问题描述
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();
