I had assumed when I saw the following code in the guide: put field data into tData put true into pFirstLineContainsHeaders set the dgText [ pFirstLineContainsHeaders ] of group DataGrid 2 to tData I assumed that the data grid would function in much the same way that FileMaker does when importing an Excel file, i.e. it allows one to assign the items in the first line of the file to field names and the rest of the llines to populate these fields. That would be a reasonable behavior of dgText[pFirstLineContainsHeaders] il.e. when the parameter is true, the column headings are taken from the first line of the text field and the rest go into filling the columns. I must confess that I interpreted this code in the same way in particular, I think, because this phrase If true then the data grid will extract the first line of pText … The first line is only used to tell the data grid which columns to map the rest of the data to. If you want to create columns then you will need to set the dgProp[columns] property. That's OK for me now, Trevor :-) Might be nice to elaborate a bit in this lesson to prevent from this misinterpretation. Best regards from Grenoble André You can't really use multiple parameters when using setProp (which is what dgText is). I'm kind of fudging things a bit by treating dgText as a custom property set and pFirstLineContainsHeaders as the custom property. The truth is we still don't have access to a very expressive syntax when creating custom controls (which the Data Grid is one). -- Trevor DeVore Blue Mango Learning Systems ScreenSteps: http://www.screensteps.com Releasable Revolution Resources for Developers: http://revolution.bluemangolearning.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

The most likely cause is that you don't have a column labeled with Col 1 or Col 2 in the first line of the data. Therefore the data you are setting is not mapping to an existing column in the Data Grid. Data Grid's do not behave like fields in that you can just swap text in and out randomly. You should be defining the columns (using the Property Inspector or by setting the dgData[columns] property) and then assigning data to the Data Grid that explicitly states which column data goes into. The reason for this is that Data Grid columns are objects in and of themselves. They have properties that are set independently. If you want to wipe them all out at once then you first create the columns, set the column properties and then assign the data. As a side note the fact that dgText automatically creates columns for you is unfortunate in my opinion. This behavior was requested so that someone could just set the text of the Data Grid and see instant results. While that may be beneficial for instant gratification I think it just causes more confusion then anything in the end. The Data Grid isn't meant to be a quick and dirty means of displaying data but rather a means of displaying data with lots of control over the visual elements used to display that data. -- Trevor DeVore Blue Mango Learning Systems ScreenSteps: http://www.screensteps.com Releasable Revolution Resources for Developers: http://revolution.bluemangolearning.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

If you want to wipe them all out at once then you first create the columns, set the column properties and then assign the data. As a side note the fact that dgText automatically creates columns for you is unfortunate in my opinion. This behavior was requested so that someone could just set the text of the Data Grid and see instant results. While that may be beneficial for instant gratification I think it just causes more confusion then anything in the end. The Data Grid isn't meant to be a quick and dirty means of displaying data but rather a means of displaying data with lots of control over the visual elements used to display that data. -- Trevor DeVore Blue Mango Learning Systems ScreenSteps: http://www.screensteps.com Releasable Revolution Resources for Developers: http://revolution.bluemangolearning.com Trevor (and Andre.Bisseret), Thanks you for the very thoughtful reply(s). It is heartening to see something defended by its parent. My sincere apologies for treating your offspring in such a quick and dirty fashion :-) I'm sure I will appreciate the richness of this new Run Rev object in time--see below. FIrst to satisfy my quick and dirty needs, I find that the following works well to get data displayed in a data grid field: on mouseUp put field data into tData --Tab delimited text --The first line of tData contains the column names put line 1 of tData into tHeaders replace tab with cr in tHeaders set dgProp[Columns] of group DataGrid to tHeaders --Thanks to Andre for this line. set the dgText [ true ] of group DataGrid to tData end mouseUp Now to reinforce your point about the richness of this more complex object: In another context, I would like to be able to click on the first column header and have it sort the grid by the LAST word of each in the first column. Is it possible to access (and modify) the script that the column headers runs? Thanks again for nursing us through the infancy of data grids.

I should probably add that to a lesson somewhere...

Re: Newbie Data Grid question
I noticed that the column headings aren't automatically set when you load the datagrid with data. I manually set the column names and then when I loaded the data in (using a different method with ) I put in the column headings exactly as I had manually named them. It turned out that later, when taking data out of the datagrid, I did it using those column headings. I was surprised that when you load the data grid it doesn't change the column headings. But it works perfectly otherwise. On Sun, Dec 13, 2009 at 2:53 PM, James Hurley jhurley0...@sbcglobal.netwrote: I am just getting into data grid fields and can't find first base.

Does your columns already exist ? Thanks Andre, Yes the columns already exist. If I set pFirstLineContainsHeaders to false, the field is populated with data but the columns are set to Col 1, Col 2 etc. If I then set set pFirstLineContainsHeaders to true (with the columns already set to Col 1, Col 2, etc.) the columns remain unchanged but the body of the text is empty. I did download the Manual. That is where I got this information from. Very perverse.
