Conversion problem

Mahesh Babu

This is my code.

GridView1.DataSource = Session["Seats"];
DataSet ds3 = new DataSet();
ds3 = (DataSet)GridView1.DataSource;

When I am trying to convert gridview to dataset I got one error .
i.e
Unable to cast object of type 'System.Collections.Generic.List`1[System.String]' to type 'System.Data.DataSet'.

How to solve this problem.

It looks like 'Seats' in your Session object is a List and so quite a bit of work may be needed to get it into a DataSet. In order to help you further, we'll need answers to the following questions:

What tables does your DataSet contain, what columns do those tables have and what are the types of those columns?

What is the format of each string in the List and how does this map to the columns in the table or tables?

Whatever it is that you are trying to do, it is unfortunately not as easy to do as that.

What is it that you are trying to do? Why do you need to do that conversion?

Also note that there are many great articles in this web site that can help you.
