moving from one textBox to another one

Hello,

I have three textBoxes (textBox1, textBox2 and textBox3).
Each textBox gets 2 digits.

For example
textBox1 -> 01
textBox2 -> 32
textBox3 -> 78

I need to press the tab botton or use the mouse, to move from textBoxi to textBoxj.
I have seen some windows forms in which the cursor automatically jumps to the next textBox after proper number of digits are entered.

I mean, for example when "01" is entered in textBox1, the cursor automatically jumps to textBox2 and so on.

How can I write such a code?


Thank you

Use the KeyDown or KeyPress event to validate the user input. If satisfied the textbox contains the required data, move onto the next textbox using the Focus() method. Eg:

Code:

---

int i;

if (textbox1.Text.Length == 2 && int.TryParse(textbox1.Text, out i))
    textbox2.Focus();

---

Building on what theobe said, instead of doing textbox2.Focus(), there's the Control.SelectNextControl() method to automatically set focus on the next control in the tab order.

Thank you :)

I checked "Control.SelectNextControl"

but I have a problem with the first argument "ctl as control". what is that?


what should I write in the code to call the function?

Code:

---

Control.SelectNextControl(???,true,true,true,true),

---

Check out the examples on this page.

You can pass it ActiveControl to pass it the control that currently has focus.

sorry but it doesn't work :(

if I dont press the tab botton, all the digits will be written in the first textBox

here is my code:

Code:

---

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            Control ctl;

            this.SetStyle(ControlStyles.Selectable, true);
            this.UpdateStyles();

            if (textBox1.Text.Length == 2)
            {
                ctl = (Control)sender;
                ctl.SelectNextControl(ActiveControl, true, true, true, true);
            }
        }

---

What am I doing wrong?

ctl.SelectNextControl(ActiveControl, true, true, true, true);

Remove the "ctl.", you should call it on the form, not the control.

Thank you so much :)
