How to get data from dynamically created text boxes?

210 Expert 100+

I have a form where i have created the form dynamically. First i manually added a panel control to the web page. Then i added another panel dynamically and inside this panel i created tables. I have set text boxes and labels inside the table rows. I then added a button. All of these are done through code.

The problem that i am having is i can get the value from a text box with resides inside the first panel (out side of panel that is dynamically created) but i am being unable to retrive date form text box that is inside tables which is inside dynamically created panel. Please advice.

following code shows how the form is set up.

You should add id's to each table cell that you dynamically create so that you can access that control. Now you can easily use the FindControl method to find the control in each TableCell

Expand|Select|Wrap|Line Numbers

 TextBox tb = (TextBox)TableCell1.FindControl("txtNameofTextBox");

if(tb != null)

{

  tb.Text = "Something";

}
