[CLOSED] GridPanel RowSelectionModel
Hello,
I'm having a problem with the row selection model and postback events, please see the simplified example which demonstrates the issue and the replication steps below.
Example.aspx:
1. Load page
2. Select Timothy
3. Click the Edit button; notice the label returns "You selected: 0"
4. Use the next page arrow on gridpanel
5. Select Geoffrey
6. Click the Edit button; notice the label returns "You selected: 0" [wrong]
7. Use the next page arrow on gridpanel
8. Select Vladsch
9. Click the Edit button; notice the label still returns "You selected: 0" [wrong]
Cheers,
Timothy
