Hi
I have created a DataGrid which has an overriding setFocusedCell()
method (copy and pasted from DataGrid.as), with the following
changes.
1) I had to remove a reference to 'roundUp' as the compiler didnt
like it.
2) I want my cellEditor to be a ComboBox rather than a TextInput. So
I replaced the following line
cellEditor = listContent.createClassObject
(mx.controls.TextInput, editorName, EDITORDEPTH, {styleName:col,
listOwner:this});
with
var dp = [s1, s2, s3, s4];
cellEditor = listContent.createClassObject
(mx.controls.ComboBox, editorName, EDITORDEPTH, {styleName:col,
listOwner:this, dataProvider:dp, editable:true});
The problem i have is, the combobox dropdown doesnt close, when you
click elsewhere on the Datagrid.
There is no problem if combobox.editable = false (initial parameter
passed to craeteClassObject)
I appreciate any help. Code is below.
BTW. I dont want to use a custom cell renderer. This is only a
simple example to highlight my problem.
Regards
