, it appears to be confusing .NET. Keeping your original code exactly as-is but commenting out these two lines makes it work:

    //this.Controls.Add(sumtext);
    //this.Controls.Add(loctext);

Also... I don't think it's hurting anything, but you don't need to do this twice:

    //groupBox4.Controls.Add(sumtext);

Looks like commenting out those two lines worked! I think I see what happened now, I added the control to groupbox4 then readded it back to the 'this' removing it away from groupbox. Thank you!!! – user770344 May 26 '11 at 04:08
