posted February 13, 2005 12:55 PM Would it be possible to and how difficult would it be to extend the LiveControls to add application specific functionality? Basically, we have created our own Data Grid and Data Grid Columns and I would like to add your callback functionality to them. The controls are pretty basic really, they mostly just abstract the Data Binding, Validation, and Updating. Some of the columns combine multiple controls into a single column. Also, we have created our own combo box and are using some other 3rd party date and numeric controls. Is there any way to add callback functionality to them? |

posted February 14, 2005 10:02 AM Probably the best approach would be to use the LiveCallback control. See the docs (Advanced Topics --> Creating Custom Callbacks with LiveCallback). Also, any of your controls that you add the "LiveControlUpdate=true" to will automatically be updated from within a callback if changed. For more information on this, see the docs (Optimizing Performance --> General Performance Tips --> Only update Microsoft/3rd party server controls when necessary) |
