The error "Object reference not set to an instance of an object" in ASP.NET usually occurs when you are trying to access a member or property of an object that is currently null. The most likely reason for this error is that the grdvwTransactions object is null, meaning it has not been instantiated or initialized before you try to set its AllowPaging property. If your GridView is defined in the markup (aspx file), ensure you have an entry like this: If your GridView is dynamically created in the code-behind (C#), ensure you have code that creates and assigns the object: GridView grdvwTransactions = new GridView(); gridview.ID = "grdvwTransactions"; // Additional settings and data binding could be done here.

To resolve this issue, you need to ensure that the object is properly initialized before accessing its properties or calling its methods.

Hi, In ASP.NET applications, postbacks can often cause issues, especially when it comes to refilling data sources and validating the data. To handle this, you can repopulate your data source and perform validation checks again after a postback...
