I understand that this is a very common issue, I have been reading documentation on it for days, and I am about to pull my hair out over this issue. BACKGROUNDI have multiple Gridviews inside of an UpdatePanel. What is happening, is someone is importing an Excel spreadsheet, I am using OpenXML to shread the data and store it in a VB.NET datatable object. I then run all of that data through a custom validation (based on DB information) and then spit out the exceptions (errors) that occur into a Gridview depending on the exception. the max number is 4 Gridviews in one UpdatePanel (each Gridview has it's own functionality). There are two Gridviews that I am using a button to do an action using the data contained in the Gridview. Those two buttons are also located in the Update Panel, just underneath the corresponding Gridviews. Each Gridview is wrapped in an AJAX Collapsible Panel Extender. Now, when the user clicks on the button, I have a click event in the code behind where I take the information and depending on the exception that occurred, Update or Insert the DB. I loop through the rows, and if no error occurs, I call the datatable.ImportRow and pass the current row to my "Ready" table. I use a ScriptManager.RegisterStartupScript in order to display an alert box letting them know if any errors occurred. Then, I rebind the exception table and the "Ready" table. I have tried just adding an AsyncPostbackTrigger, I have attempted simply calling udpMain.Update() in the code behind, and tried both options of setting the UpdatePanel's UpdateMode property to "Always" and "Conditional".
