The problem of passing the value of a column in the DataGrid through Session when clicking

天风鲁伊

Thank you upstairs, let me give it a try

天风鲁伊

There are many command events, ItemCommand, EditCommand, etc., which event should be placed in?

天风鲁伊

When binding data, it is executed in a loop. Assigning a value to session["LoginName"] in the loop is certainly not what you need. Prevent the command event and assign the loginName value of the current line to the session after clicking.

No, the command event does not respond to click events

OnItemCommand
achievable

天风鲁伊

Suddenly understand, give it a try

Oh sorry, indeed, I used an imagebutton to click directly, it does not trigger OnItemCommand

天风鲁伊

No way, add a button bar, so it becomes very easy

Thank you all for your kind help! I hope someone can solve this problem in the future

onclick is a client-side event, it does not go to the server-side, it does not return, so no background event is triggered

terrysx

But if you are not afraid of trouble, call the script and then call the background Ajax method, maybe you can assign a value to the session
I don’t know how to assign a value to the session in the foreground.

Oh,terrysx, thank you
