Button only allows one click
-
Ok i have a button on my webform. When i click it it is suppose to open a database and read from it. It does this and returns the first value into a text box. Now when i click it again i want it to return the second value of that database, but it does not, the text box stays showing the value of the first click. Here is my code
Private Sub btnnext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnnext.Click createreader(sql) myreader.Read() descrip.Text = myreader.GetValue(0) Page.Response.Write(descrip.Text) End SubPlease any help would be much welcomed. thanks -

From your code, I don't see how you're doing that. In the old days you would do it using a hidden input field (or the Session - yuck). These days you can use the
ViewStateproperty. Regards, Alvaro
