Udayms, set the last selected index to a variable, launch a modal popup, refresh the grid, when the results come back, set the selectedindex to the variable you saved it to.

private var lastSelected:Number;

function refresh()
{
   // your data call
   lastSelected = yourGrid.selectedIndex;
   PopUpManager.createPopUp ( this, SomeWindow, true);
}

function onYourDataServiceDone()
{
   removePopUp();
   yourGrid.selectedIndex = lastSelected;
}

Tony, if you use the Embed metatag (or @Embed in the Image source), that'll be a linkage. You can make a cellRenderer class, just like you do in Flash for the DataGrid. Then all rows will use the same asset. Both; try Flexcoders.

Hi,

Sorry to be off topic too. I was wondering what good resources were out there for Flex development. I currently want to find out how to embed an asset into my Flex application and display it in a datagrid when needed. I could go with the load call. But I don’t want to have to request that asset for each row in my datagrid. I kind of want to do something like linkage in Flash.

Cheers
