hide form after Submit

just wanted to know how to hide the form (eg: registration form) once its submitted.
i want that once the user enters the details in the form and submits just a message saying "Details added to be displayed" rather the form getting post back

Thanx in advance

enclose the form elements in a panel, in the click event set the visibility of the panel to false.

example:

code behind:
Sub next_Click(sender As Object, e As EventArgs)
pnlform.visible = false
End Sub

html code:
<form runat="server">
<asp:panel id="pnlform" runat="server">
UserName: <asp:TextBox id="UserName" runat="server" /><br />
Password: <asp:TextBox id="Password" runat="server" TextMode="Password" /><br />
<asp:Button id="next1" onclick="next_Click" runat="server" Text="Next" />
</asp:panel>
</form>

Thanx Miranda :thumbsup:

</FORM>

</asp:Panel>

Code Behind is :

private void Button1_Click(object sender, System.EventArgs e)
{
if(!Page.IsValid)
return;
mypanel.visible=false;
string fname=txtfname.Text;
string lname=txtlname.Text;
string uid=txtuser.Text;
string pass=txtpass.Text;
string dept=drpdep.SelectedItem.Value.ToString();
DateTime dt= DateTime.Today;
string ddt=dt.ToString();

string sqlin="insert into issueusers values('"+fname+"','"+lname+"','"+uid+"','"+pass+"',"+dept+",'"+ddt+"',0)";
SqlCommand cmd=new SqlCommand(sqlin,myutility.connection.getinstance());
cmd.ExecuteNonQuery();
Response.Write("<center>User Added</center>");

}

Here i am using Singleton application for the connection. How do i use transaction in this code for insert

It dint work

private void Button1_Click(object sender, System.EventArgs e)
{
if(!Page.IsValid)
return;
mypanel.visible=false;
string fname=txtfname.Text;
string lname=txtlname.Text;
string uid=txtuser.Text;
string pass=txtpass.Text;
string dept=drpdep.SelectedItem.Value.ToString();
DateTime dt= DateTime.Today;
string ddt=dt.ToString();

string sqlin="insert into issueusers values('"+fname+"','"+lname+"','"+uid+"','"+pass+"',"+dept+",'"+ddt+"',0)";
SqlCommand cmd=new SqlCommand(sqlin,myutility.connection.getinstance());
cmd.ExecuteNonQuery();
Response.Write("<center>User Added</center>");

}

I see 2 things
1st this line of code only runs if the page does not validate, correct?
if(!Page.IsValid) instead of if(Page.IsValid)

2nd your SQL Insert statement is missing the names of the fields to insert the values into
string sqlin= "insert into issueusers values('"+fname+"','"+lname+"','"+uid+"','"+pass+"',"+dept+",'"+ddt+"',0)";
instead of
"insert into issueusers(fname,lname,uid,pass,dept,ddt,SomeOtherColumn) values('"+fname+"','"+lname+"','"+uid+"','"+pass+"',"+dept+",'"+ddt+"',0)";

Also, use a "placeholder" instead of a "panel". Placeholders are more ideal as containers to be made visible or not. Panels generate table tags, which depending on how you use them, can mess up page layouts in some browsers. Placeholders are much cleaner.

Panels generate a DIV tag not a table... The PlaceHolder Web server control does not have any visible output and is used as a place holder to add controls at run time.
