error loading radchart

Hi I am getting the exception: "Error Loading Radchart" on my application whenever the "authentication" tag is set in my web.config. If I run the application without using the "authentication" tag then it works.

Any idea of how I can resolved this issue?

[Solved] Manually trigger SelectedIndexChanged event ? Might need concept change

Hi,

Here are the scenario :
1) There are 2 combo boxes : Topic and SubTopic . One topic has one-to-many subtopics.
2) The selection of the topic will determine the list of the displayed subtopics
3) RadAjax has been configured on the topic combo box so that it will trigger the topic_selectedIndexChanged event by using AJAX. the topic combo box has been configured with AutoPostBack = true
4) The AjaxSetting has been configured to this :
              <telerik:AjaxSetting AjaxControlID="ddlTopic" EventName="ddlTopic_SelectedIndexChanged">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="ddlSubTopic" LoadingPanelID="LoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>

Here are the issues :
1) At the "create" form scenario, when i obtained the topic and subtopic value from the UI (user interaction), this is working well.
2) At the "update" form scenario, when i need to configure the selected topic value as well as selected subtopic value, i need to manually trigger the topic_selectedIndexChanged event to prepopulate the subtopic combo box, from the server side.

One of the alternative that i have think of , which is not quite elegant is to populate the data source of the subtopic and then set the subtopic selected value.

Please let me know if my approach is not correct or any insight to my issue.

Regards,

hadi teo

Grouping Totals displaying incorrectly

I just noticed that in a grid I have been working on is displaying group aggregate totals incorrectly. This occurs any time I group more than one column together.

Here is a link displaying the problem: Grouping Problem.

Here is the relevant aspx code for the grouping:

    
                            <telerik:RadGrid ID="CurrentCostCentersGrid" runat="server" Skin="Vista" AllowMultiRowSelection="True"

Dear Support and comunnity,

I'm really confused. I try to bind a grid in a very simple and codeless way.
The db is an access mdb with one table for testing,

It doesn't matter what I'm doing, Edit, delete, insert or refresh, because I add an item manuely, nothing
happends right no. No action ist execute.

Can someone tell me why. Hope its not to simple ;-)

Here ist the link to the demo VSO 2008 project:

Decoration delay ...

Am I the only one that experiences a delay in the rendering - e.g. you can see the original controls during page load and the skin is applied when the page is finished loading. This of course dramatically increases when the page being loaded is large and doesn't look professional. ... and yes, I am using <head runat="server" ...> In fact this is also slightly reproducible in the online demos.

Any workarounds on this?

RadTreeView NodeExpand

Hello,

I have used RadTreeView control in a ASP.net page and below code will add nodes to the tree considering whether there should be child nodes.

               if (childNodes.Count() > 0)
                    {
                        node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;
                    }

                    treeViewControl.Nodes[0].Nodes.Add(node);

The nodeExpand method will load the child nodes for a particular node when it is clicked.

When a node is expanded a serverSide postbak happens and so that the member variables in the class is re-initialized. Is there a way that i can avoid this?
I need to keep a variable value through out the node expandings till a page closes.

Thanks,
Sudesh

how to style the left bar with arrows in hierarchy display

my RadGrid has 3 leves: mastertableview --> detailtables --> detailtables.

It becomes hard to distinguish different levels as the records grow to a large number. Is it possible to change the colour of the left vertical bar which has the expand arrows?

thanks in advance
