我每次點擊一個按鈕時會如何阻止我的頁面重新加載？

Question

這是當我搜索一些東西后點擊我的gridview時發生的情況，然後我的下一個命令是從gridview獲取數據到文本框來編輯文件並再次保存，但是select命令不工作，因爲它應該是..因爲gridview正在重新加載，我過濾的文件不見了，它會選擇gridview中的第一行，我該怎麼辦？這裏是我選擇命令的代碼

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; 
    } 
} 

我應該使用IsPostBack還是viewstate？我將如何設置它或代碼？

這裏是我的gridview的

Answer 1

你需要用在AJAX UpdatePanel您就地更新控制代碼。

這應該表示當這些特定控件更新時，您的頁面將不會重新加載。

Answer 2

您需要刪除網格命令onselectedindexchanged =「GridView1_SelectedIndexChanged」或onselectedindexchanging =「GridView1_SelectedIndexChanging」之一。
