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();
/*
Hashtable condition=new Hashtable();
condition.Add("等于","等于");
condition.Add("包含","包含");
condition.Add("不包含","不包含");
condition.Add("匹配开头","匹配开头");
condition.Add("不匹配开头","不匹配开头");
condition.Add("匹配结尾","匹配结尾");
condition.Add("不匹配结尾","不匹配结尾");
condition.Add("不等于","不等于");
condition.Add("大于","大于");
condition.Add("大于或等于","大于或等于");
condition.Add("小于","小于");
condition.Add("小于或等于","小于或等于");
condition.Add("空","空");
condition.Add("非空","非空");
//ConditionCB.Columns.Add("","查询条件");
ConditionCB.DataSource=condition;
//ConditionCB.DataMember="";
ConditionCB.DataValueField="Key";
ConditionCB.DataTextField="Value";
ConditionCB.DataBind();
