Whatever Rajesh told in Solution 1 that is perfect for you. But there is one problem in that solution, "Where to create the grid?". If you'll create the grid in Page_Load or in other events you may loose your viewstate of grid in each and every event. You need to take care about that also.

My suggestion:
Better create all dynamic controls in Page_InIt event. This will bypass the issue of ViewState not loading consistently. Controls will be accessible, but viewstate not yet applied to them.

Refer ASP.NET tips: Golden rules for Dynamic Controls[^]

These are some steps you need to follow in order to generating dynamic GridView.
I. Create a GidView object.

C#

GridView gridview = new GridView();

II.Take a PlaceHolder in your page and write code for adding the GridView to PlaceHolder.

C#

PlaceHolder1.Controls.Add(gridview);

III. Now write the code for retrieving the value from database.

C#

SqlConnection con = new SqlConnection(connectionstring);
SqlCommand cmd = new SqlCommand("select * from Emp", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);

IV. Now bind the DataSet object with gridview.

C#

gridview.DataSource = ds;
gridview.DataBind();

That's It.
