My apologies in advance.

I know this question has been asked millions of times. I've seen them all over the place in the forums. 

However, I'm not really sure that, all those times, the right question was actually asked. So, please, let me try for the 1000001 time:

I have this table with customer info of all kinds, which when fully expanded, takes tens of thousands of records. I would like to show this table to the users of my application using a RadGrid. Of course, I don't want to shove the full contents of this table at once to my users' throats; I would like the data to show gradually, as the users scroll in the table, in chunks of 100 by 100 (preferably).

Using many, many techniques, the RadGrid can do this just fine.

Now, I would also like to enable this cool functionality of the RadGrid that, when a user drags a column cell to the top of the grid, the grid automatically groups the data and displays it hierarchically, much like a tree view, with one, two, or many columns if needed.

So, you see, basically I would like (as the title said) Outlook-style grouping, *and at the same time*, on-demand loading of data into the grid, to make my users' life easier. 

Is this feasible, at all, with the current version of the RadGrid? What is the right combination of techniques that will let me do this thing I just described? Name them however you want, I don't care. Just, please, tell me what can I do to implement such a scenario.

Any comments will be highly appreciated!

Hi,

I resize my grid when the window load. It works well for every browser except Internet Explorer. The grid is always "null".

I tried what they say in this thread, but this is not working, so I guess I got something different.

Here is my code (jQuery):


What am I missing?

I don't want to use pageLoad because it fire before Pictures are load, that's why I'm using $(window).load().

Thanks

Hi,

    How can we set the columns property of textarea inside RadMultiPageView using javascript.Please reply ASAP.

Implement a custom appointment provider. Is there a mechanism for the provider to get the resources once and then keep them in the scheduler for duration of the page? I would expect the provider to supply the resources and the scheduler to keep them until they are explicitly changed (ie. for another view). But in my case, the provider has to get the resources from the database every time it is accessed (ie. getting appoitments, adding appointment)

I have overridden GetResources(ISchedulerInfo schedulerInfo) to return the resources available to the scheduler; however, it doesn't seem right to me that it queries the backend for the resource definitions on every postback.

If I set the resources programmatically the scheduler seems to maintain the resources on postbacks. For example...


What am I missing with the implementation of a custom provider? How do you get the provider to supply the scheduler with its Resource collection just once.

Thanks.

Hi,

I have a radgrid in which I'm binding the data. For instance I have the column "SER" in the grid. The value of "SER" in the grid is
"NG  101101". The length is fixed i.e 10.

When i export the above data using export to excel, the radgrid exports the above data to "NG 101101".  It removes one space. I don't want the excel to remove the space. I need to maintain the data as such.

Could you please help me achieve what I want.

Thanks,
Raji
