Suppose I have a form with only a button on it. Each time I click on the
button, I want an other new button control to be added on the form, of
course with some functionalities.
This is a simple example to make my question clear. I need to learn how to
make dynamic changes on my form.
How will create no.of check boxes as per user requirement in ASP. How will we keep the names to the check boxes.
<% for i=1 to n %>
<input type="checkbox" name=? >
<%next%>
How we use the naming convention in the place of? How can we check the condition by using above naming convention
if( checkbox.checked =true) then
<< body of the condition>>
end if
I have a Base class that is inherited by Form.aspx them Form.aspx loads 2 controls Menu.ascx that never changes and a body control that is selected dynamically at runtime. On each of the body controls I have a Function for validating the page Val() .
What I need to do is when an image button is clicked on the Menu.ascx I need to Fire off Val() in the Body control. Is this possible? I have tried setting a session var. but I have to load menu.ascx after the body control for the page or the body control does not function properly?
FormView & DetailsView are great controls in the new version of ASP.Net, but
I am finding it tricky to display more than the record that either control is
bound to at the time. For these controls to be useful in any mode other than
read-only, we need the ability to populate controls like drop downs that hold
associated data, which in the DB represents foreign key related data. In
order to do this, do I create a template field that has a seperate control
that binds to a different data source pulling back the "lookup" data?
I have a list of radio buttons that is populated from the database.
The value of this radio button from the DB is SalesRanking
If one selects the radio button (Sales Ranking) then I want to display 2 select boxes.
Is this possible?
I have the following problem: I have an asp-page which contains a loginview
with two templates (loggedin- and anonymoustemplate). How can I access a
textbox inside the the loggedintemplate from the code behind c# module?
I tried: (TextBox)Page.FindControl("TextBox1") but that will result in a
null pointer.
I also tried:
(TextBox)Page.FindControl("ContentPlaceHolder1.LoginView1.TextBox1") with the
same result.
I am using the object command in asp page to download and register my controls on the client machine. But when a upload the file and run the page on client machine its shows means the permission to download the controls but it didn't download it on client machine as a result i am not able to use any of the control function from page. what to do.
I am using this object tag to download
<OBJECT
ID="voxPlayer"
CLASSID="CLSID:45C0D292-1955-4ABF-8FFE-BEDC323ADBD9"
CODEBASE="http://<ServerName>/<myControl>.cab"
height = "10"
width = "20"
border = 2>
</OBJECT>

I am trying to set up the security for my website... and understand that ASP.NET comes with a Membership Administration tool which is great, does it all for you! however, it stores all the user data (i.e. username password etc) in a default database.
What i would like to do is to GET the user information from this database once a new user is created and store it in my own database - hopefully i will only need the username and password... as then i can link my own user table to my employee table using a user id field? does this make sense???
Basically, i need to know HOW to get this information from the database that ASP.NET automatically creates and add this info into my own User Table.

I have an ASP 3.0 page that contains an ActiveX control that I wrote in VC++ v6.0. Under Visual Interdev I can debug the ASP code just fine. However, when I get to an ASP line that references my ActiveX control the debugger does not go inside my C++ code allowing me to debug the ActiveX control.
If I load the ActiveX control project from VC++ with Internet Explorer as the debug executable I have the same problem. Break points in the ActiveX control's code are not respected. I know I'm compiling in Debug mode,how to get these breakpoints to be respected?

View Replies View Relatedif its possible to create a custom validation control which can enable or disable any given control depending on whether a checkbox is checked or not?Currently my solution involves posting back to the form which in turn enables or disables appropriately.
I have noticed with some of the standard validation controls that the screen does not refresh (postback) for the error message to display.Is it possible to enable/disable a control instead of displaying an error message, and do this without posting back to the form to refresh?I have seen some custom controls which can do this for sale, but they cost $$$.
