【问题描述】：
我想通过单击在 gridview 中编辑记录。我的 gridview 放置在更新面板内。 给出了一个搜索文本框，当我在搜索文本框中输入任何内容时，“txt_Search_TextChanged”事件被触发，该文本在数据库中被搜索，该特定记录被获取并绑定到网格。
现在我的问题是：如果我单击网格的编辑按钮而不进行搜索，则会触发事件。但是，如果我搜索任何记录，然后单击编辑按钮，则需要单击 2 次才能给出结果。我为文本框编写了一个脚本，如下所示：
enter code here
<script>
function RefreshUpdatePanel() {
__doPostBack('<%= txt_Search.ClientID %>', '');
};
下面是aspx代码
