我有一个GridExtension
看起来像这样的 MVC:
它从中获取数据的表如下所示:
表名:类别
Id Name
--------------
1 Foo
2 Bar
3 Gar
4 Har
当我从网格中选择一行或多行并单击顶部的删除按钮时,我希望我的DeleteSelectedCategories
处理程序应该被调用,这确实发生了。
但是,在DeleteSelectedcategories
处理程序中,当我调用gvCategories.GetSelectedFieldValues
为其提供客户端回调的方法时DeleteCategories
,该方法不会被调用。相反,我将所有脚本代码显示在消息框中,如下所示:
我使用的代码与 DevExpress 文档网站上此示例中显示的代码几乎相同。
这是我的代码。
看法
<script type = "text/javascript">
//<![CDATA[
$(document).ready(
function () {
WireHandlers();
}
);
function DeleteCategories(selectedCategoriesArray) {
debugger;
if (selectedCategoriesArray.length == 0) return;
for (var i = 0; i < selectedCategoriesArray.length; i++) {
debugger;
}
}
function DeleteSelectedCategories() {
// debugger;
if (gvCategories.GetSelectedRowCount() == 0) return;
gvCategories.GetSelectedFieldValues('Id', DeleteCategories);
}
function WireHandlers() {
$('#btnDeleteCategory').click(DeleteSelectedCategories);
}
// ]]>
</script>
