使用场景:数字范围控件使用滑块来控制起始值和截止值,以此来输入一个数字范围来进行数据过滤。需绑定两个整型的参数或两个浮点型的参数。
使用示例:
1. 定义两个类型相同的报表参数,可以都为整型或者都为浮点型。比如:
2. 进入查询面板,单击添加一个数字范围控件。
3. 绑定参数。
有两种方法可以绑定参数。
方法一:单击控件旁的红色按钮,下拉窗口中将显示可用的参数,单击需要的参数即可完成绑定。请注意先单击作为起始值的参数,再单击作为截止值得参数。
方法二:在属性设置中进行绑定。
4. 外观与属性设置。
鼠标拖动可改变控件的大小和位置。
在右侧的属性设置面板中可对控件进行外观显示和属性设置。
比如我们将标题文本改为“拖动滑块选择数字范围”。
