Hi,
I am working on a project in which on selecting a drop down list item the values from the database should appear in the respective two text boxes.
But, alongside I am placing an image which is actually getting created based on the two values. Now on selecting the next dropdownlist item there is a page refresh and the placed image dissapears.
How to I avoid the page refresh keeping in mind that the fields from the database must get displayed on the page in the two fields on select of drop down list.
Kindly help!
thanks...
In my case, there exists a table in which there are two halfs, the left has text boxes n a button n to the right side of the table the image appears.

Hi,

Put the piece of code which you want to refresh into UpdatePanel and put the image outside of update panel.

Or you can regenerate the image from the code behind again.

Refer below link to work with update panel.

thanks for the reply,
on setting AutoPostBack to false in dropdownlist the text box items doesnt fetch the database items. I guess page refresh is necessary to fetch the database stored items.
is it?
