Re: [Wicket-user] Editable grid
Actually we have gone completely Ajax for the grid, so i have no idea what problems you are going to run into when using forms, especially in combination with a moving editor. our grid was based on a listview using wicket 1.2.6 but 1.3 might have better alternatives.

Re: [Wicket-user] Editable grid
An editable grid is certainly possible in wicket. I've build one of those monsters in our application. Unfortunately for you it has grown so much to be able to do everything you ever wanted and everything you never even knew you wanted that it is completely useless as an example. I can however give you some tips. - Do not use textfields or dropdowns in every cell, especially with larger grids this is going to hurt you performance wise (ie more than firefox but still) -instead use one moving textfield (or a dropdown for each different type you need) -use spans to create editable labels (showing the textfield or other editor on click) -if you are going to use ajax, send multiple changes each time using the time delay -if you use something of a form submit you will need to collect the changes in a custom way since you don't have textfields. -get ready for some serious javascripting (i have some javascript to navigate a table in javascript you should be able to reuse). -make good use of the component structure of wicket building on cells, rows and tables (off course you need to build these yourself). -really think your underlying datamodel through, we are using 1 custom model to dispatch models for each cell. but i'm not sure this is ideal. -inline attribute changes on your cells by overriding the oncomponenttag to minimize your footprint. -Keep it simple Maurice On 7/10/07, Sanjay Gupta [EMAIL PROTECTED] wrote: I have recently started playing with wicket to see if we can use it to rewrite a legacy enterprise.
