Pan Li commented on FLEX-35224:
-------------------------------
1 Peter, I think I still need to create PagingDataGrid because there is no
place to put overriding of beads, some of them can only be in css, for example
DataGridModel crush in <js:beads/>
to override the css I think it is better to have a new tag and set its default
in css, because it is confusing to override the needed beads in client code
using the custom control
{code}
js|PagingDataGrid
{
IDataGridPresentationModel:
ClassReference("org.apache.flex.html.beads.models.DataGridPresentationModel");
IBeadView:
ClassReference("org.apache.flex.html.beads.PagingDataGridView");
IBeadModel:
ClassReference("org.apache.flex.html.beads.models.PagingDataGridModel");
IBeadLayout:
ClassReference("org.apache.flex.html.beads.layouts.PagingDataGridLayout");
background-color: #FFFFFF;
border-style: solid;
border-color: #222222;
border-width: 1px;
}
{code}
2 I have another problem:
I need to override DataGridPresentationModel by
{code}
js|DataGridColumnList {
IDataProviderItemRendererMapper:
ClassReference("org.apache.flex.html.beads.PagingDataItemRendererFactoryForArrayList");
}
{code}
or declare PagingDataItemRendererFactoryForArrayList as a tag in
basic-manifest.xml and
{code}
<js:PagingDataGrid id="dataGrid" pageSize="2" x="20" y="30" width="600"
height="300" change="dataGridChange()" rowHeight="30">
<js:beads>
<js:DataGridPresentationModel/>
{code}
are there some method to override these beads instead of asking code using the
control to carefully put these overriding correct?

for updating items dynamically, since we are other requirements on data grids
and Santanu are working on making datagrid avoid full recreate on data
changing. I think I better leave it for later improvement.
