WPF：如何删除动态创建的文本框

Question

I am creating multiple textbox, I was wondering since I created these textbox dynamically how would I remove them or even update them?

For example in code

TextBox tb = new TextBox();
tb.Name = "Temp"

How would I remove or update textbox Temp

I cannot called Temp.Text = "Test"

Also I do not have access to tb.Text. I have created a bunch of textboxes and named them by a number textbox_1 . When a certain button is clicked I want to update the textbox that is clicked.

Answer 1

You can find that textbox from the container using Name like:

TextBox tb = (TextBox) this.someStackPanel.FindName("Temp");

then later

tb.Text = "Test";

To remove it you can do:

//First find the TextBox
TextBox tb = (TextBox) this.someStackPanel.FindName("Temp");
//Then remove it 
this.someStackPanel.Children.Remove(tb);

Answer 2

You need to call

parent.RegisterName("Temp", tb);

on the parent after creating the TextBox to register the name.

When you want to find the TextBox, call

TextBox tb = (TextBox) parent.FindName("Temp")

to get the TextBox.
