从AutoCompleteBox中选择项目后，从头开始显示文本 [英] Showing Text from begining after selecting item from AutoCompleteBox

问题描述

我正在使用自动完成"框，从下拉列表中选择项目后，该项目未显示开始文本，仅显示了结束文本


假设文本框的宽度为100，如果自动完成中选中项的长度较大，则自动完成而不是显示从开始显示的文本，而是仅显示字符串的末尾(即文本框中的可见部分)

请帮助我...

plz help me in this ...

推荐答案

AutoCompleteBox由TextBox和少量组件组成.该控件不公开TextBox控件.因此，除非您派生并自定义控件，否则您将无法实现自己的想法.

从AutoCompleteBox派生AutoCompleteBoxEx并添加公共属性/方法以返回控件内部使用的TextBox.然后，您可以尝试以下示例.

试试，

AutoCompleteBox is made up of TextBox and few components. The control does not expose the TextBox control. So you cannot achieve your idea unless you derived and customize the control.

Derived AutoCompleteBoxEx from AutoCompleteBox and add a public Property/Method to return the TextBox used inside the control. Then you can try the below example.

Try,

textBox.CaretIndex = 0;

在您从自动完成"框中选择项目之后

after you selected the item from the AutoComplete box

您好，我在一周之前获得了解决方案，因此自动完成"框由许多内容组成，其中文本框也是其中之一，因此我们需要获取该文本框通过遍历树来自动完成

在autocomplte框的最后一个焦点内，我们可以像
那样放置

hi I got solution before week itself ,the Autocomplete box is composed of many things among that textbox is also one ,so we need to get the textbox from the autocomplete by traversing the tree

Inside the last focus of autocomplte box we can put like

AutoCompleteBox autoObject = sender as AutoCompleteBox;
         TextBox textObject = VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(autoObject, 0), 0) as TextBox;
         textObject.SelectAll();
         textObject.SelectionLength = 0;

这样文本的开头部分将在自动完成的最后一个焦点上显示

干杯，

so that the begining part of text will be diplayed on autocomplete last focus

Cheers,
