Question

Get value of selected item from dataGrid component

Asked by: liltyga

Hi,

I have a datagrid that is pulling data in dynamically from a database. There are three fields of data that are being queried, and what I need to do is check if one of those fields equals a certain criteria, and if true, make the button selectable.

Basically, I would draw out the desired functionality like this:

dg_someData results:

field1       field2       field3
------       -------      -------
id1          title1        typea    <------- if field3 = 'typea', btn_select enabled = true; else btn_select enabled = false
id2          title2        typeb
id3          title3        typec

        [btn_select]

Can anyone help me out and let me know how I can determine the value of the data in 'field3' above, for dg_someData, and enable the select button if the selected item matches the criteria?

Thanks in advance!

If with "button" you mean the whole row, then there's no property to do that (datagrid.selectable is a global property). You should create a custom cell renderer...

I got it to work, and am posting the solution in case it is helpful, or someone knows of a better way to do it.

In the actionscript of the dataGrid component itself, I have the following:

on(cellPress) {
      trace("parent status is" + selectedItem.Status);
      
      if (selectedItem.Status == 'typea')
      {
            _parent.btn_select._visible = true;
      }
      if (selectedItem.Status == 'typeb')
      {
            _parent.btn_select._visible = false;
      }
      if (selectedItem.Status == 'typec')
      {
            _parent.btn_select._visible = false;
      }
      
}

You are making it invisible after pressing on it?

 

by: liltygaPosted on 2005-05-17 at 00:10:57ID: 14016503

only if the criteria is not equal to 'typea' data  - they shouldn't be allowed to submit an edit request for the other values
