Hello Kronos, Thanks for a very detail and nice reply.I got the options clear in my mind as per your suggestions.Let me explain you bit more,the maps or the layer which we are loading in the flex container is of third party tool called "openscale". Openscale is having a drawing tool,which allows a user to click and than draw shape on the map layer. Currently what i did is that for a single session i stored the openscale draw layer into a variable and rather than redrawing ,i am readding fresh layer.
As soon as layer is drawn and press the add button the openscalelayer clears the shapes and a row is added in the .NET datagrid. Now again user draws another layer in openscale and press add so a new row is added in the .NET grid.Now the main requirement is that i need to store the layer data for each row so that when user click a row in the grid that particular draw layer is restored. Hopefully i am able to clear you more in depth.Please do let me know if you are not really clear about something. Thanks.
