Hierarchical Data Binding - SQL-2008

Hi,

I just finished watching the demo of new HierarchyID Data-Type in SQL-Server-2008, and the first thing that occurred to me (after I got up off the floor and back on my seat) was the possibility of using this for storing menus in the database, to get higher performance loading.

Has Telerik looked at this option for possible future variants of loading a menu from a database query ??

[Solved] ComboBox not updated on CallBack

Hi:

I have a RadCombox (ajax) and a RadWindow on a page. The RadWindow allows me to change some database records. When the RadWindow closes, I use AJaxManager to trigger a callback on the combo box.

$find(

"<%= RAJforForm.ClientID %>").ajaxRequest("Rebind_RcbL01");

I know the callback is triggered because I've debugged the code and RaisePostBackEventis is triggered as it should.

Now within RaisePostBackEvent event, I basically reload the combobox (RcbL01) right from the database. From debugging, I can see that the RadComboBox successfully bind to the datatable and RcbL01.Items(1).Text in fact was showing me the NEW field information under debug.

However, on the screen, the items inside the combo box do not update. They are still the OLD value (even though the server-side debug clearly shows the new values are bind to the combo box).

Any help to resolve this issue is appreciated!

Databinding with ControlParameter

Hi,

I have a RadGrid which is bound to a LinqDataSource. In the where parameter of the datasource I have a ControlParameter which references a RadComboBox. With this setup the content of the grid changes when the selection of the combo box changes. So far so good. The problem is, that on page load the combobox is bound to its datasource and displays its contents but the grid does not. The grid is updated when I firs change the selection of the combo box.

How can I fill the grid proprtly on page load?

Best regards,

Robert

[Solved] Update controls on mastertable item only

Hi Telerik team,

I could need some help on this. I have a RadGrid with detail tables. When an item in the mastertable is clicked, some controls are updated via the Ajaxmanager. But if an item in the detail table is clicked (and also when the detail table is expanding) the controls are updated too. But I don't want that, I only want the controls to be updated when a mastertable item is selected on a row click. How can I do this?
I read and tried several things in your documentation but so far I'm getting nowhere.

Thanks!

Geert

Filtering not working until i click no filter option

I am facing a strange problem in rad grids. Whenever I type something in filter textbox and filter, it works fine. However if I type something else after first filter, the same set of data is returned, unless I click no filter. However i know this is not the case in your demos site. I do not know if it is my mistake. However if you can advice how to track it down, then that would be very helpful.

Thanks in advance.

[Solved] Node Inspector customisation

Hello all,

I'd like some advice please - what is the most straightforward way to make adjustments to the Editor's Node Inspector? We wish to remove the options to adjust HTML attributes.

For example, when an image is selected we would like to remove the Width, Height, Alignment, Border Color and Border Width option, but retain Set Image Properties, Tooltip, and Classname. Is there an easy way to "turn off" the undesired options, or do we have to create a custom module with just the features we desire?

Many thanks,
Mathew.

Custom aggregates for multiple columns

I read in a thread from back in September that you could only access a single column that has its Aggregate property set to 'Custom'. I've been looking at the properties of the GridCustomAggregateEventArgs object that's passed into my CustomAggregate event handler and notice that there's an ItemIndex property, however it doesn't seem to change from the value -1. What's the suggested method for accessing the index (or, preferably, UniqueName) of the column for which the CustomAggregate event is firing?

Multi Add Functionality

Hello,

I want to utilize the Rad grid control on a web page which is heavily used for the data entry work. The way the user wants the grid to work is that they want to add all the records and then click a "Save All" button which will insert all the newly added data to the SQL server database. By doing so they want to prevent the post back / Ajax request to the server for every new record that is added and thereby save the data entry time.

Also, the number of new records to be added is not fixed, so when the user clicks on the tab key on the last cell of the new record a new row should get created and it should happen on the client side without hitting the server.

Is it possible to do this using Rad grid control? I have seen a demo where tool tip is used to achieve similar functionality but the users are not very confortable with that design approach. They want to do the data entry directly on the datagrid.

Please advice.

Regards,
Rajiv
