How To Ensure Only One Checkbox Is Ticked All The Time
Mar 23, 2010
I am doing a survey. so basically, i will send out an email with a unique link and the person clicks the link which directs them to my aspx page. that controls i use will be bound to a datatable.
first I will need to show their existing home and email address in a control.
then i will give them 4 checkbox's to tick a certain option. also, how can I ensure only one checkbox is ticked all the time?
I will need the checkboxes to be bound as well, to show the options they chose incase they load the page again after saving.

My page was created with a multiview which has 3 views.
Now on one of the view I have a checkbox called chkpeer. So, when this checkbox is checked it triggers a submit button to be set to visible and active with the code below;
Code:
Protected Sub chkpeer_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkpeer.CheckedChanged
If chkpeer.Checked = True Then
chkpeer.Enabled = True
btnSub.Visible = True
Else
btnSub.Visible = False
End If
End Sub
The asp code is
Code:
<asp:CheckBox ID="chkpeer" runat="server" CssClass="checkbox" AutoPostBack = "True" />
Now the problem is, when I check chkpeer - btnsub becomes visible set to TRUE. Then when I move to the next View without clicking the submit button then return to the view with chkpeer,
1) chkpeer is still ticked but disabled
2) btnsub visible is SET to FALSE.
I would prefer one of the following
Either have the chkpeer checked - enabled and btnSub still Visible (Ideally)
Or Chkpeer unchecked and enabled so that when I check it again it activates the btnSub ..

I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.

I have a standard createuserwizard control, which adds a new member to my membership database. All fine, except I need to ensure that the user checks the terms and conditions checkbox before the member is created in the code-behind page. I need this to be server-side, rather than client-side, so a javascript-reliant solution isn't a solution :)
The code-behind is like this:
[Code]....
The aspx code is like this:

how to add validation to the 'Terms' checkbox? I've tried a normal validator and custom validators but just can't get them to work at all.

I am developing a web application that I want to ensure is properly licensed each time they log into it. This application can either be hosted by my company or hosted at my client's site. I wanted to do this verification via a web service hosted on my company's server, but the problem is if the client's outside internet connectivity is down I still want them to be able to run the application and have it verify when it's back up and running again.How would you propose I do this?

I have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.

<ajaxtoolkit:AccordionPane ID="accordianPaneAroundTheCheckbox" runat="server">
<Content>
<asp:UpdatePanel ID="updatePanelAroundTheCheckbox" runat="server" >
<ContentTemplate>
<div>
<asp:CheckBox ID="chkFoo" AutoPostBack="true" runat="server" OnCheckedChanged="DoBar"/>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</Content>
</ajaxtoolkit:AccordionPane>
We have something like the above. Extra stuff has been left off as it is a large page.
I place a breakpoint at the begining of Page_Load and DoBar. The first time I click the checkbox, the breakpoint on Page_Load is hit, but DoBar is not. The second time I click the checkbox, both breakpoints are hit.
Why could this be happening? I'm not dynamically generating the checkbox. It's ClientID is the same every time (no dynamically generated or ID'd containers). I've tried resubscribing to the event in the Page_Load, but it didn't hit the first time, and just hit it subsequent times twice.
Update I have tried removing the UpdatePanel completely. Not only does the whole page postback, which I don't want, but the event is still not entered. What can block/swallow an event call like that? Is there some exception deep in the bowels of a master page or framework call or something somewhere that I can't see?

in a grid view i have a checkbox column ,which is making checked based on the char value from the SQL DB.
In SQL DB field type is char(1).
My requirement is , need to pass "Y" if checkbox is true ,and "N" if checkbox is false.How to pass that parameter in an update statement.
How it is possible?I used the parameter like as follows.But it is giving me an error when i click update.Groupid parameter is working perfect.The error is coming from the "HPermission" parameter.
<asp:BoundField DataField="GroupID" HeaderText="GroupID" InsertVisible="False" ReadOnly="True" SortExpression="GroupID" />
<asp:TemplateField HeaderText="Hud" >
<ItemTemplate>
<asp:CheckBox ID="chkStatus1" runat="server" AutoPostBack=false
Checked='<%# Convert.ToBoolean(Eval("HPermission").ToString().Equals("Y")) %>'
/>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />

I've been working in asp.net webforms and I've been making a UserControl that depends on a small bit of javascript which is in an external file.
I want to be able to put a reference to the javascript inside the UserControl to ensure that it gets loaded on the page, but the problem is that the UserControl can appear multiple times on a page so I only want the script to be loaded with the first instance of the UserControl.
Is there an easy way to do this in ASP.NET Webforms?

I have some classes which can't make assumptions about de used culture. These classes should always use CultureInfo.InvariantCulture. However, I can't set the thread's current culture to CultureInfo.InvariantCulture, because other classes rely on <globalization culture="auto".
Is there a way to ensure some classes always use explicit culture method calls (like: Convert.ToDecimal(value, CultureInfo.InvariantCulture)) instead of assumed culture (like: Convert.ToDecimal(value)).Maybe my question it's not 100% clear: I'd like to detect all methods which have an overload which uses CultureInfo, but also one without the CultureInfo which uses the CurrentCulture.This includes implicit casts of numbers to string:
decimal value = 1.0;
string displayThis = string.Format("Costs: {0}", value);
The goal is to make sure some classes/methods don't assume anything about CultureInfo.

I can remember reading something on this in a book but I can't remember. How do you ensure that certain graphics have been loaded to the users computer before any of the page is rendered?

So the problem is the following :
i do have own user control. which has some javascript file in script tag included like this
<script type="text/javascript" src="../somefile.js" ></script>
or some javascript code directly on the ascx page. everything works if i place this control somewhere in aspx markup. but if i add this control to the page dynamically to some UpdatePanel place holder on postback (this is logic i can not alter), control renders itself and then i get js error message, which says that functions which are placed in somefile.js are not defined/are null. Why is this happening ? Is there anyway to force js including in this case.
the code amount is huge and i was not able to provide a simplified example with the same error,.
The script is included but somehow the functions are not defined. I'm novice to js, so is it possible that just the script is included but not executed, so the functions are not declared ???
The interesting is that if on some page my custom control is declared in aspx.

What is the best way to ensure that events are rebound after an UpdatePanel callback?
function pageLoad(sender, args){
//bind events here.
}
or
use the .live(eventType, handler) method to initially bind the events
or
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function() {
//bind events here.
});

I would like to make the contents of a file uploaded to a web server unrecoverable after it has been used. My concerns are:
When the file is uploaded, is it stored in a temporary directory (e.g. Windows Temp directory) and how do I clear all traces from there? Can the contents of the file be written to virtual memory and how do I ensure it is not or remove the contents once written? If I encrypt the file, would I still have to worry about the contents being saved to the Temp directory, virtual memory or elsewhere before the file was encrypted? Can I perform a secure delete in all the concerned about locations (temp, virtual memory, any others) and how do I do this? Are there any concerns I have missed or an alternate way to achieve the stated goal?

When a user enters a value I want to check against the other values in the database before allowing the record to be inserted.
It is a nvarchar type column.
Is it best to use a unique constraint (if so, how) or what would be the way to programatically check to make sure this name does not exist. It is not a username, just a name value that will be used in routing.
