I'd like to alter a cell's data, but only when it enters "edit" mode. There are a lot of events I can use, onSelectionByProp seems close but it's firing too often to be useful. Let's say, for instance, that I want to add '*' to a cell that has a value that is invalid in some way, but only when that cell is about to be edited. OK, it's a silly example but it's easier to explain that than what I'm actually doing.
My current approach (haven't done it yet) is to find TD.current when a cell is double-clicked and then alter the text directly. Ideally I'd like to find a "retrieve data" event and alter what's coming back from that.
You can map keyup, keydown, keypress or change event from jQuery for .handsontableInputHolder element in a page. Is a textarea in which user enter data, so this is your 'edit mode' for handsontable.
onEditBegin is a proposed event for future version.

I want to show messages in my form. I wrote them in an item's 'KEY-NEXT-ITEM' trigger.
MESSAGE ('You can not write this!');
MESSAGE ('You can not write this!');
But form is not showing this messages. Why?
Messages do work.
KEY-NEXT-ITEM trigger is probably not the best choice. It fires if you press TAB or ENTER keys on the keyboard to navigate out of the item. If you, for example, clicked with a mouse and left the item, then this trigger won't fire. A better choice is WHEN-VALIDATE-ITEM trigger so I'd suggest you try it. If it doesn't help, describe the problem again, providing some more details.
I got the reason! I did'nt choose console window of my form. When I chose a console window, messages appeared.
I have just started working on Kendo Controls in Angular. I have found an example here where its making use of both selectionChange and valueChange event. So, my question is what is the difference between these both and when to use them?
Thank you
Imagine focusing the combobox, pressing the down arrow a few times until you find what you want, and hitting enter to choose it. In this example, each press of the down arrow changes the selection, and pressing enter changes the value.
For the jQuery extension Jeditable, one of the parameters that can be specified is which DOM event will turn a div/span/... into a text input/textarea/...
I would like to have more than one event serve as a trigger; that is, I would like either a click event or a contextmenu event to turn a span into an in-place edit area.
Is there a graceful way to do this without forking Jeditable?
--edit--
An example of code specifying the event is below. The parameter is optional, defaulting to a regular click.
$(".edit_rightclick").editable("/ajax/save",
{
cancel: "Cancel",
submit: "OK",
tooltip: "Right click to edit.",
event: "contextmenu",
});
Calling twice, once for the regular click event with the event unspecified, and one for the contextmenu event (right-click if there are no switched mouse buttons or anything like that) does not seem to produce the intended effect of an element becoming editable in place on a click from either mouse button.
I'm taking the lack of answers so far to mean that it's impossible, or rather it would require changes to Jeditable or jQuery that would include headaches for the developer, possible code smells, etc.
It's a longshot that anyone can help with this, but here goes. I inherited a VB6 app with a Janus GridEX control. It iterates through records, and is editable. Problem is, if I edit a cell and hit the button to go to the next record, the change is applied to the next record, not the one I was editing. It's like, I need it to finish up the edit before going to the next record. I've had this sort of problem before in VC++, and sometimes you have to "KillFocus" on the control you're on or something. I just don't know what to do here. I tried sending a carriage return, since if you return out of the edit cell, it works, but sending a carriage return manually doesn't work. What's the secret?
Is your grid bound or unbound?
It's hard to tell from your description, but I imagine that if your are having this problem then it's probably bound.
As the other answer asked, is the button the RecordNavigator that is built into the control or is it a separate button? The reason I bring this up again, is that I have seen issues in the VB6 applications I support where a toolbar will often intercept and interfere with how the JanusGrid should work.
To get around this limitation, I have added the following code in the click handler of any toolbars where there is also a JanusGrid control on the form.
If jsgxYourGridName.EditMode = jgexEditModeOn Then jsgxYourGridName.Update
This way any changes are immediately applied to the current row.
If this does not help, then I have also seen problems where the recordset that is bound to the grid gets out of sync with the internal recordset in the grid. You can check this by comparing the bookmark of the grid to the bookmark of the recordset.
Ie. mrsYourRecordset.Bookmark = jsgxYourGrid.ADORecordset.Bookmark
At one point I may have also used something like this.
jsgxYourGrid.ADORecordset.Bookmark = jsgxYourGrid.RowBookmark(jsgxYourGrid.RowIndex(jsgxYourGrid.Row))
Finally you can try setting a breakpoint in the BeforeUpdate, RowColChange and/or AfterColUpdate events of the grid, to see what record the grid is really on when clicking on the button.
It depends whether the button is internal to Janus GridEX or not. If it internal then just about the only thing you can do is look at the events the control exposes to see if there a sequence that can let you know that this problem occurs. Then you can try to take corrective action by restoring the row you moved to and put the edit in the row you left.
If the button is external to Janus then you can use the debug mode to trace sequence of statement that control the transfer of focus to the next row. It could be something out of order or a side effect of the particular sequence of commands. I have run into both with different controls.
Remember that you can edit while in debug mode so you can try different approaches and test until you find one that works.
I have a form in VB6 with two combo boxes (cboCustomer and cboItemNumber). When someone selects a value from cboCustomer, I want to populate cboItemNumber with a list of item numbers relevent to the customer selected. What event does VB6 offer that I can use? I've tried _Change and _LostFocus and neither are doing what I need. I find it hard to believe that I'm having such a difficult time finding a list of possible events.
Try the _Click event. This event fires even if the control is't actually clicked on. For example, if you tab in to it and use the up/down arrow keys to change the selected item, the click event still fires.
As G Mastros says, the _Click event is the one to use, since it fires when the selection is changed via either keyboard or mouse.
If you want to see a list of all the events, then use the Object Browser (F2), and search for or browse to ComboBox. Events are shown with yellow lightning bolts in the Members pane.
