在vb.net中动态过滤转发器列表 [英] Filter Repeater list dynamically in vb.net
问题描述
我正在使用带有3列(名称,描述,日期)的转发器控制列表。我需要根据在文本框中输入的关键字过滤列表,以便动态描述而无需回发。
当用户在文本框中输入单词并按回车键或制表键时,我能够过滤列表,但是对于这个解决方案,会发生回发。
当用户在文本框中输入任何字符时,有没有一种方法不会发生poatback并动态更新列表?

是否有一种回发不会发生的方式当用户不断输入任何字符时,列表会动态更新在文本框中?
第一点令人困惑。你根本不想要回发,或者你想要AsyncPostBack。您可以使用UpdatePanel。
对于第二点,您需要为<设置AutoPostBack
'true' code> TextBox 并处理TextChanged
事件。

I am using repeater control list with 3 columns(Name, Description, Date). I need to filter the list based on a keyword entered in a textbox for description dynamically without postback.
I am able to filter the list when user enter a word in textbox and presses enter key or tab key, but for this solution postback happens.
Is there a way that poatback does not happen and the list gets updated dynamically when user keeps typing any character in textbox?

First point is confusing. You don't want postback at all, or you want AsyncPostBack. You can use UpdatePanel.
For the second point, you need to setAutoPostBack
'true' for theTextBox
and handleTextChanged
event.
