Can you please help me.

I have a program which is incomplete. I made a virtual keyboard but the left and right button is not working.

The plan was that every time the left or right button was clicked the text cursor also would move.

Any help is greatly appreciated.

Thanks.

推荐答案

也许您可以尝试使用TextBox.SelectionStart属性.

Maybe you can try the TextBox.SelectionStart Property.

void Left_Button_Click()
{
    if(myTextBox.SelectionStart > 0)
        myTextBox.SelectionStart--;
}

void Right_Button_Click()
{
    if(myTextBox.SelectionStart < myTextBox.Text.Length)
        myTextBox.SelectionStart++;
}
