View 1 RepliesRead Only Check Boxes?
Dec 10, 2010I have a report and some of the Boolean fields (both in form- and gridviews) should be displayed as check boxes (what else). Then my client calls me and says "Hey I can change the checkboxes before I print the report, what is up with that?" What is up with that, indeed? . So I check this out and everywhere I go I read the same thing, you can "disable" your checkbox, graying it out (which nobody, including me, wants) or you can create workarounds to stop the behavior and I found plenty of workarounds. The posts I have read were, I'll admit, pretty old so my question is this: "Am I missing something or do I still have to write a workaround for something so fundamentally basic that it should not even be a consideration, let alone an issue. I mean if you stick a check box in a read-only element (form- or gridview itemTemplate) it should not be editable by default, right?
View 16 RepliesCheck For A Null Object Reference When Validating Forms In MVC?
May 28, 2010I'm experimenting with validating forms in the asp.net MVC framework. I'm focusing on server side validation for the time being. I've come across an error that I'm not sure how to rectify. System.NullReferenceException: Object reference not set to an instance of an object. The code that throws the error is:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create([Bind(Exclude="ID")] MembersCreate mc )
{
mc.Modules = ModuleListDataContext.GetModuleList();
ViewData.Model = mc;
//Validation using ModelState
//
//
//line below errors when form field is empty
//
if ((string)mc.Member.Username.Trim() == "")
ModelState.AddModelError("Member.Username", "Username is required.");
if (!ModelState.IsValid)
return View();
try
{
// TODO: Add insert logic here
return RedirectToAction("Index","Home");
}
catch
{
return View();
}
}
When I put spaces in the field it performs exactly as i want, but if I leave the field blank and press submit I get the error. What's the best way to avoid this error and still validate blank form fields?

MVC :: Check Boxes Not Updating Membership Or Roles Tables?
Feb 8, 2010I've got an MVC 1.0 View that is more-or-less an attempt at reproducing WSAT.
On the Security->Manage Users page there's a column of checkboxes for "Active" for each user. Also when clicking the 'Edit roles' link a set of roles shows up in the Roles column of the table.
I'm using the standard SQL based Membership and Role providers that come out of the ASP.NET box.
For some reason, when I run the app from VS2008 all is well and I can update the Active and Roles values. However, when I deploy to a remote server, either my test server or in production, the checkboxes don't update the databse. Note that the links for 'Edit user', 'Delete user' work fine. I can create a new user or delete a user with no problems in any of the deployed locations. Also the 'Edit roles' link also works fine in that it brings up the list of all possible roles and shows which roles the user is in. The problem is specifically with the Checkboxes.
Interesting to note is that the JavaScript alert() (see below) does fire when clicking on any of the Role checkboxes. However, although the box is checked, the database is not updated on the any but VS2008 Casini. The database connection string is not changed on any of the execution sites which are running SQL 2008. IIS 7 on one deployed server (an ISP) and 7.5 on the other my in-house test server.
Here's the code I'm using to create the Roles portion of the page:

C# - Force The User To Select Minimum Two Check Boxes In Each Section In Gtridview?
Jul 28, 2010I have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupNo) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).
In every sectio/Group User must and should select minimun 2 check boxes. so If user select only one check box we need to show a pop up message as " select One more check box in that particular section" If User skips the message and move to next section we have to show the same message. We have to force the user to select more than one checkbox in the same section.
Mainly our intention is the check boxes whatever user selected in each section/Group belongs to one Category.
C# - Replacing Link Button And Label With Check Boxes / How To Pass Argument To Checkbox
Nov 26, 2010This is my repeater in GUI and code behind ..I need to replace the 'Make Default' linkbutton with a Check Box now. What I want to do is that When user Checks the checbox, the Default value is set to TRUE in DB , Also when a check box is Checked, it will be grayed out..
NOW I was just trying to implement this but there's no CommandName attribute for checkbox and not even CommandArgument attribute!!
How do I change my code now ?
All I wanna do is replace that Link Button with Checkbox. Somebody his..How do i pass arguments to this check box ..I need the command arguments for my "SetDefault" method that sets the address to TRUE if Default is selected

I am not getting it..in my Link Button now I am passing 2 command arguments like this CommandArgument='<%# Eval("UserID") + "," + Eval("IsB") %>' Now how do i pass these two Comand arguments that I need for my SetDEfault method in checkebox!? ok i got it that we use OnCheckChanged event when its check box and ItemCommand event is used when its link button...I am just not getting how will I pass these two command arguments in my checkbox
[EDIT]
Do I need to pass these two command arguments via text attribute ?
<asp:CheckBox Text='<%# Eval("UserID") + "," + Eval("IsB") %>' runat="Server"/>
