Hi,

In a thread I working through our very slow Database (No its not SQL) and fill the Data in a DataTable. When a new row gets added to that DataTable I want to add the new row to the RadGrid as well. I thought iIwould increase the Rows.Count poperty and read the Row Info out of the DataTable in the Controls CellValuenNeeded event. The problem is that I get always an unhandlet exception sonner or later. When i remove the Event, the Datatable gets loaded correctly in the background.

Am I doing something wrong or do I use the wrong approach? Even locking has not helped me out.

Hope you can help me here.

Thanks

Listbox feature

I am new to Telerik and have a basic question. Does the Winform Listbox have the same feature set as the ASP Listbox? I am looking for item reordering and the ability to transfer from one listbox to another. Thanks...

[Solved] RadDropDownButton

Hello Telerik Team,
I need to add functionality to dropdown buttons in our project (hook up Initialized event). However, when i tried to do so I have encountered problem with Layout of subclassed control. I have solved the problem by overriding following property
   public override string ThemeClassName
        {
            get
            {
                return "Telerik.WinControls.UI.RadDropDownButton";
            }
            set
            {
                base.ThemeClassName = "Telerik.WinControls.UI.RadDropDownButton";
            }
        }

is this valid solution? I have no idea why subclassed control got "wrong" layout. Is there any reference in documentation that would help me understand why this problem occured?

ContextMenu Property Dropdown Blank

I followed the instructions here: http://www.telerik.com/help/winforms/tree_designcontextmenus.html for adding a default context menu to a treeview. However, when I go to the treeview properties to set the radcontextmenu to the new menu I added, the drop down is blank (well it says none).

what exactly might I be doing wrong?

Localisation

I have some questions für the localisation of the radcontorls ( grid, scheduler, ... ).

I haven't found a place where delevopers can share localisations for their languages ( for example german, french, spain, ... )

1. Exist a place where developpers can share their localisations ?

2. If not, would it be possible to create such a place ( for example an additonal subforum ) ?

Regards,

Ramius

Combobox value changes

Hi,

here is my problem :
I have a radtabstrip with several tab items : the first item is a panel with a list of records, when you double click on a record, all the infos about the record are displayed in a new tab so a very easy application ...
Some informations about records are displayed in combobox plugged on binding source (a new binding source is created for each new tab so that the combobox are not linked).

The problem is when I open a second tab about a record, when I click on the tab of the first record, combo are initialized to the first value of the list and don't remember the initial value of the record :( The last tab item always have the right info in the combobox but all others tab items are reinitialized and I don't understand why :(

Thank you for your help, if you have any question I'm here to explain better my problem ...

Setting Visibility on GridRowElement not having disired result

In a cell formatting event, I need to hide a row based on a cell value. Here's my code:

cellElem.RowElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

However, the row is not collapsed. It's hidden, but still takes up real estate on the grid. I also tried setting Visibility and IsVisible on the RowInfo object and it did not product the correct behavior either.

I'll describe what I'm doing before asking my question. I have a form that is using the grid control and would like to open a new form window with the data from the row that was selected. What's the best way to pass the currently selected row to a new form?

Thanks.

TreeGrid

Hi,
is it possible to use GridView as a kind of "treegrid"? I don't mean hierarchical grid with new separate grid for each level or gridview with automatically added group rows. I think something like editable multicolumn treeview. I'm deciding between componenone and telerik and in componentone gridview is this possible. But I can't find how to solve it in the telerik gridview.

Thanx
