Post back problem for dynamically created datagrid textbox columns

Hi All,

        I have a datalist and in each row of the datalist I have a textbox, two datagrid and two command button. The binding of the datalist working properly and it's populating with the database records for the datagrid1.

        If the user clicks the 1st command button then I am generating rows and columns for the 2nd datagrid based on the textbox value as row and columns based on the 1st datagrid.

        Now I created the columns dynamically for the 2^nd datagrid.

         If the user clicks the 2^nd command button then I wanted to run a algorithm based on the values entered in the 2^nd datagrid.

 Now the problem is after the postback i am not getting the datagrid textbox columns which are dynamically created.

       I know i have to create the datagrid columns again in the OnInit event. I did the same but not able to get the value for further processing. Please any one help me.

This is the control structure in my web page
