Dear Telerik Team,

I am using RadGrid and a few splitter tricks for display and editing of large amount of data. In Edit mode, when the user keeps tabbing, the SAVE goes out of focus. Now the user has to click the right end of scrollbar to make the the Save appear all over again.

I am looking out to see if I can freeze the column that shows Update/Cancel (similar to the examples/demo shared out in http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-freeze-columns-in-radgrid.aspx)

How to make the column that shows Update/Cancel as Frozen?

I populate the ListItems of a ComboBox and Multi-Select ComboBox control inside the RadGrid's NestedViewTemplate using two other SqlDataSource objects. The SelectedValue of the single select ComboBox is easy to set. What is the most efficient means of setting the SelectedValue of the appropriate ListItems in the Multi-Select ComboBox?

with out post back how to invoke batcheditcommand from C#.net

used telerik:RadGrid batch editing; to fill this grid I used below syntax:

function GridBind(GridID, GridData) {
var TableView = GridID.get_masterTableView();
TableView.set_dataSource(GridData); TableView.dataBind();
}

To Invoke batcheditcommand I used below syntax. It’s written under non-postback button Javascript event:

function SaveAllChanges(sender,args) {
var batchManager = $find('<%=RadGrid1.ClientID%>').get_batchEditingManager();
var tableViews = [];
tableViews.push($find('<%=RadGrid1.ClientID%>').get_masterTableView());
batchManager.saveTableChanges(tableViews);
}

But unfortunately SaveAllChanges perform a postback and invoke RadGrid1_BatchEditCommand,my requirement is with out post back ,i want grid batch all change on server side.Any type of suggestion will be acceptable.
