如何使用数组绑定下拉列表 [英] How to Bind a dropdown using Array

问题描述

我有问题.我想使用字符串数组绑定一个下拉列表.我正在使用从另一个页面调用的会话.会话现在工作正常，问题是当我绑定下拉列表时抛出错误..

I have a problem. I want to bind a dropdown using a string array. I am using a session which is called from another page. Session is working fine now the problem is when I bind the dropdown it throw an error..

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Name'

if (Session["Driver"] != null)
{
    string[] arr_list = (string[])Session["Driver"];
    DDDriver.DataSource = arr_list;
    DDDriver.DataBind();  //<b>Error here.....</b>
    DDDriver.Items.Add("select");
    DDDriver.SelectedItem.Text = "select";
}

错误:System.String'' does not contain a property with the name ''Driver_Name''.

推荐答案

您正在将下拉菜单DataTextField的DataValueField的这些属性之一设置为"Driver_Name".删除此错误也应清除错误.

You are setting one of these properties on the drop down DataTextField, DataValueField to ''Driver_Name''. removing this should clear the error as well.

string[] a = new string[] {"Arun","vinay","Manju","Pavan" };
        DropDownList1.DataSource = a.ToArray();
        DropDownList1.DataBind();
