推荐答案

无法在dropdownlist中绑定两列...尝试在数据库端结合两个列值并对其进行绑定.

例如SELECT(efname +-" + elname)from employeemaster.

There is no way to bind two column in dropdownlist... try to combine two column values at database side and bind it.

e.g. SELECT (efname + " - " + elname) as ename from employeemaster..

DropDownList1.DataSource = ddDR;
DropDownList1.DataTextField = "DisplayValueFieldFromDB";
DropDownList1.DataValueField = "DataValueFieldFromDB";
DropDownList1.DataBind();

ddDR是数据源

ddDR is DataSource
