如何绑定下拉列表 [英] How to bind dropdown list

问题描述

 DataTable dtCurrentTable = new DataTable
for (int i = 0; i < dtCurrentTable.Rows.Count; i++)
 {
    DropDownList ddltype =
    (DropDownList)gvFormula.Rows[rowIndex].Cells[1].FindControl("ddltype");


     ddlproduct.SelectedItem.Text = dtCurrentTable.Rows[i]["ddltype"].ToString();
     rowIndex++;
 }

当我分配下拉列表值时。它只显示一个值。

我的要求是在选择时绑定下拉列表中的所有值

When I assign dropdown list value . Its showing only one value.
My requirement is to bind all the values in dropdown list when selected

推荐答案

DataSet ds = new DataSet();
     SqlDataAdapter da = new SqlDataAdapter("Select distinct(name)from employee", connection);
     da.Fill(ds);
     drpemployee.DataSource = ds;
     drpemployee.DataValueField = "name";
     drpemployee.DataBind();
     drpemployee.Items.Insert(0, "--Select--");
