WebCombo是Intersoft公司推出的一款功能强大的下拉列表框控件，该控件支持多种数据源绑定，支持客户端数据绑定，支持数据的懒加载，并且可以通过设计时设计和运行时代码操作，并且该控件还可以和WebTreeView以及WebContextMenu进行整合。这篇文章主要介绍在非绑定模式下如何使用代码在客户端为WebCombo添加数据，下面是具体的代码：

function addItem()

{

   var wc4 = ISGetObject("WebCombo1");

   var rows = wc4.GetRows(); // get the WebCombo4's rows for addition

   var newRow = wc4.NewRow("NEWCUST2"); // instantiate new row with NEWCUST as the KeyValue, containing cells with empty value

   var cells = newRow.GetCells(); // get the cells of the new row for value assignment

                                 

   // addition

   cells.GetNamedItem("ContactName").Text = "New Customer2"; // write codes in the same way as in server-side object model, with 

 

similar object hierarchy.

   cells.GetNamedItem("Address").Text = "New Address2"; // assign value to Address Cell

   cells.GetNamedItem("CustomerID").Text = "NEWCUST2";

   rows.Add(newRow); //add the newRow to the rows collection

 

   // modification

   cells = rows[1].GetCells();

   cells[0].Text = "Changed Text"; // modify the text

   rows[1].SetChanged();

                                 

   // update all changes now

   wc4.UpdateUI();

}

<input id="Button1" type="button" value="Test" onclick="addItem()" />
