asp.net 基础知识

1、 DropDownList 的赋值

Response.Write(DropDownList1.Items.FindByText("潍坊").Value);
Response.Write(DropDownList1.Items.FindByValue("0536").Text);

Response.Write(DropDownList1.SelectedItem.Value);

2、GridView 模板列取值

' runat="server" Text='<%#DotNet.Common.StringHelper.CutString(DataBinder.Eval(Container.DataItem, "examroom_name").ToString(),16,true)%>'>

protected void Button1_Click(object sender, EventArgs e)

{

for (int i=0; i< GVListShow.Rows.Count; i++)

{

((Label)GVListShow.Rows[i].FindControl("Labpexamroom_name")).Text = "44445";

}

}
