UWP C# 滚动到文本框的底部

问题描述

如何滚动到 UWP 应用的文本框底部?

How do you scroll to the bottom of a TextBox for a UWP app?

随着我向 UWP 的过渡，这是尚未直截了当的问题之一.

With my transition to UWP, this has been one of the questions that hasn't been straight-forward.

我以前可以用这个:

textBox.SelectionStart = textBox.TextLength;
textBox.ScrollToCaret();

但是，这不适用于 UWP 应用

But, this doesn't work for UWP apps

推荐答案

如果有人需要在 UWP 应用中滚动到 TextBox 的底部:

If anyone needs to scroll to the bottom of a TextBox in UWP apps:

https://code.msdn.microsoft.com/windowsapps/How-to-scroll-to-the-a8ea5867

privatevoidTextBox_TextChanged(objectsender,TextChangedEventArgse)
{
    vargrid=(Grid)VisualTreeHelper.GetChild(textBox1,0);
    for(vari=0;i<=VisualTreeHelper.GetChildrenCount(grid)-1;i++)
        {
            objectobj=VisualTreeHelper.GetChild(grid,i);
            if(!(objisScrollViewer))continue;
            ((ScrollViewer)obj).ChangeView(0.0f,((ScrollViewer)obj).ExtentHeight,1.0f);
            break;
        }
    }
}

其中 textBox1 是您要滚动到底部的文本框.

where textBox1 is the TextBox you want to scroll to the bottom.
