Grid Teaser

[Steve Wood]

I did some work on my Shopping Cart last night. I wanted to add in Freight as part of the checkout total. Because I like to torture myself, I decided it MUST go exactly under the Grid Total, and then provide a Grand Total with Freight added.

See image one; that is how a Grid normally looks if you include a couple Summary Values, Total and Count in this case. But there is no option to include ad hoc item such as Freight and Grand Total (see image two).

So the teaser is, how did I get those new rows and dynamic values there (see image two)? There must be a few ways to do this, so I thought a teaser might be an interesting way to explore.

Hi Steve,

You probably changed the label of one of those summary value labels to FREIGHT and inserted something like: alltrim(str(23,250,2,",")) at the display format for that field.

see PIC.

Re: Grid Teaser

Nope. The freight value is dynamic from a table based on a pre-defined carrier* and the Grand Total is a calculated value of Total plus Freight. The "3 days" text just after the word Freight is also dynamic based on the selected carrier and their specific delivery guarantee. If the shopping cart is empty, the Freight and Grand Total rows disappear.

*Eventually it will be based on weight and selected carrier, but so far just one value per carrier.

Re: Grid Teaser

I'd probably try first by building the string to be inserted, then stritran() to finish the job.

So that's my guess.

But because you put this up here, I'll bet you found an even more clever way to do it, so my guess is my guess is wrong. Right?

Re: Grid Teaser

Right.

First I added two Summary Values that I expect I will never use, First and Last, as shown in image 1.

Then I looked at my page in the browser, found the HTML string that defined those columns in the output. It was:

First&nbsp;</td><td class="SunsetDataTD" style="text-align: right;" >449</td>

That string will always be the same except for the dollar amount at the very end.

Then in the A5W page, added the following code. This code a) creates values for Freight (frt) and Grand Total (gttl). The second part of the code uses stritran_smatch() to replace the string above, with my own calculated string which replaces the label with "Freight" and inserts some text from a lookup, and then replaces the dollar amount also from a lookup to a Carrier Freight table.

I have to use stritran_smatch() rather than just stritran() because it allows for wildcards and I need to represent the dollar amount with a "*" since I don't know what that dollar amount is going to be.

frt = lookup("[PathAlias.ADB_Path]\freightcost",".t.","str(Cost,10,2)+'|'+alltrim(Delivery)")
if eval_valid("cart_id")
	gttl = tablesum("[PathAlias.ADB_Path]\cart","Cartid="+quote(cart_id),"extension") + val(word(frt,1,"|"))
	else
	gttl = 0
end if

x_cart.Output.Body.Grid_HTML = STRITRAN_SMATCH(x_cart.Output.Body.Grid_HTML,"First&nbsp;</td><td class=\"SunsetDataTD\" style=\"text-align: right;\" >*</td>","Freight - "+word(frt,2,"|")+"&nbsp;</td><td class=\"SunsetDataTD\" style=\"text-align: right;\" >$"+word(frt,1,"|")+"</td>")
x_cart.Output.Body.Grid_HTML = STRITRAN_SMATCH(x_cart.Output.Body.Grid_HTML,"Last&nbsp;</td><td class=\"SunsetDataTD\" style=\"text-align: right;\" >*</td>","Grand Total&nbsp;</td><td class=\"SunsetDataTD\" style=\"text-align: right;background:#CDEB8B;\">"+str(gttl,10,2,"$(")+"</td>")

Re: Grid Teaser

Steve,

Would be intrigued if you could get this to work in the OnSummarySectionRender event on the grid itself. have tried

dim prof as n
prof=e.summaryvalues.ext.total*.2
e.htmlPrefix="<tr></tr>"
e.htmlsuffix="<tr>"+prof+"</tr>"

to no avail.

Re: Grid Teaser

Forget that, I have worked it out. This just puts the data above the grid. Would be great if it did what you achieved!!

Re: Grid Teaser

Good because I'm still up programming and probably couldn't figure it out if I tried right now!

Re: Grid Teaser

finally worked out how to use the OnSummarySectionRender event of a grid (V10) to achieve a similar effect which can dynamically add any number of additional rows as in attached. The new events make so much difference.
