In a Infragistics2.WebUI.UltraWebGrid.v5.3, currently, a row is added dynamically, in cell of the row, a value is being shown. Now, i need to add a text box to the same cell and show the value of the cell in the text box. I need to do this dynamically, how can i do that?

Also, i need to add a new column dynamically in the same row and add a button to it. In the click event handler of the button, i need to interact with the database and insert the value of text box in one of the table in the database, please explain how can i do that? Please note all this needs to be done dynamically?
