I'm having 1 or 2 problems with a checkbox.
I have a form that can be either submitted or saved. Within this form there's a number of checkboxes.
I've succesfully achieved this on a textbox (postback) but don't know the syntax for checkboxes
My questions are: how would I open the form with these checkbox's previously checked? In addition to how do I insert the value from a dataSource:

I am working on a datagrid that has a column with checkboxes... the checkboxes should be checked when the page loaded. The problem is that whenever I trigger a postback, all the checkboxes will be unchecked!!
I don't know what is causing this or what should I do to prevent it from unchecking the checkboxes.
i'm using a gridview and has a column of checkbox that is within a template field.
I want to do it in C# but I only found this code in VB
[Code]....
why when I create a checkbox using HTML.CheckboxFor the values remain after postback where as if I just create a simple HTML checkbox in HTML after postback the value is no longer there?
What is the difference between HTML.Checkbox vs. an HTML checkbox? Why does one retain the values after postback and one does not?
I have a web flow (asp.net) which has a drop down and a check box.
When the check box is ticked, I need to disable some fields in that form.
When a specific value is selected from the check box, I need to disable other fields.
I specify the checkbox like this:
<%=Html.CheckBox("IsResponseUnavailable", Model.IsResponseUnavailable)%>
And the drop down like this:
<%= Html.MyDropDownList(string.Format("Questions[{0}].Answer", i), (IEnumerable<SelectListItem>)ViewData["Periods"], Model.Questions[i].Answer)%>
Where MyDropDownList is an extension of Html.DropDownList
I've heard about auto-postback - but unsure how to use it
I have the following in an aspx page:
<td colspan="2">
<% DisplayParties(); %>
</td>
In the code behind for the aspx page, i have this (e.g. I build HTML for the checkboxes):

Not my proudest moment, but whatever. The problem is that when this page posts back via some event on the page, I never get these tags in the Request.Form collection.
Is this simply how ASP.NET works (e.g. only server-side control post back) or am I missing something simple.

View 2 RepliesOn my page: a Button1, a ListView1, a Panel1 and inside Panel1 an ImageButton1In the ListView1_PreRender-Event the property Panel1.Visible = false or Panel1.Visible = true is set.1. After first loading of the Page Panel.Visible = false ist set in ListView1_PreRender.2. After the postback click on Button1 the criteria for the visibility of Panel1 are evaluated, thus setting in the ListView_PreRender Panel.Visible = true.
View 3 RepliesI have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"

I want to create a search form that will check MS Access db. The form will have many checkboxes for users to check if they want to query specific amenities for a lodging query. It would probably be easier if somebody could recommend an example of how to do this rather than explaining each part. How to set setup up Access Datasource to return only those checkbox fields that are checked. So for example if there are checkboxes for the following.
Fireplace, HotTub,PetsAllowed,LaudryFacilities,Telephone,TV,DVD....
How to set up if user only chooses the first 3 selections? Perhaps my biggest obstacle is the select statement as all the fields in question here will be of boolean type Yes/No aka True/False.
I really hope I'm missing something, but I cannot for the life of me figure out a simple way to do the following: I have a database with a list of Ids, Names, and a bit field representing a boolean. Example:
Id | Name | Active
21 BoB 1
43 Ron 0
23 Tom 1
All I want is to list the names on my webpage, with check boxes beside them, and when I click the checkbox the database automatically changes the status... that's it. A checkedlistbox control would be amazing, but it doesn't seem to exist in web form. The problem with checkboxes is asp:checkbox doesn't have a "value" field anymore. So when I'm handling CheckedChanged event, I have no way of knowing what the Id of the changed entry is. I have seen a couple things online that require searching through control hierarchies to find some Id somewhere in your dataset, but that does not make sense.There MUST be a way to do something like this:
[Code]....
At this point I think it's easier to use 2 list boxes, 1 that lists people where Active=0 and one that lists people where Active=1 and then an OnSelect event that moves them between each other. That's how easy checkboxes SHOULD be.
I needed to redesign the input page. I have in place individual checkboxes to represent fferent selections. For the database, the result for these checkboxes are in a seperate table. The insert only works for the first table which are textboxes. The information is not getting stored for the checkboxes. I have it separately eventually the checkboxes will be used for a search feature. For example, the information of the company, phone, address are getting inserted into the database but the checkboxes refering to the business is not being stored. What am I doing wrong with my code? Am I missing "true" for the checkboxes? The following is my code:

View 11 RepliesI have a page that im using javascript to do a select all / unselect all for my checkboxes on the page. Now i need to determine in the code behind if all of them are checked, im wondering if it would be easier to just set a session or something whenthe select all is checked, but that wouldnt be accurate, because after you select all, you still can uncheck some..
So i need it to check at the time the button is clicked.. there are currectly 30 checkboxes, NOT a checkboxlist.
I tried using the site search but getting an error has occured when i click to search..
I got a checkboxlist in which I bind the items with data from the DB.Means the rows in my table re directly bind tochkboxlist to display as the 7 listitems in it.Together with that am binding the state also(ie,whther it is previously checked or not by the user).Now the user have the option to edit this settings by checking or unchecking the listitems in it.We need to update this in the DB accordingly.
I need to pass the Id's of the checkd items separated by a "|" along with the state 1 or 0.Meaning if the user check 1st threecheckboxes in the list my parameters shud be (userId,1|2|3,1|1|1)..I tried in the below way..
public
void UpdateNotificationSettings()
{
NotificationDO notifyDO =
new NotificationDO();

In a datalist i've got a checkbox with a autopostback.
But there is an error if i run it:
System.InvalidCastException: Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.CheckBox'.
There are 40 checkboxes, if the person selects 1 i need to deselect all others. Very easy, but how to use correct coding for it?
protected void chkWerkblad_OnCheckedChanged(object source, EventArgs e)
{
CheckBox s = source as CheckBox;
if (s.Checked)
{
foreach (CheckBox c in s.NamingContainer.Controls)
{
if(c !=null)
c.Checked = true;
}
}

The checkboxes need to be checked or unchecked depending on the data retrieved.
I want to add two checkboxes to selected days in a calendar control. I can do that but I can not figure out how to get the checkboxes to fire an event. I tried to get a button to fire and event by iterating through the panel without success either. Here is my code so far:
