Be more specific. What is the trouble you are having?

Yes, it is. Read the following article: http://www.codeproject.com/dotnet/passingvaluesbetweenforms.asp[^]
You should be able to pass the datagridview object using the methods the author talks about.

Then what is? The article shows how to pass values from one form to another. You can extend this by passing the whole object from one form to the next using the same principles that Colin talks about.

I am not being harsh, but it sounds like you've bit off more than you can chew at this point.
You could always make the datagridview object be public and just grab it from the second form.

hi all,
im now doing the 'SearchEvent' using asp.net & C# on visualstudio2005,
where the user will search the event by selecting from the 3 dropdown boxes:
dropdownDay, dropdownMonth and dropdownYear.
It's suppose to query the 'start_date' from the ms access.
eg. 10-Mar-2004
im trying to write the query on it, but i kept getting the error when i run.
query:
string query = "SELECT code, description, start_date, start_time, venue FROM Event WHERE start_date = '" + dropdownDay.SelectedIndex.ToString() + " + ' - ' + " + dropdownMonth.SelectedIndex.ToString() + " + ' - ' + " + dropdownYear.SelectedIndex.ToString() + "' +";
Error message that appeared in visualstudio2005:
Syntax error (missing operator) in query expression 'start_date LIKE '%10 + ' - ' + 3 + ' - ' + 8%' +'.
i would appreciate some help on this line of code.
thanks! =D

your query is looking wrong
try this one
string query = "SELECT code, description, start_date, start_time, venue FROM Event WHERE start_date = '" + dropdownDay.SelectedIndex.ToString() + "' - '" + dropdownMonth.SelectedIndex.ToString() + "' - '" + dropdownYear.SelectedIndex.ToString() + "'";

thanks for the fast reply.
there isn't any error now, but i encounter some problems displaying my result in the gridview table.
when i run it, it doesn't displays any table/data at all, unlike my previous 'search by description' which is able to display out.
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source =" + Server.MapPath("myFile..mdb") + ";");
conn.Open();
string query = "SELECT code, description, start_date, start_time, venue FROM Event WHERE start_date = '" + dropdownDay.SelectedIndex.ToString() + "' - '" + dropdownMonth.SelectedIndex.ToString() + "' - '" + dropdownYear.SelectedIndex.ToString() + "'";
OleDbDataAdapter comm = new OleDbDataAdapter(query, conn);
DataSet ds = new DataSet();
comm.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
@__@ could you kindly guide me on this part?
thanks alot..

How can i read sqlconnection string from a text file.

Why would you want to do that? You would typically store connection strings in the ConnectionStrings section of your app.config/web.config.
If you must read it from a text file, use the ReadAllText[^] method.

May be you can change the sql used for binding...
for example,you could change "select id from user" into "select id as '<%=what you want%>' from user "...
I am not sure you get my meaning for my bad english.

How to determine programmatically if Framework 2.0 Full trust is set in trusted sites or not?
|
|
|
|
|
I'm not a CAS expert, but can you decorate a method with [PermissionSet(SecurityAction.Demand, Name = "FullTrust")], then call that method? If the method throws a security exception, you're not running in full trust.
