Can we pass object to the Viewstate?

Hi,

ViewState is Generic Data Type.So we can store different types of objects in ViewState.
For ex: I have a data in DataTable...

DataTable dtData =new DataTable();

// Store value into ViewState

ViewState["Data"] = dtData;

// Get value from ViewState

DataTable dtResult = (DataTable)ViewState["Data"];

Even we can store class object also in ViewState (Using Properties).

Note: We cannot store maximum size of data in ViewState object.

Actually we can use any object as well in view state but best practice is not to use since the data size is huge... For that its better to go with session for large data.

Yes,we can pass object to the viewstate

[Serializable]
public class Student
{
public string firstName;
public string lastName;

public Student(string fName, string lName)
{
firstName = fName;
lastName = lName;
}
}


Because the Student class is marked as serializable, it can be stored in view state:
// Storing a student in view state.
Student stud = new Student("John", "Doe");
ViewState["CurrentStudent"] = stud;
Remember, when using custom objects, you'll need to cast your data when you retrieve it from view state.
// Retrieve a student from view state.
Student stud = (Student) ViewState["CurrentStudent"];
