树形结构treeview 前端代码：
<form id="form1" runat="server">
<div>
<asp:TreeView ID="TreeView1" runat="server">
</asp:TreeView>
</div>
</form>
后端代码：
public partial class ChannelList : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
CreateTreeVeiw();
}
}
DataSet ds;
DataTable dt;
private void CreateTreeVeiw()
{
ds = SqlComm.GetDataByCondition("BioErpCrmManageChannel", "ChannelID,SuperiorChannel,ChannelName", "1=1");
dt = new DataTable();
dt = ds.Tables[0];
DataView dv = new DataView(dt, "SuperiorChannel=0 or SuperiorChannel=null", "ChannelID", DataViewRowState.CurrentRows);
//遍历父节点
foreach (DataRowView d in dv)
{
TreeNode n = new TreeNode(d["ChannelName"].ToString(), d["ChannelID"].ToString());
n.ImageToolTip = dt.TableName;
TreeView1.Nodes.Add(n);
n.Expanded = false;
//根据父节点筛选出对应的子节点
dv = new DataView(dt, "SuperiorChannel='" + d["ChannelID"] + "'", "ChannelID", DataViewRowState.CurrentRows);
if (dv.Count > 0)
{
CreateSubTreeView(n, dv);
}
}
}
/// <summary>
/// 添加子项
/// </summary>
/// <param name="n"></param>
/// <param name="dv"></param>
private void CreateSubTreeView(TreeNode n, DataView dv)
{
foreach (DataRowView d in dv)
{
TreeNode cn = new TreeNode(d["ChannelName"].ToString(), d["ChannelID"].ToString());
n.ChildNodes.Add(cn);
DataView sdv = new DataView(dt, "SuperiorChannel='" + d["ChannelID"] + "'", "ChannelID", DataViewRowState.CurrentRows);
if (sdv.Count > 0)
{
CreateSubTreeView(cn, sdv);
}
}
}
}
js代码：
function showChannel() {
var re = showModalDialog("../PersonList/ChannelList.aspx", "", "dialogWidth=350px;dialogHeight=400px");
}前端加载页面：
<td>上级渠道</td><td><asp:TextBox ID="txtJuridicalPerson" runat="server"></asp:TextBox>
<input type="button" onclick="showChannel()" value="选择"/>
</td>
显示页面的界面前端代码：
<script type="text/javascript">
function ReturnValue(noteid) {
if (noteid != NaN || noteid != 0) {
window.returnValue = noteid;
window.close();
} else {
window.returnValue = 0;
window.close();
}
}
</script>
js代码：
function showChannel() {
var re = showModalDialog("../../PersonList/ChannelList.aspx", "", "dialogWidth=350px;dialogHeight=400px");
txtSuperChannelID = document.getElementById("txtSuperChannelID")
if (re != null) {
if (txtSuperChannelID != null) {
txtSuperChannelID.value = re;
} else {
txtSuperChannelID.value = "0";
}
} else {
txtSuperChannelID.value = "0";
}
