I've tried to override error message when input incorrect data type in input field on HTML form.For example I have the model like this.
public class Person { public string FirstName {get;set;} public int Age {get;set;} }
For view, I put text input for Age to get it value.When type some string in Age text box like 'test' and press submit button. I got this error message ,The value 'xxx' is not valid for AgeHowever, I want to change this message and try many way. There 's nothing effect this message value.
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
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
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 want to have an input control for calendars and next to a calendar button that users click on it it will pop up a calendar and when the user selects a date, it will populate the input form with the date.
I have found one on this link:
[URL]
the example in the link above uses drop downs for month and day. I only need one input field. either asp.not or javascripts whichever is easier
I am using ASP.net 2.0 and AJAX 2.0. I implemented successfully auto-complete extender for my text box and it is working very good. But the problem is for Drop down list position. When the page first load and at that time if we use auto complete drop down will come properly but if the scroll bar position change then drop down will overlap the text box and it will change the position. For more info I will put screen of it.
I am REALLY new to ASP.NET MVC, and it is alien to my way of thinking.In my project, I have managed to get as far as allowing the user to add, edit or delete entries from a table. What I want to do is ensure that a specific field (i.e. "Tank_Number") does not get duplicated. What is the correct way to implement this?
I would like to use custom validation in the model class, the reason being the handy error messages, but am getting more confused as I read more articles. At the moment, I am using an If statement in the Controller, but it isn't ideal.
My Required validation for a field doesn't work because even the user didn't input anything, the watermark text is sent to the server. What's the best way to handle this? I'm using jquery and asp.net mvc.
I've got an ASP.NET 4 site on which I want to allow people to put '<' in their password. However, .NET gets in the way by blocking (what it sees as) an attempt to put HTML in a form field. I know I can turn off input validation entirely, but I only want to turn it off for this one field. Does anyone know an easy way to do that?
I'm using Data Annotations and Metadata attributes in my models to do automatic validations on my forms. Any who, I've got a problem where I have an int field I need to change the error when a letter is entered. Im guetting the default error: "The value 'A' is not valid for NĂºmero.". But since this is a spanish web, i need to change the error to something in spansih. Any who, I cant find where to change the ErrorMessage="" to what I need.
This may be a simple question but here it goes. I have an insert form that captures the current date of entry. What I would like to do is not cause the user to enter or select the current date but have it display on page load and capture to the field in the table on submit.I am rather new to ASP and am using Visual Web Studio 2008.
I'm pretty new to MVC 2 using the Entity Framework. I have two tables Company {ID int identity PK,Name nvarchar} and User {ID int identity PK,UserName nvarchar,CompanyID int FK}. A Foreign Key exists between User and Company.I generated my ADO.NET Entity Data Model, a Controller and a view to insert a record. My HTML form has the fields Company and UserName and the is when I click save a Company and User is inserted into the database. Sounds straight forward right!
My question is as follows:
I created a strongly-typed view derived from my 'User' entity. I'm using the the html helper Html.TextBoxFor(model => model.Organisation.Name) but the html name attribute for this input field is 'Organisation.Name'. My problem with this is that the dot throws up all sorts of issues in JQuery, which sees this as a property. If I want to change the name I read that I can use DataAnnotations but because I used the Entity Designer this involves using Buddy Classes. Seems like a bit of overkill just to change the html name attribute on this input field.
I'm a total newbie with MVC -- learning it with MVC3 using Razor.
I just watched the video on PluralSight and was just following along with the example. I created my own Movie and MovieRepository objects. I then created a strongly typed view for adding a new movie. This is what's in the view:
[Code]....
My Movie object looks like this:
[Code]....
If I click submit without entering anything in the input field, I get validation messages i.e. The Rating field is required or if I enter non-numeric data, I get The field Rating must be a number.
I didn't wire this and wanted to understand where this is coming from.
Using ReportViewer control v9 in .aspx page - When displaying date type parameter field in my report nothing happens when calendar icon is clicked (no calendar page, no error) in ie 8. FoxFire works.Same report works fine when viewed directly on the report server in ie8.
I have in my database the News Table which consist of => Id, Title, txt . I need to be able to get a description text from the whole text which exist in txt Field , but without any codes like <...> , just a pure text !! how can I do this?
I have an old database that still contains depreciated Text fields. I need to pull from these fields and display the results. You would think this should be easy... First my select statement caused a problem:
Code: SELECT DISTINCT ..., CustomerInstructions, ... FROM Orders where CustomerInstructions is a Text field.
The error I get: "The text data type cannot be selected as DISTINCT because it is not comparable." A quick search shows I can cast the text field as a varchar(max).
Code: SELECT DISTINCT ..., CAST(CustomerInstructions AS VARCHAR(MAX)), ... FROM Orders
Now I get an error while trying to load the instructions into a text box: "Specified argument was out of the range of valid values. Parameter name: index"
Not sure what the problem is here. I have text and a text box. What's with the "out of range" crap?
I have an html input control that is a radio button. This radio button needs to disable required field validators when selected. This is my non working code so far. What have I not done?
