嗨Frnds，我是priya。我正在努力让我的头围绕raddropdowntree。

我使用c＃在我的asp.net网络应用程序中使用它。



i在aspx文件中添加了以下代码



<％@ Register Assembly =Telerik.Web .UINamespace =Telerik.Web.UITagPrefix =telerik％>



和



< telerik：RadScriptManager ID =RadScriptManager1runat =server>

< telerik：RadDropDownTree runat =serverID =RadDocumentSkin =TelerikWidth = 250px

DefaultMessage =选择文档DefaultValue =0DataFieldID =IDDataFieldParentID =ParentIDDataTextField =Text>

< dropdownsettings height =140px>






aspx.cs文件中的




public DataTable GetData（）

{

DataSet ds = new DataSet（）;

DataTable table = new DataTable（）;

table.Columns.Add（ID）;

table.Columns.Add（ParentID）;

table.Columns.Add（Value）;

table.Columns.Add（Text）;

table.Rows.Add（new String [] {1，null，Africa}）;

table.Rows.Add（new String [] {2，1，Egypt}）;

table.Rows.Add（new String [] {3，2，Cairo}）;

table.Rows.Add（new String [] {4，1，South Africa}）;

table.Rows.Add（new String [] {5，4，Cape Town}）;

返回表格;

}



i附加数据到raddropdowntree

protected void Page_Load（object sender，EventArgs e）

{

RadDocument.DataSource = GetData（）;

RadDocument.DataBind（）;

RadDocument.ExpandAllDropDownNodes（）;

}





但是当我运行应用程序时，它会单独显示控件并选择选择文档文本。当我点击它时它不会下降。请帮助我。

Hi Frnds, I am priya. i am struggling to get my head around raddropdowntree.
i used this in my asp.net web app using c#.

i added the following code
in aspx file
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

and

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
<telerik:RadDropDownTree runat="server" ID="RadDocument" Skin="Telerik" Width="250px"
DefaultMessage ="Choose a document" DefaultValue="0" DataFieldID="ID" DataFieldParentID="ParentID" DataTextField="Text">
<dropdownsettings height="140px">



in aspx.cs file

public DataTable GetData()
{
DataSet ds = new DataSet();
DataTable table = new DataTable();
table.Columns.Add("ID");
table.Columns.Add("ParentID");
table.Columns.Add("Value");
table.Columns.Add("Text");
table.Rows.Add(new String[] { "1", null, "Africa" });
table.Rows.Add(new String[] { "2", "1", "Egypt" });
table.Rows.Add(new String[] { "3", "2", "Cairo" });
table.Rows.Add(new String[] { "4", "1", "South Africa" });
table.Rows.Add(new String[] { "5", "4", "Cape Town" });
return table;
}
