  对复选框所做的所有选择

您必须保持的Page_Load 在 Page.IsPostback 是价值假像下面时..

 保护无效的Page_Load（对象发件人，EventArgs的发送）
{
    如果（！Page.IsPostBack）
    {
        //你的code
    }
}
 

这不会造成松动您点击按钮后做出格复选框选择。

您的GridView的EnableViewState必须为True

您模板字段必须在设计师页

I would like to disable postback on a onClick event of a button.

I did some research online and most are using onClientClick and using javascript. Is there a way to call a asp.net function "btnCommit_Click" on the onClick instead of using onclientclick and using javascript?

If not, how would I be able to incorporate a asp.net function with javascript?

<asp:Button ID="btnCommit" runat="server" Text="Save" TabIndex="5" 
    onclick="btnCommit_Click" />

UPDATED I have a GridView which contains checkboxes, once the user makes their changes and click on a "Save Button" a Post Back occurs and I loose all the selections made to the checkboxes I was thinking of disabling the postback on the OnClick Event of the button would solve that issue...

You have to keep the Page_Load under Page.IsPostback during is's value to false like below..

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        //Your code
    }
}

This will not cause to loose you grid checkbox selection made after clicking the button.

Your GridView EnableViewState must be True

Your template fields must be in designer page
