Working with a DataGrid

[Terence Heaford]

Thanks for your idea, will have a play.

My experiments at the moment have resulted in this:

1. Place a rectangle graphic in the row template.

2. Create a column behaviour.

3. In the behaviour script there is a method "on FillInData pData”

4. pData is the value passed to the DataGrid for this column.

5. “barGraphic” is the rectangle graphic I created in the row template.

In this method as an experiment I currently have:

on FillInData pData
    -- This message is sent when the Data Grid needs to populate
    -- this template with the column data. pData is the value to be displayed.
    
   set the width of grc "barGraphic" of me to pData
   set the left  of grc "barGraphic" of me to 300
   
    -- Example:
    set the text of field 1 of me to pData
end FillInData


Currently with this method I have the text field containing pData showing to the left of the rectangle grc in the column.

This is "set the text of field 1 of me to pData”. I presume but have not tried yet that this field could be hidden by modifying the row template.

I am not sure of the actual method you are to use to achieve this, that’s why I’m currently calling it an experiment.

I presume the designers of the DG had a plan for this sort of thing but I can’t find any examples anywhere.

All the best

Terry
