exception of type 'system.outofmemoryexception' was thrown.

Hi,

It seems like "exception of type 'system.outofmemoryexception' was thrown" is a common error that people are having using the RadGrid; however, I can not find any real solution that works on the forum. My dataset contains 3.5 million records for 80 rows of data.

Regards,

Kelly

Hiding But Not Disabling Scroll

Hello,

I have two RadGrids, g1 and g2, on a page and both have vertical scrollbars. The g1 scrollbar controls the vertical scroll of g2. I would like to hide the vertical scrollbar in g2 but not disable the scrolling.

How is this accomplished?

Thanks,
John S.

GridCommandEventArgs.Item is null in InsertCommand

Hi, I am trying to follow your example in the Telerik help pages (http://www.telerik.com/help/aspnet-ajax/grid-inserting-values-inplace-and-editforms.html) to implement inserting a new row into a RadGrid. I am using a button to fire InitInsert which successfully creates an empty row that the user can input information, but when I fire the InsertCommand by clicking another button, in the InsertCommand event handler, GridCommandEventArgs.Item evaluates to null. Any suggestions?

scroll to last row of RadGrid after binding?

I searched the site for this question, sorry if I missed it.

I have a RadGrid. I add to the datasource. I rebind the datasource to the grid. I want the grid to be 'scrolled' to the bottom after the postback so the user can see the row they added. How is that done? Currently after the postback the grid is 'scrolled' to the top.

Thanks.

Grouping Problem

Hi I'm working with telerik radcontrols for asp.net ajax q2 2010, I'm using the grouping property of the grid by following the next sample demo. http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/outlookstyle/defaultcs.aspx

I'm grouping the grid's item by date but instead of getting the result like the demo I have groups of 1 items no matter if the date is the same. And I want to have all items of the same date in one group like the demo.

This is the code of my grid
