Apache – Displaying popup by clicking on cell

apache-flex

I have datagrid with populated data. When the user clicks on one particular cell of one column, the popup window has to be displayed, and also same requirement is there for another column.

I could not find how to do it for cell.doubleclick and click properties are applicable to row selection. Can any one give solution for this requirement?

Listen to the itemClick event of the DataGrid - it dispatches an event of type ListEvent that has columnIndex and rowIndex properties.

If for some reason it doesn't work, you can use a custom itemRenderer and dispatch a custom event using its listData.owner property.

I know at least two things you can use to position a popup, though there might be more.

When you place a popup you can choose in which parent component to place the popup:

PopUpManager.createPopUp(this.parent, TitleWindowComponent);

In the component itself:

PopUpManager.centerPopUp(this);

A VBox does not implement IDropInListItemRenderer. A IDropInListItemRenderer gives you the "listData" property (which is of type "DataGridListData"). Furthermore, "listData.owner" will be the DataGrid object, and "listData.rowIndex" gives you the rowIndex property.
