如何在多个Dropdownlist中显示相同的列字段 [英] How to display same column fields in multiple Dropdownlist

问题描述

所有

 strQry =  从ShiftLite中选择CodeC; 
 DataTable dt2 =  new  DataTable（）; 
 dt2 = DbCon.GetData（strQry）; 
 DropDownList1.DataSource = dt2; 
 DropDownList1.DataTextField =   CodeC; 
 DropDownList1.DataBind（）; 
 DropDownList1.Items.Insert（ 0 ， new  ListItem（   -  SELECT  - ， ））; 
 

这里我想要从数据库中检索的相同字段我想显示多个DropDlist如DropDownList2，DropDownList3，DropDownList4，DropDownList5



有没有办法轻松搞定



谢谢你！

解决方案

用4个args创建一个函数

 PopulateDropDown（DropDownList ddl，DataTable dt， string  displayField， string  defaultText）{
 ddl.DataSource = dt; 
 ddl.DataTextField = displayField; 
 ddl.DataBind（）; 
 DropDownList1.Items.Insert（ 0 ， new  ListItem（DefaultText， ））; 
} 

我相信这个问题在这里得到解答。

解决方案

Create one function with 4 args

PopulateDropDown(DropDownList ddl,DataTable dt,string displayField,string defaultText){
            ddl.DataSource = dt;
            ddl.DataTextField = displayField;
            ddl.DataBind();
            DropDownList1.Items.Insert(0,new ListItem(DefaultText,""));
}

I believe this question is answered here.
