关于developer express 的 RepositoryItemCheckEdit 多选设置

.net第三方控件developer express,竟然发现里面的模板列RepositoryItemCheckEdit默认的状态和单选钮一样,虽然我们有时候也很需要这样的功能,但是有时候我们也要有复选按钮的功能

1.将要设置的列，设一个模板列为RepositoryItemCheckEdit1

2.绑定要显示的字段，若没有可以自己构造一个空列，如：select '1' as 新列 ，T.*,from table1 T，也可设为'True'或者'Yes'，视个人情况而定

3.设置事件：repositoryItemCheckEdit1_QueryCheckStateByValue

4.代码示例如下：

4.1 //根据绑定的值显示选择状态

4.1 //根据绑定的值显示选择状态

private void repositoryItemCheckEdit1_QueryCheckStateByValue(object sender, DevExpress.XtraEditors.Controls.QueryCheckStateByValueEventArgs e)
        {
            string val = "";
            if (e.Value != null)
            {
                val = e.Value.ToString();
            }
            else
            {
                val = "False";//默认为不选
            }
            switch (val)
            {
                case "True":
                case "Yes":
                case "1":
                    e.CheckState = CheckState.Checked;
                    break;
                case "False":
                case "No":
                case "0":
                    e.CheckState = CheckState.Unchecked;
                    break;
                default:
                    e.CheckState = CheckState.Checked;
                    break;
            }
            e.Handled = true;
        }

private void repositoryItemCheckEdit1_QueryCheckStateByValue(object sender, DevExpress.XtraEditors.Controls.QueryCheckStateByValueEventArgs e)
        {
            string val = "";
            if (e.Value != null)
            {
                val = e.Value.ToString();
            }
            else
            {
                val = "False";//默认为不选 
            }
            switch (val)
            {
                case "True":
                case "Yes":
                case "1":
                    e.CheckState = CheckState.Checked;
                    break;
                case "False":
                case "No":
                case "0":
                    e.CheckState = CheckState.Unchecked;
                    break;
                default:
                    e.CheckState = CheckState.Checked;
                    break;
            }
            e.Handled = true;
        }

4.2 //由选择状态改变绑定列的值
        private void repositoryItemCheckEdit1_QueryValueByCheckState(object sender, DevExpress.XtraEditors.Controls.QueryValueByCheckStateEventArgs e)
        {
            if (e.CheckState == CheckState.Checked)
            {
                gridView1.SetRowCellValue(gridView1.FocusedRowHandle, "绑定列", 1);
            }
            else
            {
                gridView1.SetRowCellValue(gridView1.FocusedRowHandle, "绑定列", 0);
            }
        }
