For example, if we save the cell named mycell,{id: rowid, mycell: cellvalue} is added to the url. \\ If cellsubmit is 'clientArray', no ajax request is made and the content of the changed cell can be obtained via the method getChangedCells or thru a event. |remote| |

| + | ==== Examples ==== | ||
| + | |||
| + | When using the 'remote' setting you could add these lines to your grid configuration: | ||
| + | |||
| + | <code javascript> | ||
| + | { | ||
| + | 'cellEdit' : true, | ||
| + | 'cellsubmit' : 'remote', | ||
| + | 'cellurl' : '/url/to/handling/the/changed/cell/value' | ||
| + | } | ||
| + | </code> | ||
| + | |||
| + | When your are using 'clientArray' as cellsubmit setting, only these settings are important: | ||
| + | |||
| + | <code javascript> | ||
| + | { | ||
| + | 'cellEdit' : true, | ||
| + | 'cellsubmit' : 'remote' | ||

| + | ==== Event calling stack ==== | ||
| + | |||
| + | Depending on your cellSubmit setting set to 'remote' or 'clientArray' the following events will be fired in the following order: | ||
| + | === cellSubmit setting 'remote' === | ||
| - | Below is the order of which the events are called when the cellsubmit option is 'remote' | + | - **formatCell** (//rowid, cellname, value, iRow, iCol//) : You can change the cell value here which will be used in the edit mode |
| + | - **beforeEditCell** (//rowid, cellname, value, iRow, iCol//) : Just before the cell jumps into edit mode this event is fired | ||
| + | - **afterEditCell** (//rowid, cellname, value, iRow, iCol//) : Just after the input element is created this event will be fired | ||
| + | - **beforeSaveCell** (//rowid, cellname, value, iRow, iCol//) : Fires before the cell is saved, you can save the value here which is send to the server. | ||
| + | - **beforeSubmitCell** (//rowid, cellname, value, iRow, iCol//) : Fires before value will be send to the server, you can add extra parameters here to the request by returning an array | ||
| + | - **afterSubmitCell** (//serverresponse, rowid, cellname, value, iRow, iCol//) : Fires only if saving cell is succesful, you can return a error message here that causes a dialog with the message | ||
| + | - **afterSaveCell** (//rowid, cellname, value, iRow, iCol//) : Fires when the value of the cell is saved | ||
| + | - **errorCell** (//serverresponse, status//) : Fires when a server error is occured (like: 403, 404, 500, etc) | ||
