How To Update Dynamic Table In Database Through Dynamically Generated Text Box

I am creating a dynamic database table, inserting some records in dynamic table and generating update command dynamically. (This part is running ok)

Code:
// Create Table
public void createtable()
{
string sql = "CREATE TABLE " + txtTableName.Text.Trim() + "(" + "InfoCode nvarchar(MAX) NULL, UserName nvarchar(MAX) NULL, Mobile nvarchar(MAX) NULL, Email nvarchar(MAX) NULL";

[Code] ....

And in another page i am displaying the list of all the dynamic database tables. Here user selects table from gridview and the data is displayed to him in dynamically generated HTML Table with Dynamic textboxes. (This part is also running ok)

Code:

// Display data
protected void getTableInfo()
{
int RowNo = 0;
string NotCmd = "Select * From NTL Where InfoCode = @InfoCode";

[Code] ....

Now the problem is how to update the record in database through this dynamically generated html table and texboxes. When I run my dynamically generated update command, all the dynamic controls is lost in postback.
