Can't cancel editCellEnding

Chris posted over 12 years ago

I can't stop event propagation from the editCellEnding event. In the event a user enters something other than a number, I show them an alert and want the focus to remain on the current cell, and it to stay in edit mode. If I try this and enter an invalid value and tab away, then the alert is shown but the focus is moved to the next cell and it enters edit mode. I've tried stopPropagation, stopImmediatePropagation, preventDefault and just returning false but nothing seems to stop it.

editCellEnding: function (evt, ui) {
                                
                                if(ui.value!='' && isNaN(ui.value)){
                                    alert('Not a valid scoring number');
                                    evt.stopPropagation();
                                    evt.stopImmediatePropagation();
                                    evt.preventDefault();
                                    return false;
                                }

Hi Borislav,

I appreciate that. Unfortunately I didn't have the time to wait, and it seemed like everyday I was bumping my head against at least one shortcoming or issue of the igGrid for a couple of weeks, multiple ones of which got entered as bugs for the next service release. I was able to take jsViews, build my table template dynamically for it, apply the Editable library, jQuery Sorting & Pagination, add new rows and complete the task in under 3 days. I was even able to add my own custom keyboard navigation in that timeframe (tab at end of row goes down to next row first editable cell, down arrow/enter move down and start next column at end, etc... )

Maybe I'll try igGrid again sometime, but I can't waste any more time on it currently and not again until it's a bit more robust (and more fully documented). Thanks again though.

Hi Chris,

After discussing development issue #117141 with our developers it turned out that I was wrong - the column index is correct in the editCell* events - so I admit that I got a bit hasty in submitting that.

About the sample I promised you - it's doable with in row editing mode, because the rowEditEnding event has an input param called ui.keepEditing - it allows the editor of the cell to remain instead of jumping to the next cell. Our developers will add this param to the editCellEnding event for the next Service Release so hopefully then (about a month from now) we'll have have a better out-of-the-box solution for you.

All the best,
Borislav

Hi Chris,

My issue isn't really validation but in trying to cancel the event and keep the focus in that cell.

Due to one reason or another, validation seems to be (based on my research and rummaging through the source code) the only good reason to keep the Edit Mode on the current cell instead of jumping onto the next one.
What the editCellEnding event does is, quoting its description from the official API reference: Event which is raised before end cell editing. Return false in order to cancel update of data source.
Thus is doesn't prevent the fact that Edit Mode will be switched to the next row or cell - simply that the change you've made won't applied to the data.

I'm currently working to create a sample for you that should do the trick, but I'm also encountering some difficulties so I'll have to ask you to give me some more time to prepare something good enough. I should have some time to continue working on it tomorrow, but I don't wan't to give you hopes just yet.

I'm confused regarding the hidden column you mentioned in your PPS statement. While there is a hidden cell in the grid, the cell that I was editting is not hidden.

The thing is that the editCellEnding event isn't aware of the fact that there's a hidden column so it's not calculating the column index properly - this is why I logged the development issue.

Thanks for your patience and understanding!
