Setting Default value in Grid video M8

VIDEO-M8

The Grid allows you to enter new records directly in the Grid part, or in the Detail View part. The Grid builder allows you to specify default values for fields in new records. This can be done by either specifying the field's 'Initial Value' property, or by specifying code in the 'onInitialValueCalculate' event.

In the case where data entry is done in the Grid Part (as opposed to the Detail View), the issue with the 'onInitialValueCalculate' event (which is a server-side event), is that it is only called once, when the Grid is initially rendered. So, if you enter a new record and then save that record, the event is not called before the next new record is displayed. This video shows how you can save the value of a field that was just entered inside the Grid's 'stateInfo' object, and then use the 'afterRowPopulate' event to retrieve that value and use it as a default in the next new record.

Note: The .setValue() method is not used to set the value of the field in the new record row because this would cause the new record row to go 'dirty'. Instead we get a pointer to the element and then simply set its value property.

Tested this code getting script error and does not work anyone see a problem with it? I copied I thought properly from the video?

Properties TAB > afterrowpopulate:
if(e.rowNumber == -1 ) {
var newvalue = this.stateInfo.defaultValue_CustomerId;
var ele = $('{Grid.ComponentName}.V.R'+e.rowNumber+'.CustomerId')
ele.value = newvalue;


Server Side events:
Afterinsertrecord

dim js as c
dim ar as p
ar.defaultValue_CustomerId = e.dataSubmitted.CustomerId
dim json as c
json = vartojson(ar,.f.,.t.)
js = "{grid.object}.setStateInfo(" + json + ") ;"
e.rtc.A_AjaxResponses[].text = js
e.rtc.A.AjaxResponses[..].id = 1

end function

I have done this and it works ok for me.

It looks like you may have forgotten to close your if statement as well as a missing semicolon,

if(e.rowNumber == -1 ) {
var newvalue = this.stateInfo.defaultValue_CustomerId;
var ele = $('{Grid.ComponentName}.V.R'+e.rowNumber+'.CustomerId')[B][COLOR="#FF0000"];[/COLOR][/B]
ele.value = newvalue; [COLOR="#FF0000"][B]}[/B][/COLOR]

Frank thanks I can not believe I did not see that thats why this board is valuable.

Now that I have fixed all that I am getting this error code. Is this because I am on a version below that functionality?
Error executing afterInsertRecord event handler: command: e.rtc.A.AjaxResponses[..].id = 1 Unexpected internal Alpha Five error.
Please send the following information to technical support at Alpha Software.

Re: Setting Default value in Grid video M8

I also cannot get this to work.
My code is as follows:
Server side
AfterInsertrecord

dim js as c
	dim ar as p
	ar.defaultvalue_distrib = e.dataSubmitted.distrib
	dim json as c
	json = vartojson(ar,.f.,.t.)
	js= "{grid.object}.setStateInfo(" + json + ");"
	e.rtc.A_AjaxResponses[].text = js
	e.rtc.A_AjaxResponses[..].id = 1

Client side
afterRowPopulate

if(e.rowNumber == -1 ) {
	var newvalue = this.stateInfo.defaultValue_distrib;
	var ele = $('{Grid.componentName}.V.R'+e.rowNumber+'.DISTRIB');
	ele.value = newvalue;
	
}

The field that is supposed to be populated in the new row is saying "undefined".
I also see that in the e.rtc.A_AjaxResponses[].text = js in the debugger that the json statement is being truncated, but I do not know why. Maybe this is why it is not working.

Re: Setting Default value in Grid video M8

javascript is case sensitive, so it is no surprise that your code does not work.

you set a variable called 'defaultvalue_distrib' in the stateInfo object, but then you try to read a variable called 'defaultValue_distrib' in your afterRowPopulate event.

there is no such variable and hence the value inserted into the field is 'undefined' which is correct.

if you fix your code (use either uppercase 'v' or lowercase 'v') so that the variables names are the same when you set and read them, your code will work.

Yes, thanks so much Selwyn. It works perfectly now.
