我的问题是我有一个asp文本框,它有一个值(文本)但是被禁用(Enabled =“false”)
点击(编辑)按钮后,它变为启用状态(启用=“真”),这样我就可以更改文字了
- >更改文本并单击(保存)按钮后,它之前采用旧值(文本) 编辑并保存而不是新的 ..
ReadOnly 属性也会出现此问题。
我被困在这......所以任何帮助我都会感激不尽。

以下是 C#代码(没有必要编写SQL连接):
protected void Page_Load(object sender, EventArgs e)
{
Email.Text = myDataTable.Rows[0][2].ToString();
Email.DataBind();
Email.Enabled = false;
}
protected void Enable_Info(object sender, EventArgs e)
{
if (UpdateButton.Text == "تـعــديـل")
{
Email.Enabled = true;
UpdateButton.Text = "حــفـظ";
CancelButton.Visible = true;
}
else if (UpdateButton.Text == "حــفـظ")
{
AjaxPanel1.EnableAJAX = false;
int CustomerId = System.Convert.ToInt32(Request.Cookies["User"]["CustomerId"]);
string email = Email.Text;
SqlConnection conn = new SqlConnection(ArabShoppingConfiguration.DbConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
cmd.CommandText = "update Customer set Email = '" + email + "' where Id = '" + CustomerId + "'";
try
{
conn.Open();
cmd.ExecuteScalar();
}
catch (Exception ex)
{
throw ex;
}
finally
{
conn.Close();
}
}
}
protected void Cancel_Info(object sender, EventArgs e)
{
Email.Enabled = false;
UpdateButton.Text = "تـعــديـل";
CancelButton.Visible = false;
}
答案 0 :(得分:4)
好的,问题是您在页面加载中设置了Email.Text,每次加载页面时都会运行,以包含所有回发。页面加载在Enable_Info方法之前触发,因此每次都会更改文本。您需要做的就是修改page_load代码,使其仅在页面加载时运行,而不是在回发时运行:
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
Email.Text = myDataTable.Rows[0][2].ToString();
Email.DataBind();
Email.Enabled = false;
}
}
