WebCombo 添加自定义下拉列表

    不太会用NetAdvantage这个控件，昨天折腾了半天。本来以为会像Asp.net里的DropDownList一样，结果发现在属性里添加Columns，再在Rows里添加没效果，后来查到网上有人将Hashtable与DropwDownList绑定，在WebCombo上也不行，只好用内存表方式，照着例子将DataSource和DataMember设置为内存表的DataSet和表名，还是不行，真是奇怪啊，后来看到UltraWebGrid里将DataSource直接绑定到表，试着在WebCombo上用了一下，可以了。

protected Infragistics.WebUI.WebCombo.WebCombo ConditionCB;

        private void SetConditionCB()
        {
            DataSet dsCondition=new DataSet("dsCondition");
            DataTable tData=new DataTable("tData");

            DataColumn cName=new DataColumn("条件");
            tData.Columns.Add(cName);

            DataRow RowData;
            RowData=tData.NewRow();
            RowData["条件"]="等于";
            tData.Rows.Add(RowData);

            RowData=tData.NewRow();
            RowData["条件"]="包含";
            tData.Rows.Add(RowData);

            RowData=tData.NewRow();
            RowData["条件"]="匹配开头";
            tData.Rows.Add(RowData);

            RowData=tData.NewRow();
            RowData["条件"]="不等于";
            tData.Rows.Add(RowData);

            RowData=tData.NewRow();
            RowData["条件"]="大于";
            tData.Rows.Add(RowData);

            RowData=tData.NewRow();
            RowData["条件"]="大于或等于";
            tData.Rows.Add(RowData);

            RowData=tData.NewRow();
            RowData["条件"]="小于";
            tData.Rows.Add(RowData);

            RowData=tData.NewRow();
            RowData["条件"]="小于或等于";
            tData.Rows.Add(RowData);
            
            dsCondition.Tables.Add(tData);
            
            //ConditionCB.DataSource=dsCondition;
            ConditionCB.DataSource=dsCondition.Tables[0];
            //ConditionCB.DataMember="tData";
            ConditionCB.DataBind();
