detection of card reader - ASP.NET Discussion Boards

Yes you can't see the design view whenever you are rendering the control at run time. It will show you error because at design time what is present in the control if you re rendering it at run time do design time IDE don't have any information about UI controls to display

Thank you.
No its not even at run time, once i finish clicking the Web Control Library Template, i just get c# code and cant get to design view window.
Do you have links that can led to steps on how to do this, i might be missing something.

I think you are creating Custom control
For custom control there is no Design view
You are resposible for rendering,State,... implementing all these functionality
Please have a small search in google

Hi,
I am using sql server 2005 and ASP .Net 2.0, VS 2005.

When I increased a parameter in Stored Procedure and in application, and again running the application it throws an error that, Parameters does not match with the stored procedure parameters.

All i have to do is restart the machine and again run the application. Then it does not throw the error and it works fine with the extra parameter in application as well as in storedproc.

I am unable to understand what is the exact problem, that i have to restart the machine and then it accepts the changes

Sandeep Kumbhar

What machine are you restarting?
The user's
the web server
sql server
After the restart has the SP changed at all?

For each checkbox in checkboxlist

What do you mean? You want to limit the amount of checkboxes?

You need to close your RadioList with:

You also need to set the onclick for the button in the aspx code

Thank for reply but i already closed tag radiobuttonlist.But i don't know why it's not show in web. Any one can help (sorry for my bad english)

Did you do the 2nd bit of my post? Add the onclick delcaration to the aspx control. Its currently not specified.

you have:
<asp:button id="Button1" runat="server" text="Button" xmlns:asp="#unknown">

you need
<asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click" xmlns:asp="#unknown">

Dear All,
I am using C# , asp.net , ajax1.0
My requirement is I have to give alert message and redirect to another page based on some condition

Please suggest some link or idea

Please help

You could use a javascript popup box and then have a yes or no condition in it. Depending on which the user chooses you can redirect them to a certain page.
