How can i use a checkbox to represent a boolean bit field in an MVC View? Out of the box, it defaults to a textbox..There is no boolean datatype in SQL Server 2008 so i used a bit datatype. I guess its a custom template but i cant seem to get the syntax right.
View 2 RepliesI don't know how to bind nullable boolean field to RadioButton in ASP.net.
Following code works well for non-nullable field

how I can bind nullable boolean field to RadioButton?
I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
created a create view for an entity in my Linq model which had a bit field in it but it turned out a textfield..can you give me an example of an ascx that will enable me use a checkbox for this instead of a textbox, which the create view template uses for ALL the fields.Also, how can i get the template to use html.displayfor() instead of html.textbox?
View 5 RepliesI know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:

View 4 RepliesBasically I have RegisterModel2 that has a Person class. My requirement is that Phone Number and Address are not required for registration. But if they try to enter a Phone number of Address then it should validate it. Problem is that it is always stating that the child fields of Phone (area code, number) and child fields of Address (street1,city,etc) are required. Is there a way to annotate in the RegisterModel that a parent class is not Required but if any data in a child element is given then and only
then should the child elements be validated?
My Person EDM class has a nullable 0.1 -> 0.1 navigation property to Phone and Address.Here is the person class

I found a very piculiar care in ASP.Net MVC webpage submission to server. The model object is bound to the action event. It was working fine. I added another interger field to my model object and added a control to the webpage(.aspx). When I submit the page without entering data in the new field, I found that my ModelState.IsValid in the Action Event, is false and there is error registered as the field value is required. I am surprised why it will be a mandatory field? when I have not set is as Mandatory ? Is there some thing wrong I am doing? I putting the samples below.
New Filed in ASPX:
[Code]....
Controller Object :
[
{
AcceptVerbs(HttpVerbs.Post)]public
ActionResult AddDriver(Driver driver)
}
On submit of the page when control comes to the AddDriver Action event , I found the ModelState.IsValid is false.
why it is happening as I have not put any require attribute in the Model object's field.
Page validation using Required field validator is not firing I configured everything and tested in other page and found its working fine.
I placed my controls under TabContainer is that the reason for not firing.
I'm trying to write a form for a user to leave a testimonial on the website. I would like a group of inputs related to the users name (title, firstname and surname) or an input for their company name to be required. They can leave both if they like, but they must at least either fill in all the inputs related to their name or the input for their company name.can I do this with the RequiredFieldValidator?
View 3 RepliesI've currently got a RequiredFieldValidator added to the top 3 fields of each generated set of questions. The questions are dynamic, and what I'd love to do is pop up a red "YOU MISSED SOME FIELDS...blah blah" msg above the Submit button when the user misses those top fields. (I did do this previously with a custom validator, but I've had trouble doing this w/the dynamic fields that I've created.)Right now, if you miss a top-3 field, the page just does nothing, and the user has to manually scroll up to the top of the page to see "required field" pop up in red next to the missed field.

I want to put validation on a combobox to ensure user selects/enters a value. I've tried using a the standard required field validator which doesn't work. So I would like to do the validation using javascript/jquery.
Not sure how to approach. When I look at how the combo box is rendered, it appears as a unordered html list. There is also a hidden field but this always seems to be set to 0.So is it possible to do this validation client side. I've read so many posts about this but I havn't got an answer yet.
