Coolite学习笔记----ComBoBox绑定数据源

绑定方式1：

private void BindCombox2(ComboBox cb)
{
DataTable dt = new Bll.CoolingWater().GetAllCoolingWater();

foreach (DataRow r in dt.Rows)
{
cb.Items.Add(new Coolite.Ext.Web.ListItem(r[1].ToString(),r[0].ToString()));
}
}

绑定方式2：

<ext:Store ID="StoreInfo" runat="server" AutoLoad="true"
OnRefreshData="InitComboBox">
<Reader>
<ext:JsonReader ReaderID="COOLING_WATER_ID">
<Fields>
<ext:RecordField Name="COOLING_WATER_ID">
</ext:RecordField>
<ext:RecordField Name="COOLING_WATER_NAME">
</ext:RecordField>
</Fields>
</ext:JsonReader>
</Reader>
</ext:Store>
<ext:ComboBox ID="Cbo" runat="server" AllowBlank="true"
StoreID="StoreInfo" ValueField="COOLING_WATER_ID"
DisplayField="COOLING_WATER_NAME" TriggerAction="All" EmptyText="-请选择-" ReadOnly="true" Width="100px">
</ext:ComboBox>

public void InitComboBox(object sender, StoreRefreshDataEventArgs e)
{
Bll.CoolingWater bo = new Bll.CoolingWater();
StoreInfo.DataSource = bo.GetAllCoolingWater();
StoreInfo.DataBind();
}
