在网格视图中显示下拉列表值 [英] to display dropdown lists value in grid view

问题描述

我是asp.net的新手.
我在上方选择了一个下拉列表，在下方选择了gridview.
如果我在客户ID的下拉列表中选择特定值，则应在gridview中显示客户详细信息.
请尽快帮助我.

推荐答案

确保在aspx中将DropDownList的AutoPostBack属性设置为True

make sure you set AutoPostBack Property of DropDownList to True in aspx

<asp:dropdownlist id="ddlCompany" runat="server" onselectedindexchanged="ddlCompany_SelectedIndexChanged" autopostback="true" xmlns:asp="#unknown" /> 

以下是您背后的代码中的事件处理程序

the below is your event handler in code behind

protected void ddlCompany_SelectedIndexChanged(object sender, EventArgs e)
{
   string strCompID = ddlCompany.SelectedValue.ToString();
   //bind here your GridView's data bsed on the selected ID strCompID.
}
