What's the value of txtFactoryName.Text?

Inspecting querystring is very easy. Look at the browser url and you will see the querystring values there.

The url will look like
www.yourdomain.com/.../Hypertension .aspx?slno={some value}
Perhaps the value is null and that is why querystring returns null value.

In the insert statement shows all value are available and inserted successfully, but the query string return null value in the url. I want to display the query string value in the next page.

Hi,

You have called the function 'resettext();' before Response.Redirect.
I think it will clear the textbox content.

Can you please check into 'resettext();' function.
