i want to submit the values of this dynamic textbox on button click.
The control which you are creating dynamically, you need to created before Page_Load(), other wise, it will not able to maintain the View State Data or will not load the Postback Data.
If you deeply look inside ASP.NET Page Life Cycle, Before Page_Load(), there are two different methods calls. 1) LoadViewState() and 2)LoadPostbackData().
So, if you create any control on Page_Load(), or after that it will not able to load the data.
So you need to create such control either in Pre_Init() or Init() method.
Though there are workaround to add the Control which are created after page_load into Control Tree for maintaining viewstate and Postback, using Catch up. I am not discussing that over here. 
Hope this will help you in longer run

Use Page_Init or OnInit for adding dynamic control otherwise you need to manually maintain the view state.

In ASP.NET 2.0 you can use Page_Init or can override OnInit.

you seem a little thick. You are posting the same question day after day. Day after day, you get the same answer, which assumes that you're using .NET 3.5. You know you're not, so you need to make that clear. In any case, every day, you're being given the same information. Are you just blindly asking this day after day, without ever writing any code ? Post the code you've written, so we can help you progressively, instead of people giving you the same answer, every day.

What does it mean ? Are you getting any error ? or what ?
You are talking about Hosting on IIS or Running your Application From Visual Studio ?

Yes ! That's why I asked you the question, what is the problem if you are hosting on server, you have to give Write Access permission to that folder where you are uploadinf the file.

Always rememebr this rule of thumb:
Everyapplication can have one and only one Main function.
Search in your code, it looks that there are multiple main functions are defined.

This has nothing at all to do with ASP.NET. You want the C# forum. You should work through a basic book rather than trying to copy code off the web.

It is not working. there are more than one textboxes and user can enter value more than one textboxes according to colmuns
|

You can change filter expression for Select of dataset as per our values.
|
|
|
|
|
But it is giving error object refrence is no set an instance in secondline while colmun is ok and also creare memory for dataset
DataRow[] R;
R =ds.Tables["tmp"].Select("cityname ='" + TextBox6.Text + "'");//Error
GridView1.DataSource = R;
GridView1.DataBind();
