如何使Silverlight Grid仅允许选择一个复选框. [英] How to make Silverlight Grid to allow only one Checkbox to select.

问题描述

我有一个Silverlight网格，其中有一个Checkbox列，当前用户可以选择多行.但是Silverlight网格应该只允许选中一个复选框(如果选中了另一个复选框，则应取消选中该复选框-例如Radiobutton).因此，我将从Checkbox中获取网格的行数据.

，有人可以建议如何提出上述要求.

非常感谢....

Hi,

I have a Silverlight grid, which is having a Checkbox column, currently the user can select multiple rows. But the silverlight grid should allow only one checkbox to be selected(If another selected the other should deselect - like Radiobutton). So i will get the row data of grid from Checkbox checked.

, Can anybody suggest how to make the above requriement.

Many thanks....

推荐答案

最简单的方法-在复选框数据源中运行一个循环(假设您的绑定是两种方式).

Easiest way - run a loop through the checkbox datasource (assuming your binding is two way).
Check the one selected and remove the selection on the others.

CheckBox previousCheckBox = null;
        private void chkPerson_Click(object sender, RoutedEventArgs e)
        {
            if(previousCheckBox!=null)
            {
                previousCheckBox.IsChecked = false;
            }

            CheckBox currentCheckBox = sender as CheckBox;
            previousCheckBox = currentCheckBox;
        }

        private void chkPerson_Unchecked(object sender, RoutedEventArgs e)
        {
            previousCheckBox = null;
        }
