I want to have my AgGrid editable and want to run validation logic before a row is saved. So, basically when a user clicks the cell, enters into edit mode, edits a few cells, clicks away - the row is SAVED (unless validation fails).
I started with setting
editType="fullRow"
readOnlyEdit
on AgGrid. This allows me to get multiple onCellEditRequest events when I click away from the row (=save the row). But ideally I want to receive single event with all edited cells (or a full row data).
Is it possible? Can I request this feature on AgGrid?
You can use the onRowValueChanged callback. This will be called once you save any changes within the row.

I have a combo box in an Access form with 2 values Yes / No. The user opens the form and enters the reference number and pushes a button to run a macro. The macro executes a query to return data based on the reference number. The results of query are displayed in various text boxes.
After the combo box is built, the macro selects the appropriate value based on the query. The problem I'm having is that the "change" event is triggered because the combo box is loaded for the first time. I want to prevent this.
After reviewing the data, the user can choose to change the value in the combo box. At this time, I want the change event to fire because the additional macros are run that update multiple tables in the database.
Can I prevent the "change" event from firing when the form is loaded with data but allow it to fire when the combo box is changed?
Thanks in advance for any help or suggestions you provide........
I am trying to find out a solution to implement save functionality after the values in the ag-grid is changed.
I have an angular2 ag-grid with almost 100 columns but only 4 columns are editable. And on click of a save button on my web page i want to post only the changed values if any by the user, to the database. Is there any event which i can use to identify changed rows in the grid? Or any other suggestion to implement such scenario?
I looked at rowValueChanged and cellValueChanged event, but these event will trigger after every change? I need to get the values only after the user hits save button.
I would like to reject the selection of a row in a datagrid based on the state of a form. If the form has fields with changed data, I would like the row selection to rejected.
Is there an event I could trap (before selection) and cancel or do I have to implement the logic myself?
You can either use a SelectionChangeHandler on your SelectionModel (it gives you an object which was selected, and you can unselect it), or you can use the CellPreviewHandler on your DataGrid (it gives you a row which was clicked - event.getContext().getIndex() - and you can unselect it in your SelectionModel).
The choice depends on what you want to do after the event: you have to do something obvious in your UI so that users are not confused why clicking on one row selects it, while clicking on another row does not. For example, you can change the background color of unselectable rows as soon as you render your DataGrid, and then show an error message when the wrong row is selected.
I've added a FilterForm with GoAndClear buttons to an AjaxFallbackDefaultDataTable. The filtering is working fine except for refreshing my table. I have a dropdown that changes the number of rows to show which does a target.addComponent(my AjaxFallbackDefaultDataTable) which doesn't reload the data but refreshes the. If I use this after I click a Go or Clear button then the table shows the proper rows, item count, and page links.
How can I handle Go and Clear clicks on my FilterForm to update my AjaxFallbackDefaultDataTable?
In the onsubmit method for the filter form just call .renderComponent() for the table.
I'm currently looking for a way to provide the user with being able to select multiple items from a collection of values.
I know this is done in the mail app whereby you can go into the edit mode of a folder and select multiple items by clicking on the circle on the left hand side.
What I'm unsure about is how this is achievable. Is anyone familiar with how to reproduce such functionality?
Thanks,

The easiest way is this:
Provide a UITableView with all values the user can select.
Keep a mutable array with one object (e.g. an NSNumber) per table row to store each row's selection state.
In tableView:didSelectRowAtIndexPath:, toggle the selection state in your array for the tapped row and set the tapped cell's accessory type to checkmark or none, depending on the selection state.
