Is there an easy way to clear all the selected items of a checkbox list control? When a user has selected multiple items?
View 2 RepliesI have two checkboxes on my form.
- How can I uncheck a checkbox using client side code when the other checkbox is checked?
- Is there a way to check server side on form submission that at least one check box is checked?
In Edit mode, when I check unchecked items, the Update works correctly, but when I clear the checked items, the items are still true in the database. My textboxes and dropdown lists all work as expected. The related code is below. Why won't the cleared checkboxes write to the db? When I set a breakpoint in the ContactRecordOnUpdating method, the values for the unchecked checkboxes are true (which is undoubtedly why they are written to the db that way).

HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />.
Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ?
Update:
Context is a simple Contact/"Send us a message" page with 8 asp:TextBoxes on the page (where the user enters the name, address, phone, email, message, etc.). Then he clicks on submit, the Onclick message handler in code-behind sends an email to some administrator, and all the form fields the user filled in should be emptied and he gets a notification in a label ("Message sent blabla..."). I want to have the form fields cleared to avoid that the user clicks again on submit and the same message is sent a second time.
I have a asp.net web application and I'm using cache (HttpRuntime.Cache) to save some stuff from db.
I also update db from time to time so that data in db does not match the data in my application's cache.
Is there any way how to clear my application's cache without modifying any source code or republishing the page?

How do I enable a check_change for a checkbox in VB.

Front end code:

Here is my situation. I have inherited an MVC 2 application. I am learning MVC 2 on the fly with this application. I am trying to validate a checkbox by doing this: Grey out the submit button until the user clicks on the "checkbox" then the submit button is enabled. 1st question: Where do I place the code to make this happen? 2nd Question: How do I go about doing what I explained? I wanted to use a simple javascript code within the click event of the checkbox but I don't see this in MVC 2.

I have this table with checkbox for each row:
[URL]
table code inside the ASPX page:
[URL]
So I'm trying to implement the delete selected button.. How exactly do i point to the specific checkbox for a particular row from codebehind when all 3 have the same name chkSelected? I know how to do it with a gridview, but not quite sure how if we do it with a for loop..
Can I do something like this inside btnDelete_Click?

I am displaying my table data using listview control. It is working fine.
Now I would like to add a checkbox in front of every item so then when user checks the checkbox and click on delete button inside or outside the listview control then i want all the records to be deleted.
How bind the data through checkbox if checkbox checked is true
View 3 RepliesI am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then
Launch = 1
End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?
This code works fine if i use this inside ssercontrol > panel and i have a checkboxes in table when no checkbox is checked its works fine .... but if i disabled and checked any of the textbox then this doesn't work .... in usercontrol why ? i didnt understand ..
<script type="text/javascript" language="javascript">
function checkboxChecked(){
var allInputs = document.getElementsByTagName("input");
for(var i=0; i<allInputs.length; i++) {
var chk = allInputs[i];
if(chk.type == "checkbox" && !chk.disabled && chk.checked) {
return true;
}
}
alert("OOps! You haven't selected all available checkboxes");
return false;
}
</script>
