{
    FileUpload newfileuploadcontrol = (FileUpload)FormView1.FindControl("FileUpload1") as FileUpload;
    TextBox newtextbox = (TextBox)FormView1.FindControl("TextBox10") as TextBox;
    if (newfileuploadcontrol.HasFile)

        TextBox newtextbox = (TextBox)FormView1.FindControl("TextBox10") as TextBox;
        if (newfileuploadcontrol.HasFile)
        {
           newfileuploadcontrol.SaveAs(Server.MapPath("/Cars/Copy_of_Payment_Images/") + newfileuploadcontrol.FileName);
           newtextbox.Text = "/Cars/Copy_of_Payment_Images/" + newfileuploadcontrol.FileName;
        }
}

推荐答案

您可以尝试下面的代码 -



如果您使用AS运算符，则无需在查找控件时使用显式转换。

Could you try with below piece of code -

If you are using "AS" operator you dont need to user explicit casting while finding control.

FileUpload newfileuploadcontrol = FormView1.FindControl("FileUpload1") as FileUpload;
TextBox newtextbox = FormView1.FindControl("TextBox10") as TextBox;
           
if (newfileuploadcontrol.HasFile)
{
    string path = Server.MapPath("/Cars/Copy_of_Payment_Images/") + newfileuploadcontrol.FileName;
    newfileuploadcontrol.SaveAs(path);
    
    newtextbox.Text = path;
}
