Hi again
(A barrage of questions today!)

When creating a custom column grouping via ColumnGroupsViewDefinition, I noticed a few things that puzzled me:-

-I could no longer move columns around or use the columnchooser
-I'm unable to provide different right-click context menus for data and "sub" header cells.  (Subgroup headings they do not register as GridHeaderCellElement or GridHeaderRowElement but appear to be GridDataCellElement)?
-I can only "pin" the main headings

I suspect a lot of that is by design, but if there are any avenues that I could use to enable a user to select what columns or even columngroups that they wish to see without losing the nice multi-row headings, it would be great!

Regards,
Mike

Hi Mike,

Thank you for contacting us.

Regarding your questions:

1. Yes, this functionality is limited when using column groups and html views. We plan to implement it in one of our upcoming releases.

2. Actually, they are GridColumnGroupCellElement elements. You can add you own context menu by handling MouseDown event. We will take your feedback into consideration when developing our future releases.

3. Yes this is done intentionally. It will become a mess when you pin some cell and the group is not pinned. Please describe what is the exact behavior that you expect in this case. We will appreciate your feedback.

Should you have any questions, we will be glad to answer.

Kind regards,
Jack

Thanks Jack,

Regarding question 3, I wasn't looking to pin non heading cells, just to be able to do more with the columns / groups.

I'd personally like to be able to rearrange columns within each group (as well as show/hide a column chooser of columns that are within the group but may be invisible), and hide/show the groups themselves. I'm pretty sure with the lead on "GridColumnGroupCellElement", I'll be able to implement something that does the basics here.

Regards,
Mike

Mike,

I'm looking for the same functionality. Would you be able to share your solution for having a column chooser while defining a custom ColumnGroupsViewDefintion?

Any help would be greatly appreciated.

Thank you,
Tim

Hello Tim Weckx,

Currently the column chooser is not available when using the column groups view. We know about this limitation and we plan to implement the feature in one of our upcoming releases. Should you have any other questions, don't hesitate to ask.

Kind regards,

Hi Tim,

My solution didn't extend to the column chooser in the end- the feature I needed to implement most was custom right click menu for data within the grid, which I achieved with some Telerik help.  Besides that being able to build and group columns manually was sufficient.

Regards,
Mike

Hi Mike Renwick,

You can subscribe to ContextMenuOpening event where you can add new item if ContextMenuProvider is GridHeaderCellElement. You can use the following code snippet that demonstrates this approach:
void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    if (e.ContextMenuProvider is GridHeaderCellElement)
    {
        RadMenuItem menuItem = new RadMenuItem("My Item");
        menuItem.Click += new EventHandler(menuItem_Click);
        e.ContextMenu.Items.Add(menuItem);
    }
}
 
private void menuItem_Click(object sender, EventArgs e)
{
    // Your operation here
}

If you need further assistance, do not hesitate to write us back.

Are there near future plans to implement the ability to move columns with in ColumnGroups?  And maybe even move entire ColumnGroups?
