BindableList<> does not work as expected

If I have a list of objects that supports IEditableObject then I see some strange results when I remove a row.
The EndEdit function is called on the next element in the list or the previous if I remove the last element. The MS DataGrid does not call the EndEdit function when deleting a element.

[Solved] Sub menu in StartMenu disappearing when you have items in the right column

I'm seeing some strange behaviour when you put items in the right column of the start menu and you have childitems in the left column.

The popup for the childitems of the left always sits at the top and if you're left column item is further down to the bottom, there is a disconnect between the two of them. Trying to move the mouse from the left column item to it's child items popup, closes the popup before you get there. When there are no items in the right column, the popup stays, but when you have items in the right column, they receive the focus, and it closes the popup.

To reproduce:

Create a new RadRibbonForm
Add 4 items to the StartMenuItems
Add 1 subitem to the last item of the StartMenuItems
Add 4 items to the StartMenuRightColumnItems

Now, when you hover over the last StartMenu item, you can't get to the child item.

Combobox Modify Default Theme Q1 2010

I am using Q1 2010 and am a bit perplexed by the new visual style builder. I understand how it works I just can't get it too do what I want. This is what I want to do:

Load the default theme for the combobox.
Make null item text a different color.
When a null value is selected the border of the combobox is yellow.

This is probably easy and intuitive but I had finally conquered the old style builder and just don't have the time to tamper around with this one until I get it right. Any insight on this would be great. Thanks!

Binding GridView to heirarchical collection

I have a collection of say invoices that has a collection of invoice details or line items and a collection of payements. I want to bind the gridview to the collection without manually creating all of the columns and such. When I use the Invoice collection as the datasource I do not get the children of invoice, only the single column. I am setting autoGenerateHeirarchy. Do I need to define the relationships to accomplish this, even though they are well defined already?

Thanks

Rad Grid Row Edit, RowChanged event triggers if null values are present in row cells

I'm having an issue with RadGridView1_RowsChanged event. Normally this event will trigger if I modify the row content and moved to another row. If the row contains a cell with NULL values and I clicked on that cell and without editing I moved to another row, then also the RadGridView1_RowsChanged event triggered which is causing me issue. What I'm trying to do in my project is that I need to get the edited row details and update that to database on a button click. If I go through a null cell and moved to another row then also RadGridView1_RowsChanged event triggerd and my edited row index valu will change and I'm not able to save the details to database. Some part of my code is given below. Can anybody help me?

    
             private void radGridHome_RowsChanged(object sender, GridViewCollectionChangedEventArgs e)

Grid view - Wrap text??

Can you tell me how I get the grid view to wrap text and force the height of the cell to match the amount of text - IE exactly like in Excel where you select cell properties and select "wrap text"??

I really need a solution that is defined in the front end like the show/hide columns, expand widths etc, so the settings can be saved on the users end.

Can you tell me what i am looking for to achieve this?

Thanks

Decimal Column

Hi Experts,

I add decimal columns into my grid. My application is base on the example GridView/Columns/Column type example.

My problem is when I try to set the appropriate DecimalPlaces no change appear to the grid view. For example, it show 500.000 instead of 500.

I try to do a modification to the code of the Telerik Grid example and change the numeric column decimal places from 0 to 2 and I got the same result then in my application; decimal place didn't change and the numeric column still show 0 decimal places...

What I am doing incorrectly?

Thanks
Nadia
