Hey Guys

I am using RadTreeList and doing the hierarchical binding of data by keeping that in the update panel and doing server side binding using AjaxManager and keep the paging enabled.
Whenever I click on any page number or Group(-) Image on the top left of the tree list it throws java script error and treelist got crashed and is unable to find the id of the treeview in update panel and shows control undefined
Is there any other way to group the data on the basis of 'ParentI3D' and having sorting and paging functionality enabled

Here is the design of my treelist:

<asp:UpdatePanel ID="upPanel" runat="server" UpdateMode="Always">                     <ContentTemplate>                           <telerik:RadTreeList ID="gvCustomerMonitorFailures" runat="server" ParentDataKeyNames="ParentI3D"                         ClientIDMode="Static" DataKeyNames="I3D" AllowPaging="true" PageSize="5" AutoGenerateColumns="false"                         AllowSorting="true" ShowTreeLines="false" GridLines="None" AllowMultiItemSelection="true">                         <ClientSettings Selecting-AllowItemSelection="false">                             <ClientEvents OnItemSelected="gvCustomerMonitorFailures_OnItemSelected" OnItemClick="gvCustomerMonitorFailures_OnItemClick">                             </ClientEvents>                         </ClientSettings>                         <Columns>                             <telerik:TreeListBoundColumn DataField="DisplayName" UniqueName="DisplayName" HeaderText=""                                 HeaderStyle-Width="35px" />                             <telerik:TreeListTemplateColumn DataField="IsCheck" UniqueName="IsCheck" HeaderText="">                                 <ItemTemplate>                                     <img src='<%# ProcessMyDataItem(Eval("IsCheck")) %>' id="DisplayIsDeleted" alt=""                                         style="margin-left: 5px; margin-top: 5px; width: 16px; height: 16px;" />                                 </ItemTemplate>                                 <HeaderStyle Width="35px" />                                 <ItemStyle HorizontalAlign="Center" />                             </telerik:TreeListTemplateColumn>                             <telerik:TreeListTemplateColumn DataField="IsProblems" UniqueName="IsProblems" HeaderText="">                                 <ItemTemplate>                                     <img src='<%# ProcessMyDataItem(Eval("IsProblems")) %>' id="DisplayIsDeleted" alt=""                                         style="margin-left: 5px; margin-top: 5px; width: 16px; height: 16px;" />                                 </ItemTemplate>                                 <HeaderStyle Width="35px" />                                 <ItemStyle HorizontalAlign="Center" />                             </telerik:TreeListTemplateColumn>                             <telerik:TreeListTemplateColumn DataField="IsProcessorPerformance" UniqueName="IsProcessorPerformance"                                 HeaderText="">                                 <ItemTemplate>                                     <img src='<%# ProcessMyDataItem(Eval("IsProcessorPerformance")) %>' id="DisplayIsDeleted"                                         alt="" style="margin-left: 5px; margin-top: 5px; width: 16px; height: 16px;" />                                 </ItemTemplate>                                 <HeaderStyle Width="35px" />                                 <ItemStyle HorizontalAlign="Center" />                             </telerik:TreeListTemplateColumn>                             <telerik:TreeListBoundColumn DataField="Description" UniqueName="Description" HeaderText="<%$ Resources:CEntronResource, clmDescription %>">                                 <ItemStyle HorizontalAlign="Right" />                             </telerik:TreeListBoundColumn>                             <telerik:TreeListBoundColumn DataField="StartAsString" UniqueName="StartAsString"                                 HeaderText="<%$ Resources:CEntronResource, clmStart %>" />                             <telerik:TreeListBoundColumn DataField="FinishAsString" UniqueName="FinishAsString"                                 HeaderText="<%$ Resources:CEntronResource, clmFinish %>" />                             <telerik:TreeListBoundColumn DataField="Time" UniqueName="Time" HeaderText="<%$ Resources:CEntronResource, clmTime %>" />                             <telerik:TreeListBoundColumn DataField="FailureReason" UniqueName="FailureReason"                                 HeaderText="<%$ Resources:CEntronResource, clmFailureReason %>" />                         </Columns>                     </telerik:RadTreeList>                                                    </ContentTemplate>                 </asp:UpdatePanel>

Here is the Ajax request event which I used to call on my another control click:

      /// <summary>
        /// Handles the AjaxRequest event of the RadAjaxManager1 control.
        /// </summary>
        /// <param name="sender">The source of the event.</param>
        /// <param name="e">The <see cref="Telerik.Web.UI.AjaxRequestEventArgs"/> instance containing the event data.</param>
        protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
              
            //UserControl treelist = (UserControl)this.FindControl("serverComptDetailsView");
            UpdatePanel updPanel = (UpdatePanel)serverComptDetailsView.FindControl("upPanel");
            RadTreeList treelist = (RadTreeList)serverComptDetailsView.FindControl("gvCustomerMonitorFailures");
           
            CEntronRestServiceClient serviceClient = new CEntronRestServiceClient();
            RequestOfint request = new RequestOfint();
            request.Data = Convert.ToInt32(e.Argument.ToString());
            ResponseOfMonitoringDataFailureDTOHGZ00jlC response = new ResponseOfMonitoringDataFailureDTOHGZ00jlC();
            response = serviceClient.GetMonitoringDataFailureDetailByDeviceID(request);

            treelist.DataSource = response.Result;

        
        }

Hello,

I'm trying to implement the code at the bottom of this page as a test and I'm not sure what dll's I need to reference?

http://demos.telerik.com/aspnet-ajax/chart/examples/skinning/misc/defaultcs.aspx 

I have used both Telerik.WebControls.RadGrid and Telerik.Web.UI.RadGrid.

Telerik.WebControls.RadGrid has skin property as Windows (skin="Windows") and Telerik.Web.UI.RadGrid has skin property as Outlook (skin="Outlook").

Now I need the same styles for Telerik.Web.UI.RadGrid as like the Telerik.WebControls.RadGrid.

I have tried this by changing the skin as "Windows" name and EnableEmbeddedSkins="false" for Telerik.Web.UI.RadGrid. It applies some of its style as "Windows" but not similar as Telerik.WebControls.RadGrid.

Can anyone help me.

Hello team,

Sorry for my flurry of questions.

I'm binding a table having the columns A, B, C, D, E, F, G, H to the radscheduler and setting A, B, C, D as the DataKeyField, DataSubjectField, DataStartField, DataEndField.

My questions -

1. Now i want the tooltip to show the values from the columns E, F and G. How to do that?

2. What does Appointment.DataItem really return? Can i get the values of E, F and G from Appointment.DataItem? (I always get it as null)

Thank you once again.

Hi,

I would like to use the RadScheduler with an ASMX webservice for fetching appointment data. This works, but i would like to send some attributes along with the request so the SchedulerProvider can use this as a filter. Otherwise i have to get fetch a lot of data from my data layer.

I have tried to use the SchedulerProvider directly setting the property ProviderName on the RadScheduler and removed the webservice settings. When i add an attribute to the RadScheduler object, it is accessible in the SchedulerProvider. This way of passing filter values works, but not when is use the webservice.

Is it possible to send custom attributes along with the webservice call?
