[Solved] Radtreeview Performance

[Suresh Balan]

Hi Sir,

I use RadTreeview to list all the grouping records (single level nodes could be more than thousand) and each node with a tool tip to display the details. Sample code like this.

 

<telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True" DataSourceID="ObjectDataSource2"

 

 

DataFieldID="requirementno" DataValueField="reqno" DataFieldParentID="parentrequirementno">

 

 

<CollapseAnimation Duration="100" Type="OutQuint" />

 

 

<ExpandAnimation Duration="100" />

 

 

<NodeTemplate>

 

 

<asp:Label ID="Label6" runat="server" Text='<%# Eval("displayreqno") & "-" & Eval("ShortRequirement") & "(" & Eval("qtype_display") & ")" %>'></asp:Label>

 

 

<asp:Image ID="img1" runat="server" AlternateText="Test plan associated or not" ImageAlign="Baseline"

 

 

ImageUrl="menuimages/delete2.png" />

 

 

<telerik:RadToolTip ID="RadToolTip1" runat="server" Width="400px" Height="150px"

 

Skin="Outlook" TargetControlID="img1" Position="BottomCenter" Animation="Slide"

ManualClose="True" Text='<%# Eval("Requirement")%>'>

</telerik:RadToolTip>

 

 

 

</NodeTemplate>

 

 

</telerik:RadTreeView>

 

 

<asp:ObjectDataSource ID="ObjectDataSource2" runat="server" SelectMethod="GetAllRequirements"

 

 

TypeName="DocumentManagement">

 

 

<SelectParameters>

 

 

<asp:SessionParameter Name="projectid" SessionField="ProjectInfo" Type="Object" />

 

 

</SelectParameters>

 

 

</asp:ObjectDataSource>

when records is over thousand the performance becomes very bad. Any idea ...?

Thanks very much!
