我需要设置passwordbox explicitlyin WPF里面的cursorposition。我看不出在passwordbox的selectionstart属性。

I need to set the cursorposition inside the passwordbox explicitlyin WPF. i couldn't see the selectionstart property in passwordbox.

任何帮助吗?

推荐答案

您可以尝试这样的事情,设置在passwordBox选择:

You can try something like this to set the selection in the PasswordBox:

private void SetSelection(PasswordBox passwordBox, int start, int length) {
    passwordBox.GetType().GetMethod("Select", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(passwordBox, new object[] { start, length });
}



之后,这样调用它来设置光标位置:

After that, call it like this to set the cursor position:

// set the cursor position to 2...
SetSelection( passwordBox1, 2, 0);

// focus the control to update the selection
passwordBox1.Focus();
