[英]The Textbox doesn't show the blinking cursor on clicking or when it has focus
In the textboxes from the code below, the blinking cursor doesn't show even after i click the textbox or when it has focus.I'm posting this big a code because i think perhaps it's the parent element properties that are somehow interfering with the texboxes but I can't seem to find a solution for this. 在下面代码的文本框中,即使我单击文本框或获得焦点后,闪烁的光标也不会显示。我发布了这么大的代码,因为我认为可能是父元素属性在某种程度上干扰了texboxes,但我似乎找不到解决方案。 Can someone please help.
有人可以帮忙吗?

Note:- When i start typing the caret appears but disappears when i clear the textbox values. 注意:-当我开始键入插入符号时,出现该符号,但当我清除该文本框值时消失。
It looks like you problem might comes from the ScaleTransform. 看来您的问题可能来自ScaleTransform。 If a TextBox is scaled to less then it's original size it's cursor disappears.
如果将TextBox缩放为小于其原始大小,则光标消失。 This happens because the TextBox caret is with Width of 1 and when scaled down it becomes less then 1. So it's not visualized at all.
发生这种情况是因为TextBox插入符的宽度为1,并且按比例缩小时它小于1。因此根本看不到它。
As a workaround make the minimal possible size as default so UI is only scaled up. 解决方法是将最小大小设置为默认值,以便仅按比例扩展UI。
Another workaround it to create a custom caret like it's shown here WPF TextBox Inside ViewBox loses Cursor on resize 另一个解决方法是创建一个自定义插入记号,如下所示: WPF TextBox Inside ViewBox在调整大小时丢失游标
