Hi Telerik Team,
We are trying to make monthly chart in which series are being created Dynamically. On X-axis, we need to group chart with Months Name. I also tried your sample application and also following same steps in my application. But it shows me some inconsistant values (Mean it is not showing values according to proper months). I am selecting records using Linq Entity framework and keep them in Data Table. When i receive records in datatable, data is to be shown properly but when i pass this datatable to my Rad Chart control then it shows some inconsistant values. Can you please guide us that how we can solve this issue.

Regards,
Ascertia Team

question about nestedviewtemplate sample

hello I've started look into nestedviewtemplates and have a couple of question

1. http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx in this sample, the sales grid consists of a detailview table. the sqldatasource has a sessionparameter. Now i Assume that the parenttablerelationship-settings do put the correct value inside there and that it should be asp:Parameter instead - because i cannot see where the session parameter is set.

2. My other question is how to achieve what is done in the nestedview sample programmatically? Using the sqldatasources and binding to the hidden Label to use as ID and then use controlparameter seems pretty okay. But what if there's a scenario where i cannot use the parameterized datasources? I looked into the documentation and found the OnDetailTableDataBind event which i have successfully used to fetch data and bind it to detailtables, but how can it be done in nestedviewtemplates?

i haven't tested the sample extensively but i suppose the fact that nestedviewtemplate consists of tabstrips, detailviews etc adds to the complexity of databinding programmatically?

[Solved] Refresh a WCF-bound grid

Hi,

I have a WCF-bound grid that works fine. I have the user select one or more items, click a button, which opens a Window for editing. All this is fine.

I have an event handler on closing of the window and in this I want to be able to update the grid with the changes. This, however, runs the code but does not retrieve the changes by calling the WCF service.

My JavaScript:

                    var grid = $find('<%=radGridDataGroups.ClientID %>');         
            var selItems = grid.get_masterTableView().get_selectedItems();         
            if (selItems.length == 0) {         
                radalert('Please select an item to edit and then try again.', 300, 100, 'Edit Data Group');         
            } else {         
                for (var i = 0; i < selItems.length; i++) {         
                    var w=migOpenDialog('~/secure/dialogs/system/EditDataGroup.aspx?dataGroupID=' + selItems[i].getDataKeyValue("DataGroupID"), 600, 600);         
                    if (w) {         
                        w.setActive(true);         
                        w.set_modal(true);         
                        w.add_close(function() {         
                            alert('hello');          
                            var masterTable = $find("<%=radGridDataGroups.ClientID %>").get_masterTableView();         
                            masterTable.rebind();         
                        });         
                        w.show();         
                    }         
                }         
            }         

So the 'hello' message is displayed (I have also put breakpoints in there). I have stepped through the $find call, which gets the grid and the rebind method appears to run, but nothing happens.

So how can I refresh a WCF grid based on changes?

Note: migOpenDialog is just a wrapper for your openWindow function.

Many thanks

Adding large amount of items on client side

Hello,

How can i quickly add 5000 items to the list control on client side?

I can use the _addNewItems("", options) in RadComboBox, do you have any similar method in RadListBox control which allows to avoid creating RadListItem javascript objects one by one?

Thanks

Hi

I have a grid which allows me to edit the row. Updating works fine. However when I use the itemupdated event handler the row does not update. The itemupdated eventworks fires fine though.

Is there something else I must do when I use the itemupdated event or is this a bug?

Thank you

Grid sorting, filtering and paging in an n-tier soa application

Hello,

we are developing a client/server 3-tier application and need to filter and sort huge amount of data. Let me first explain the current situation.

WebSite <-> ApplicationServer <-> Database
WinApp <-> WebService <-> ApplicationServer <-> Database

The Website calls the methods in the applicationserver directly e.g. "Users.GetAllUsers()".
The WinApp calls the same method via webservice.

Our current grids show the data in the sort order returned by the method above. Now we need to implement sorting/filtering and paging on the grids and we'd like to use the standard funktionality of the grids. As we have a 3-Tier application i do not want to directly connect the grid to the database, merely i want to connect the grid to the ApplicationServer.

Does anybody know how we can achieve this in an elegant way? It should work over webservices, too.
I was thinking of getting a serialized expression tree from the radgrid that i can send to the webservice which itself manipulates it and sends it to the database. The data is then returned to the grid.

Any ideas?

Validator position fault

Hi,

I have just found some kind of fault in the advancedFormTemplate system. Validators position themselves wrong, even in the official example:
http://demos.telerik.com/aspnet-ajax/scheduler/examples/advancedformtemplate/defaultcs.aspx

If you open one of the appointments, delete the subject, submits the form and then clicks on the subjectfield the errormessage appears a weird place.

What can I do to correct this?
What can I do to get full control of the position of the errormessage?

Regards
Rune
