我每次点击一个按钮时会如何阻止我的页面重新加载？

Question

这是当我搜索一些东西后点击我的gridview时发生的情况，然后我的下一个命令是从gridview获取数据到文本框来编辑文件并再次保存，但是select命令不工作，因为它应该是..因为gridview正在重新加载，我过滤的文件不见了，它会选择gridview中的第一行，我该怎么办？这里是我选择命令的代码

void getValue() 
{ 
    // GridView1.SelectedIndex = isa; 
    //gridview1Connection(); 

    GridViewRow row = GridView1.SelectedRow; 
    T_firstname.Text = (row.FindControl("lbl_Firstname") as Label).Text; 
    T_middlename.Text = (row.FindControl("lbl_Middlename") as Label).Text; 
    T_lastname.Text = (row.FindControl("lbl_Lastname") as Label).Text; 
    T_age.Text = (row.FindControl("lbl_Age") as Label).Text; 
    T_id.Text = (row.FindControl("lbl_ID") as Label).Text; 
    string gender = (row.FindControl("lbl_Sex") as Label).Text; 

    if (gender == "FEMALE") 
    { 
     female_b.Checked = true; 
     male_b.Checked = false; 
    } 
    else 
    { 
     male_b.Checked = true; 
     female_b.Checked = false; 
    } 
} 

我应该使用IsPostBack还是viewstate？我将如何设置它或代码？

这里是我的gridview的

Answer 1

你需要用在AJAX UpdatePanel您就地更新控制代码。

这应该表示当这些特定控件更新时，您的页面将不会重新加载。

Answer 2

您需要删除网格命令onselectedindexchanged =“GridView1_SelectedIndexChanged”或onselectedindexchanging =“GridView1_SelectedIndexChanging”之一。
