<asp:Button ID="btnSaveBankInformation" runat="server" Text="<%$Resources:Strings,save%>"
            OnClick="btnSaveBankInformation_Click" />

protected void btnSaveBankInformation_Click(object sender, EventArgs e)
{
TextBox txtBankAccountNumber = bankAccounts_List.Rows[i].Cells[GetColumnIndexByName(bankAccounts_List.Rows[i], "Account Number")].FindControl("grd_txtbankAccountNumber") as TextBox;
}

我在任何文本框中更改了什么，在保存按钮上我总是得到旧的绑定文本框值而不是我刚刚输入的新值。请帮助我。是的，我没有使用!IsPostBack

再次在PostBack上绑定GridView

Answer 1

if (!IsPostBack) //Bind grid only when IsPostBack is false
{
    grd.DataSource = //data source ;
    grd.DataBind(); // bind data 
}

asp：gridview文本框旧值回发
