Hello,
I have sorting enabled on parent and child. This works perfectly fine. then I use a dropdown's Selectedindexchanged event to get a filter on the number of rows and show me only 10 rows(So i bind the datasource again).This works fine, but if i exand teh child and try to sort it says:Object reference not set to an instance of an object.
How can i fix this ?if it cannot be fixed then how i can i disable this behavior after the filtering frm dropdown takes place?
I'm just checking if you still need assistance with the matter.
Hi dev_here,
I would need some more details about the issue you are experiencing. Can you share your code for SelectedIndexChanged where you filter the datasource and rebind the grid? Also, are you creating the bands and columns in code behind or in the markup, or you use auto-generated columns and bands?
