jabdp常用控件

由 喜夏-厌秋 提交于 2020-03-11 16:03:50
应用好不好用，用户体验是非常重要的。jabdp已经集成丰富的UI组件，并且与字段绑定好。 1、下拉框（combobox） 下拉框是最常用的控件，它是怎么实现的呢。 在字段属性里，编辑类型选【comboBox】，然后【数据源设置】，数据源设置有三个选项，分别是固定值、sql语句、模块。 选项一：数据源为固定值 数据源为固定值的比较简单。字段key是存储在数据库的实际值，caption是下拉框展示出来的值。例如产品类型是调味料，存放到数据库里便是1。这样方便使用和维护。 保存更新，下拉框即可生成。 数据源为固定值虽然配置简单，但是缺乏灵活，比较适合选项不多的情况。 选项二：数据源为模块 当选项比较多的时候，可以引用其他的模块或字典表作为数据源，这样便于修改和维护。 这是上一章建的数据字典为例子，把它作为数据源。 选项三：数据源为SQL语句 选【SQL语句】>【SQL编辑】>【新增】 保存更新，下拉框即可生成。 2、下拉查询框（ComboBoxSearch） 当下拉框数据较多的时候，想找到自己想选的就比较麻烦。 把字段的编辑类型有ComboBox改为ComBoxSearch,保存更新，就能实现下拉框的模糊查询。 3、多选框 勾选上【允许多选】，保存更新即可变成多选框。 4、单选/复选框（CheckBox） 字段的编辑属性选【CheckBox】,【数据源设置】跟下拉框的设置方法一样。

SelectedItem，SelectedValue和SelectedValuePath之间的区别

由 那年仲夏 提交于 2020-03-09 14:14:24
与以下内容有什么区别： SelectedItem 选定值 SelectedValuePath 所有这些依赖项属性都在 Selector 类中定义。 我经常将 SelectedItem 与 SelectedValue 以及 SelectedValue 与 SelectedValuePath 混淆。 我想知道它们之间的区别，以及我们何时使用它们，尤其是 SelectedValue 和 SelectedValuePath 。 请通过一些简单的例子说明它们的 用法 。 #1楼 每个使用Collections存储数据的控件都具有SelectedValue，SelectedItem属性。 这些控件的示例是ListBox，Dropdown，RadioButtonList，CheckBoxList。 更具体地说，如果您确实要检索“选定项目的文本”，则可以编写： ListBox1.SelectedItem.Text; 如果value之前已设置，则ListBox1也可以使用SelectedValue属性返回Text。 但是以上是获取文本的更有效方法。 现在，该值对于用户而言是不可见的，但通常用于存储在数据库中。 我们不插入ListBox1的Text，但是也可以插入它，但是我们曾经插入所选项目的值。 为了获得价值，我们可以使用 ListBox1.SelectedValue 资源 #2楼 受这个问题的启发

I would like the user to be able to keep text as "X" and only change the text to "XA" if "XA" was clicked in the drop down list. To recreate create a new WinForms application and add a comboBox then add the following
