i would like to expand or collapse the group by clicking on the group name.
my code crashes at e.Item.Group because Group is null.
why is group null when i click on the group name?

        private void Operation_lv_ItemMouseClick(object sender, ListViewItemEventArgs e) {
            if (e.Item.Group != null) {
                e.Item.Group.Expanded = !e.Item.Group.Expanded;
            }
        }

many thanks

and the property name is blank. However, I can continue to work with the grid and click on different rows, it is just when I open the form and immediately click on the grid, is when I get this message. Thanks for any help.

You have an excellent example of how to do CellFormatting on a Details ListView for a Bound list.  My issue is trying to mimmic the same effect with an unbound list.

how do i select an item programmatically in my listview so that the group is expanded, the item is selected and current, like radgridview isVisible = true, isCurrent = true ?

thanks

Hi,

Is it possible that each time we select a new item in the autocompletebox, the selected item disappears from the list of auto complete items.

This is to avoid to enter twice the same items.

If this is possible, how to do it?

I put an attachment to show what is my current behaviour. What i would like is that once if have selected tag, it does not appears anymore in the list of choice

FYI, I am using auto completion with unbound mode.

Thanks a lot

     Hi 

Hi, 

Sometime the last chat message does not appear when the scrollbar is visible, to reproduced:

1- Type Test <ENTER> multiple time until you see the scrollbar

2- Scroll up to the middle so you can't see the last message

3- Type any word and scroll down

Now you can't see the last typed message, instead you may see small dot, You may need to repeat step 3 more than one time.

I'm not sure if it is related to Fluent Theme, because I wasn't able to reproduce it with Crystal Theme.

Thanks

I have a column with which get's edited using the ListViewDateTimeEditor.

The question is, how do I format the value that gets submitted to the ListView.

To be clear, I have already formatted the ListViewDateTimeEditor to use the following: 

Even with this formatting, it still submits the full DateTime to the ListView when finished editing.  How do I make it output only the formatted Date value, without the Time?

Hello,

I have 3 hierarchical levels in my grid. Here is the structure:

Master template

|___tab1: Details (html view)

|___tab2: Orders (standard grid)

       |___tab2-1: Clients (standard grid)

|___tab3: Networks (standard grid)

I'am inspired by some posts in the forum to save and restore the expanded rows and selected rows. It works great.

I save the grid state before data refresh, and reset after data refresh. Here is the code.

But I've found that the current selected tabbed view in the expanded row is reset to default after refresh.

How can I save the current selected tabbled view index for the expanded rows ?

Thank you by advanced.
