I am new to d2005 so not sure how to go about achieving this. But I am trying to add/delete records in an ECO app with datagrid bound. what I would like to do is allow the user to automatically add a record if they have the last row of the grid selected and press the down arrow (or automatically add a new object if they start typing in the last row). However I cant seem to trap the onkeyup or onkeydown event of the grid even though I have implemented its events. Is there something that I am missing to do this? alternatively I would like to provide the user with a context menu on the grid. However I cant seem to get the menu to pop up when they right click on a column in the grid (but only when they right click on the grid's blank space). How do I assign a context menu to the columns?

I suggest you ask in the eco group. -- Marc Rohloff [TeamB] marc rohloff -at- myrealbox -dot- com

Marc Does it make a difference that it is ECO. As in if the app isnt ECO, would the onkeyup etc be the way to go to run code to add/delete records? The reason I ask is that all the code examples I have found via Google indicate other ways to achieve this (such as buttons etc) Regards Phil "Marc Rohloff [TeamB]" <"on request"> wrote in message news:rle95dsgx7qf.dlg@marcrohloff.40tude.net... > On Thu, 11 Aug 2005 07:48:17 +1000, Phil wrote: > >> I am new to d2005 so not sure how to go about achieving this.

The only way I can think of to make it act like Del[phi's DB Grid (which is what I assume you want here) is to add a dummy record at the bottom and create a new one each time the user edits it. -- Marc Rohloff [TeamB] marc rohloff -at- myrealbox -dot- com

Marc that sounds like what I am trying to do. My problem is that I cant seem to trap the onkeyup or onkeydown event. Is there any special trick to this?

The only way to get this sort of access to a DataGrid is to create a subclass of a DataGridColumnStyle (or usually base it off one of the existing subclasses) and link that up to your grid. -- Marc Rohloff [TeamB] marc rohloff -at- myrealbox -dot- com

I worked out how to do this. Basically for a textboxcolumn, I trap the onkeydown of the datagridcolumn.textbox and go from there. regards phil "Phil" <phillip.allenATiwl.com.au> wrote in message news:43015743@newsgroups.borland.com... >I am pretty new to this so can you please tell me how to do this? > > Regards > Phil > "Marc Rohloff [TeamB]" <"on request"> wrote in message > news:1jwpt0lwu77e4.dlg@marcrohloff.40tude.net... >> On Thu, 11 Aug 2005 14:03:30 +1000, Phil wrote: >> >>> that sounds like what I am trying to do.
