Hi, i want to ask why OnEntryAdded on RadDropDownTree is not working. I have a RadDropDownTree and RadHTMLChart

The scenario is when i pick one of the nodes, get the value, set it on RadHTMLChart, and render it using AJAX

This is piece of the code:

<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RDDTreeTeam">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="ProgressChart" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" Skin="Silk"></telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<div>

<table width="100%" border="1">

<tr>

<td rowspan="2" valign="top">

<telerik:RadDropDownTree ID="RDDTreeTeam" runat="server" Width="250" EnableFiltering="true"

DataFieldID="ID" DataFieldParentID="ParentID" DataTextField="Text" DataValueField="Value"

Skin="Silk" OnEntryAdded="RDDTreeTeam_EntryAdded" OnClientDropDownClosing="OnClientDropDownClosing">

<DropDownSettings Height="200" OpenDropDownOnLoad="true" CloseDropDownOnSelection="false"/>

<ButtonSettings ShowClear="true" />

<FilterSettings Highlight="Matches" EmptyMessage="Type here" />

</telerik:RadDropDownTree>

</td>

<td class="style1" align="center">

<telerik:RadHtmlChart runat="server" ID="ProgessChart" Width="300px"

Height="300px" Transitions="true" Skin="Silk">

<ChartTitle Text="Progress Sales">

<Appearance Align="Center" Position="Top">

</Appearance>

</ChartTitle>

<Legend>

<Appearance Position="Bottom" Visible="true">

</Appearance>

</Legend>

<PlotArea>

<Series>

<telerik:PieSeries StartAngle="90" DataFieldY="ProgressAmount" NameField="ProgressType">

<LabelsAppearance Position="OutsideEnd" DataFormatString="{0}">

</LabelsAppearance>

<TooltipsAppearance Color="White" DataFormatString="{0}"></TooltipsAppearance>

</telerik:PieSeries>

</Series>

</PlotArea>

</telerik:RadHtmlChart>

</td>

</tr>

</table>

</div>

</telerik:RadAjaxPanel>

protected void RDDTreeTeam_EntryAdded(object sender, DropDownTreeEntryEventArgs e)

{

if (e.Entry.Value == "1")

{

DataTable dtPie = new DataTable();

dtPie.Columns.Add(new DataColumn("ProgressAmount"));

dtPie.Columns.Add(new DataColumn("ProgressType"));

dtPie.Columns.Add(new DataColumn("Color"));

dtPie.Columns.Add(new DataColumn("IsExploded"));

dtPie.Rows.Add(new object[] { 803, "On Progress", "Red", false });

dtPie.Rows.Add(new object[] { 464, "Close Selling", "Green", false });

dtPie.Rows.Add(new object[] { 505, "Rejected", "Blue", false });

dtPie.Rows.Add(new object[] { 201, "Not Yet Follow Up", "Yellow", false });

ProgessChart.DataSource = dtPie;

ProgessChart.DataBind();

}

else if (e.Entry.Value == "2")

{

DataTable dtPie = new DataTable();

dtPie.Columns.Add(new DataColumn("ProgressAmount"));

dtPie.Columns.Add(new DataColumn("ProgressType"));

dtPie.Columns.Add(new DataColumn("Color"));

dtPie.Columns.Add(new DataColumn("IsExploded"));

dtPie.Rows.Add(new object[] { 203, "On Progress", "Red", false });

dtPie.Rows.Add(new object[] { 464, "Close Selling", "Green", false });

dtPie.Rows.Add(new object[] { 805, "Rejected", "Blue", false });

dtPie.Rows.Add(new object[] { 401, "Not Yet Follow Up", "Yellow", false });

ProgessChart.DataSource = dtPie;

ProgessChart.DataBind();

}

But, when i click on the node, there's nothing happened.

Please help me.

Thank you in advance
