Column Chooser

[Jebamalai]

Dear All,

Like in RAD Windows Grid Control, is there any option available in the Web Grid for choosing the columns?

Hi Jebamalai,

This functionality will be available in our upcoming new version (Q3 - early November).

Hello,

The Q3 RTM is now available, and I'm wondering if you could point out the section of the documentation that explains the new column choosing capability.

So far I haven't been able to location any information on how to use this new feature.

[Mark]

Please disregard my last post, I was able to find this:

http://www.telerik.com/help/aspnet-ajax/grid-header-context-menu.html

Which correlates to the Q3 beta demo here:

http://demos.telerik.com/aspnet-ajax-beta/Grid/Examples/GeneralFeatures/HeaderContextMenu/DefaultCS.aspx

Now I'm wondering... how would one go about persisting the column header selections made by the user across separate page views? I can see that the column choices are carried through ViewState, but what if the user leaves and returns at a later point?

Thanks again!

A tasty tip Yavor, thanks for the pointer.

I have got the header context menu plugged in and working (awesome!). One thing I would like to do is have the checkbox menu *not* display the GridEditCommandColumn and a GridButtonColumn (for deleting the record) in the list. I'm sure this is done on the client side, but didn't see any real hooks to handle when the menu was built. I saw plenty to handle when the column was hidden.

Any suggestions?
I'll dig some more and post if I find something worthwhile.

That absolutely did the trick. I'm guessing I can also use this approach to hide other columns as needed? (in the case the app caches column visibility as well), the prior link in this thread looks to be the perfect place to start.

[Yavor]

Hi Martin,

Indeed, you can use this approach to hide any of the columns in the columns collection of the menu.

Kind regards,

What a nice feature this is!

However, during testing on some platforms, I've noticed a rather egregious deficiency with the backing javascript. My target broswer is FireFox 3.x

I have tested the functionality running this app through the browser on OS 10.5.5 and WinXP SP3

On the windows side, the right-button click on the grid header brings up the menu at any location on the header (above the column text; hand cursor, on the column header itself;pointer cursor, and next to the column header edge; resize cursor)

This however is not the case on the Mac. The menu is only activated when the cursor is in the resize region. I have firebug installed and no JS errors are being thrown. To make matters better/worse, I have verified this same behavior on a RadGrid demo (http://demos.telerik.com/aspnet/prometheus/Grid/Examples/GeneralFeatures/HeaderContextMenu/DefaultCS.aspx) on both platforms.

I am stymied on how this would be fixed. Is it a simple CSS fix, or is there some OS/Browser disconnect that is not catching the right-button click correctly?  If this needs to be moved into a new thread or into a ticket, so be it.

I would like to raise the postback event while clicking of column choosing checkbox, because i need to save the radgrid even column chooser also. postback occur while click of other items in header context menu, but it is not postback when i click column choosing checkbox.
can u please tell me the way to raise the post back event while clicking of column chooser checkbox..?

and one more thing i need to know . how to restrict the certain columns in cloumn chooser..?

[Mike]

Is this fixed?

[Yavor]

Hi priyan,

You can subscribe to the onColumnHiding/onColumnShowing client side event handlers, to intercept the case when the end user shows/hides a column. From there, you can trigger an AjaxRequest to the server.
I hope this suggestion helps.

Hi Martin

Did you fix that issue? (HeaderContextMenu on MAC OS)?

and if so, how?

I have similar issue, the HeaderContextMenu works fine with Windows machine and also with Safari in MAC but Firefox no.
as Firefox is our default browser.

any idea?

Thanks

Hi Grand Lorie,

It works like a charm with FF, Google Chrome, and IE 9. Try with FF 9.0.1
