Hi,

Im using the AsPXGridView from DevExpress and Im wondering if it is possible to limit the number of entries in the grid. For example, the grid may start with no entries and the user clicks 'New' and creates an entry.

When the user has added the maximum number of entries the 'New' button is removed and only 'Edit' and Delete are visible.  If they Delete an entry then New is visible again etc.

Is this behaviour possible?

Have a counter increment each time they hit a New button and decrement when they hit Delete.
On page load have if counter > some ammount NewButton.Visible = false; else newButton.Visible = true

What Im really asking if this is intrinsic to the grid itself.  The Grid is smart enough to know when there arent any entries at all as you only get the 'New' button.  When there is one or more you get New/Edit/Delete.  Im wondering if there is a property like 'MaxEntries' that can be set on the grid so that the New/Edit/Delete behave accordingly when that maximum is reached

not according to intellisense or the gridview properties list, as Epitel said your best bet is to hide the button, possibly on the insert event if the row limit's been reached.

Im actually talking about the AsPXGridView from DevExpress and not Microsofts GridView control.  Turns out there is a CommandButtonInitialise event on this grid in which I can check the rows in the grid and hide the buttons accordingly

The desired result has also been sugested by me and mr_nadger, it is objectionable that the asker be allowed to close the question without giving us the points and keeping the question in the knowledge base, especially since he decided to change the essence of the question after getting a possible solution.

Yes, I am relatively new here and yes I am aware that I can choose as many comments in the solution.  As I didnt implement the suggestions as 'the solution' how can I award the suggestions points?  I would need to implement those to make sure they worked in order to classify them as 'A Solution'.

The properties comment was talking about a totally different grid than the one I had asked about.

I would have thought that the solution you actually use is the one most relevant as that has had some form of testing done against it.

Anyway, Im not too fussed with what you want to do in regard to awarding points etc, happy to award the points as you described

All,
 
Following an 'Objection' by Epitel0920 (at http://www.experts-exchange.com/Q_26622855.html) to the intended closure of this question, it has been reviewed by at least one Moderator and is being closed as recommended by  ModEErf.
 
At this point I am going to re-start the auto-close procedure.
 
Thank you,
