How to get rid of the you must first save or cancel your changes warning?

[richardurban]

I use a grid with some xbasic code on a button to add items to a shopping cart. There is a quantity field. If someone makes a change, like entering a quantity and then changes their mind and then wants to go to another page, they should not get a warning. I want to over-ride or turn off the warning to save or cancel changes. Anyone know how to do this? I found several posts about this over several years, but no answer.

Did you try the grid method {grid.Object}.resetGridPart() ?

That doesn't work. I placed that code on the Client side CanPageNavigate event. It causes a "are you sure you want to cancel all changes" message even when no changes have been made. When you do make a change without saving it you still get the "you must first save or cancel your changes" message. It would be great if there was just a feature to disable these message. I will ask alpha for that enhancement.

If you want to discard the users changes on the Detail View part of a grid without displaying the "You must first save or cancel your changes" message then you can do this:
Go to Client-Side Event, "canDetailViewClose", and put in:

{Grid.object}._detailViewIsDirty = false;
return true;

I believe, if you wanted to discard changes in an editable grid when user trys to navigate away from current page then you go to the client-side event, "canPageNavigate", and put in:

{Grid.object}._isDirty = false;
return true;

I don't know if the above is the recommended way to do things or not, but I figured it out by tracing a javascript alert() statement that I placed in the "canDetailViewClose" event. That led me to the following a5 Javascript library function that displays the "you must first save or cancel.." message:

_confirmAction: function() {
if(this._readOnly) return true;
var silentFlag = typeof arguments[0] != 'undefined' ? arguments[0] : false;
if(this._isDirty) {
if(!silentFlag) A5.msgBox.show(this.messages.t_dirtyRecordWarning,this.messages.dirtyRecordWarning,'O',function() {} );
return false;
} else if(this._detailViewIsDirty) {
if(!silentFlag) A5.msgBox.show(this.messages.t_dirtyRecordWarning,this.messages.dirtyRecordWarning,'O',function() {} );
return false;
}
return true;
}

If you want to save the changes automatically then I suspect there are grid and detail methods you could call from within the canDetailViewClose and canPageNavigate events.

If you want to stop the user from navigating away from the page then put a 'return false;' in the event handler.

Simple: On the genie for opening a Grid Component, UNCHECK the property: Warn before closing if grid in window is dirty

Yep, that was too easy, Carol. Maybe it does not matter, but that option does not appear unless the Target is set to "Window".

Here is the solution from Selwyn Rabins:
then you can overwrite the pageNagivate function by adding this code to the grid's onGridRender client-side event:
(as you can see i have simply commented out the line that ask for confirmation)

{grid.object}.pageNavigate =  function(target) {
		if(!this._executeEvent('canPageNavigate',{target: target})) return false;
		var part = typeof arguments[1] != 'undefined' ? arguments[1] : 'G';
		var additionalData = typeof arguments[2] != 'undefined' ? arguments[2] : '';

		//if(!this._confirmAction()) return false;
		this._executeEvent('beforeAjaxCallback',{ajaxEvent: 'PageNavigate'})
		this._submitLow('PageNavigate',this.gridId,this.ajaxURL,'__targetPage=' + target +'&__part=' + part + '&__dvWindow=' + this._detailViewWindowState +'&' + additionalData); 
		this.clearDetailViewGlobalError();
		return false;
}

Okay, so my post # 4 does not have the method calls to clear global errors, like Selwyn's. Looks like there are two methods for clearing global errors, one for Grid part and one for Detail part:
{grid.Object}.clearRowErrors(); '-- For Grid
{grid.Object}.clearDetailViewGlobalError(); '-- For DetailView
