Re: Getting Started with DataGrid and another datagrid form question
Dear Douglas, Thanks for your interesting feedback about your attempt to use DGH for the first time, with creating a datagrid form. All the properties for customizing the datagrid apart, I've created the form template area (the way to custom the content of a row with controls such as image, buttons, etc) with the following objectives: - in the standard way to customize a datagrid template, we have to open the row template group inside the template card. In DGH all this group is copied inside a "visual" area we can manipulate - when dropping some controls in the template area, with the datagrid, you are alone with the required script for managing all these controls. DGH, at the condition to respond to the right dialog, is building a minimal script depending of the kind of controls you added. Unfortunately this is difficult to cover all the needs, because they are all specific depending of the developer and what he want to do. But at least the goal of the installed script is to give you the keys and philosophy to understand what it is required for the controls.For a button, how to perform an action, for a checkbox, how to check or uncheck it, for an image how to display it, to click it, etc - one of the recurrent difficulties for users was to understand the datagrid rows remains empty until you have populate it. And because it is empty you will never see the beautiful button or image you have added if you have not at least a row data. This is why in DGH, upper the template area, we have a datagrid preview, to see immediately the control we have added. Your comment make me realize that it is not enough when you are beginning with form template. One of my unexploited idea was to add kind of presets template with for example a text on the left and four checkboxes on the right, etc so the developper could start with ready to use templates to add to his datagrid. The problem of the approach is covering needs, I can't anticipate. What might have you expected from DGH in this task? More tutorial explaining how the template area is working?, more lessons?, contextual help in DGH to help you to start? Something else? Feel free to expand, I'm always interested in approachs or ways I could try to implement in the goal to improve DGH. Thanks in advance.

Re: Getting Started with DataGrid and another datagrid form question
I concur with Brahmanathaswami that, in particular, datagrid forms (I haven't worked with tables (yet)) are very finicky with regard to scrolling. I still would greatly appreciate some help with a recently submitted message to this group, Subject: datagrid form question Once you play around with a grid enough, it becomes clearer on what you can and cannot do. Regarding DGH v2... during my initial foray into datagrid forms (very recent, by the way), I was hoping that DGH v2 would be the panacea for the initial confusion regarding datagrids. Alas, it is likely a fine tool but, from my perspective (as many aspects of LC), it may be most effective once one has mastered the fundamentals of datagrid construction and usage. I downloaded the trial version and will go back to it ASAP now that I am over that initial learning hump ... with A LOT more to learn, I'm sure. It would probably be worthwhile to read through my two posts under " datagrid form question " to consider what I discovered with regard to scrolling... hopefully, I've made the explanation clear enough but if not, I'd be glad to expand on the subject.

re: datagrid form question
I realized belatedly that I didn't do a very good job (at all) of describing what one of the row's in my grid looks like... it may be relevant to a solution. Each row has 1 checkbox, 3 fields and 2 buttons. One of the buttons (the one I need assistance with), named "Query" calls a "tsnet" function to query a remote WiFi module (esp8266) to return the status of one of the IO pins on the wifi module. Works like a charm on ALL rows, scrolled or not... becuse (I reckon) the button is actually *IN* the grid, so there's no issue with the group name.. it is always "me". I also want to "automate" the queries (there are 8 such wifi modules involved). So I have a button outside of the datagrid which selects each row of the populated datagrid and sends the "mouseUp 1" message to the datagrid (described in my previous message under this subject) It is THAT loop which manufactures the Row Template group names. It is THAT loop which has to know (at this time) which line/row it needs to "wrap" the group name back to "...0001" Douglas Ruisaard Trilogy Software (250) 573-3935 ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
datagrid form question
Using LC v8.1.9 on Windows 7 pro "Where" do I send a "mouseup" message on a datagrid form which has scrolled lines... i.e.: send "mouseUp 1" to I know it sounds like a ridiculously simple question (and likely is) but a datagrid form seems to create a "Row Template" group for each populated row... i.e. "Row Template 0001", "Row Template 0002"... etc. UNTIL it reaches a row which is outside of the visible rows it then starts to create "duplicate" templates. For example, if there are 6 populated rows and the DataGrid is sized to only show 3 rows at a time, upon the initialization of the Datagrid, the Row templates groups are named: row 1: "Row Template 0001" row 2: "Row Template 0002" row 3: "Row Template 0003" row 4: "Row Template 0004" row 5: "Row Template 0005" row 6: "Row Template 0001" row 7: "Row Template 0002" row 8: "Row Template 0003" this is demonstrated by putting a "put me" in the Behavior Script within a MouseUp handler. So... the "simple" issue is that if I "manufacture" the Row Template name based on the row to which I want to send the "mouseUp" command it works perfectly for the "visible" rows... even the next 2 rows (which I have scrolled into view via: set the dgHilitedLines of group "DataGrid 1" to y put the dgIndexOfLine[y] of group "DataGrid 1" into x where "x" and "y" are throw-away variables ... which scrolls the appropriate row into view (for some reason)) ... if I try: dispatch "ScrollLineIntoView" to group "DataGrid 1" with pLine" ... my row data doesn't populate properly ... which I may ask about another time. BUT, for the 6th and subsequent lines I have to "wrap" the group names according to the pattern above. i.e. for the sixth line, I manufacture "Row Template 0001", etc. Since this "wrap-point" changes based on the "amount" of the datagrid I "expose", this doesn't lend itself to a very nice supportable project. No doubt I'm approaching this wrong but I'm trying to teach myself datagrids and it's a struggle for this old brain!
