Windows Mobile 中ComboBox【下拉列表】的使用

 

【1】使用xml数据源绑定数据

         /// <summary>
        /// 从MiddleCateGoryName.xml文件中读出数据添加到(中类别)下拉框中
        /// </summary>
        private void ReadMiddleCategoryXml()
        {
            DataTable dt = new DataTable();
            DataSet ds = new DataSet();
            if (File.Exists(strConfigFileUrl + "MiddleCateGoryName.xml"))
            {
                ds.ReadXml(strConfigFileUrl + "MiddleCateGoryName.xml");
                if (ds.Tables.Count < 1)
                {
                    return;
                }
                dt = ds.Tables[0];
                cbxMiddleCategory.Items.Clear();
                foreach (DataRow dr in dt.Rows)
                {
                    cbxMiddleCategory.Items.Add(dr["rightName"].ToString());

                }
            }

        }

 

【2】双击 该控件，获取该选择事件；
        private void cbxMiddleCategory_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (cbxMiddleCategory.Items[Convert.ToInt32(cbxMiddleCategory.SelectedIndex)].ToString() != null)
            {
                string strCategoryName = cbxMiddleCategory.Items[Convert.ToInt32(cbxMiddleCategory.SelectedIndex)].ToString(); //获取选择的值

             }
        }
