我的网络表单上有4 ajaxToolkit:ComboBox。在页面加载事件中，我已填充所有4 combo-boxes。但我的页面只显示了一个combo-box和3个text-boxes。

Aspx页码

服务器端代码

protected void Page_Load(object sender, EventArgs e)
{
    DataSet ds = new DataSet();
    string ServerID = ddlServer.SelectedValue;
    ds = clsTransaction.Select(@"SELECT wsid AS ID,nm AS Name FROM tblwser ORDER BY nm;
SELECT acid AS ID,nm AS Name FROM tblReseller WHERE wsid = '" + ServerID + @"' ORDER BY nm;
SELECT acid AS ID,nm AS Name FROM tblReseller WHERE wsid = '" + ServerID + @"' ORDER BY nm;
SELECT destid AS ID,destname AS Name FROM tbldestination WHERE wsid = '" + ServerID + "' ORDER BY destname",
            DataSendBSSWEB.ServerDbEnum.MainSqlServer,
            false);
    ddlServer.DataSource = ds.Tables[0];
    ddlServer.DataTextField = ds.Tables[0].Columns[1].ColumnName;
    ddlServer.DataValueField = ds.Tables[0].Columns[0].ColumnName;
    ddlServer.DataBind();
    ddlOrg.DataSource = ds.Tables[1];
    ddlOrg.DataTextField = ds.Tables[1].Columns[1].ColumnName;
    ddlOrg.DataValueField = ds.Tables[1].Columns[0].ColumnName;
    ddlOrg.DataBind();
    ddlTer.DataSource = ds.Tables[2];
    ddlTer.DataTextField = ds.Tables[2].Columns[1].ColumnName;
    ddlTer.DataValueField = ds.Tables[2].Columns[0].ColumnName;
    ddlTer.DataBind();
    ddlDest.DataSource = ds.Tables[3];
    ddlDest.DataTextField = ds.Tables[3].Columns[1].ColumnName;
    ddlDest.DataValueField = ds.Tables[3].Columns[0].ColumnName;
    ddlDest.DataBind();
    functionclass.SetFocus(ddlServer);
}

This is result of my code

任何人都可以告诉我这是什么问题，我该如何解决这个问题。
