  Dynamically adding rows and cells to the table.....

  Sep 30, 2011 04:32 PM|LINK

  Hi,

  I have a Table control, where I add controls to a new the cell, add this new cell to a new row and add this new row to the table.

  Page renders fine. How can I have viewstate so that I don't have to call sql server again, get all the values, create new cells, rows and then add to the table?

  How can I retain what has been added to the table, instead of re-creating the table all over again evertime there is a postback.

  Thnx

  Hi,

  You must recreate the table in each postback, because the table content is created in each postback, then the table haves a  similar behaviour to the dynamic controls... they need to be recreated on postback.

  so that I don't have to call sql server again

  you can save the datatable in a session object or viewstate or other option.

  Any doubt, post your comment.

  Yes Mavrick , calling SQL server by queries and update table is needed in each postback. because you can't know when the user will leave the page except if there is a save button to confirm the operation.

  In this case you can use an Updatepanel.
