I am still having problems with a datagrid. As I said before, this is my
first attempt at an ASP.Net (or any asp) application.
I have a grid that is bound to a dataset. This grid is populated in the
Page_Load event. The grid allows paging and itr works correctly.
I have another grid that is also populated by a dataset. This dataset is
filled as the result of a stored procedure and a user defined parameter. The
dataset is filled in a button_Click event. At first, when the button was
clicked, the grid would populate and be visible. However, whne the next
event was pressed I could see the progress bar moving but the data in the
grid did not change.
After much work, including deleting the grid and building a new one, the
grid is no longer visible. I even move the fill to the page_load event and
gave the proc a parameter value. The dataset fills but, the grid is not
visible.
What I am doing should be possible, isn't it? I am trying to follow examples
in a book but, I cannot get this to work.
I will be more than happy to show as much code as would be helpful.
I cannot tell you how much your help would be appreciated.
Thanks,
Roy 2 938
This post looks strangely familiar. The dataset only makes an appearance if
there is data to be displayed. Your code should be like this:
if(DataGrid1 != null && DataGrid1.Tables[0].Rows.Count > 0)
use the data set
else
display a message informing the user that there is no data
