How can I stop ASP .NET 2.0 caching my datagrid?

Question

I have a form that I am using to post data to a database table and a gridview on the same page that is displaying the data.

When I post the data, the grid view is not updated until I manually reload the page.

I know that the whole page is not being cached becuase I have printed the current time and this changes when the form is submitted.

Answer 1

You see the page is not being cached, but the data is being loaded from ViewState. Make sure you refresh the GridView after updating the DataSource.

private void Page_Load( ... ) {
if(!Page.IsPostBack() {
BindGridView();
}
}

private void BindGridView() {
//set DataSource of your GridView
//call the DataBind() method of your GridView
}

//call the BindGridView() method whenever you update your DataSource


Hope this helps.

Answer 2

Make sure the method that populates the GridView is being executed when the page posts back and not just on first load.
