问题描述
我正在创建一个包含3个图表和一个网格的仪表板。
所有图表和网格都放在单独的UpdatePanel中，并且是从单独的C＃方法绑定的，这些方法都在Page_LoadComplete中调用（ ）。
问题：在点击GridView的页面索引时，所有控件都会获得Postback以及各自的UpdatePanel。我不想要这个。
我只想要那个控件必须回发我想要的，就像我点击网格的页面索引一样那个网格回发不是所有的控件。
这是我的HTML（.aspx）代码：
I''m creating a Dashboard with 3 Charts and a Grids.
All the charts and grids are placed in separate UpdatePanel and are binding from separate C# methods which all are getting called in Page_LoadComplete().
Problem: On clicking the page index of GridView, all the controls are getting Postback withing their respective UpdatePanels. I don''t want this.
I want only that control must postback which i want, As like, if i click the grid''s page index, only that grid postback not all the controls.
This is my HTML(.aspx) Code:
<div class="col-md-12">

Set Update mode of update panel as conditional like UpdateMode=\"Conditional\"
And each event set is UpdatePanel1.Update();
as per yours condition.
