在selectedindexchange上显示消息 [英] show message on selectedindexchange

问题描述

嗨


i有一个Listview和DataPager。

我也有复选框onselectedindexchange，我在其中过滤数据表..并在listview中显示。 />


所以对于exp，我在listview中有100条记录，在DataPager1_PreRender和page_load中，我这样做



< pre lang =cs> ProductList.DataSource = datatablename;
ProductList.DataBind（）;

当调用复选框事件（onselectedindexchange）时，我过滤数据表并显示50条记录（对于exp）..所以在listview中我现在显示50条记录。



因此，当对记录进行过滤时，我想显示工作正在进行的用户消息



和酒店的makemytrip过滤一样。



如何做到这一点

Hi
i have a Listview and DataPager.
also i have checkbox onselectedindexchange in which i filter a datatable..and display in listview.

so for exp, i have 100 records in listview, in DataPager1_PreRender and page_load , i do as

ProductList.DataSource = datatablename;
ProductList.DataBind();

and when checkbox event (onselectedindexchange) called, i filter datatable and show 50 records (for exp) .. so in listview i show now 50 records.

So when filtering for records is going on , i want to show user message that work is going on

same like makemytrip filtering for hotels.
