View 1 RepliesSince I'm new to coding and I'm trying to understand why here is a little more detail on the question.If you have a text box and you are limiting the input to say 2 charactrs do you really need to validate the input further? What I have is a text box that has a max length of 2. Is there a security reason to add a validator to the textbox. I should add this is in Asp.net.
View 8 RepliesI have a textbox that I want the user to enter an integer in.1) I have created a required field validator, to ensure it is not left blank.2) A compare validator, to ensure the value entered is an integer using datatypecheck.3) A range validator to limit the range of the entered integer.If a letter is entered, instead of an integer, errors from both 2) and 3) are displayed.Is there a way to only show the error from 2) if a letter is entered and 3) if the integer is out of range - rather than both?
View 1 RepliesIf I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?
Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?

VS2008 c#, asp.net 3.5, ms sql 2008How do I validate user input in TextBox inside a FormView [Insert Mode] with MS SQL 2008 Database?* FormView #fvInsertProjectInfo* TextBox #txtProjectNameCurrently, user could insert a new project using the FormView, but will only be found out that the project is already existed when pressing the INSERT button. To make it more user friendly, I would like to check that the database does not contain a record of the project the user trying to insert (by comparing value in txtProjectName with the Projects table in the database)

In my edit View, I have the following:

Lastly, my validation in my controller looks like this:
[Code]....
The validation works for both First and Last in that the Validation Message is properly displayed for the appropriate error. However, the input-validation-error class is not being set on the textbox.
How do I ensure that the input-validation-error class gets set on the textbox when the textbox is tied to a field in a nested class of the Model?
A very easy one hopefully - what expression can I use to validate an integer to ensure it is greater or equal to zero, but less than 2,147,483,647 (i.e. the maximum value of an integer)?
For example 0 =< x < 2,147,483,648
I'm trying to validate an integer range with a CustomValidator. The range is set dynamically, so when either the min/max values on my usercontrol change, the client validation function is updated. However, I can't get the validation function to fire. I have this code:
<asp:CustomValidator ID="vldAnswerValid" runat="server" ControlToValidate="txtAnswer" Display="Dynamic" SetFocusOnError="true" ValidationGroup="answer" OnServerValidate="vldAnswerValid_ServerValidate" Enabled='<%# !IsReadOnly %>' />
Setting the function from the codebehind with: vldAnswerValid.ClientValidationFunction = " function(oSrc, args){ alert(1); args.IsValid = false; } ";
But there's no message displayed and no alert. Am I missing something?
We have an application we are maintaining, cant make changes to the database, but new form was created and need to pass the values into the table now..
there are 2 columns in the table that are to store the date, but the datatype is set to float.
When i try to pass the values into the procedure in my code behind i get errors that says
"input string was not in a correct format"
my procedure is expecting float, my class method is expecting float, my parameter.add is passing it as float cmd.Parameters.Add("@sdate", System.Data.SqlDbType.Float).Value = sdate;
So im guessing that on my page code behind where im calling the insert method and passing in my textboxes, i need to make some adjustments.. just not sure what they are..
float stDate = System.Convert.ToSingle(txtSdate.Text);

View 1 RepliesI have an input...
<input
id="ratingField"
runat="server"
type="hidden"
/>
this hidden input is used by a star rating control. the user gives a star rating of 1 to 10 by clicking on the stars and some javascript detects which star was clicked and fills the input with the corresponding number.
I want to use a RequiredFieldValidator to ensure that the client has selected a star and if not return an error message to my validation summary.but the validator seems to be throwing an exception. How do I do this?
I'm working on an ASP.NET/C# app.
I have 2 text boxes and I need to validate if the input text for both of them are not both null
ex:
if(string.IsNullOrEmpty(TextBox1.Text) && string.IsNullOrEmpty(TextBox2.Text) ) //FAIL!!! else
that is, at least one txtBox has values
I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator?
I am always thinking about validation in any kind on the webpage (PHP or ASP, it doesn't matter), but never find a good and accurate answer. For example, a I have some GET-Parameter, which defines a SQL query like DESC oder ASC. (SQL-Injection?) Or I have a comment-function for user, where the data is also saved in a database.
Is it enought to check for HTML-tags inside the data? Should the validation done before adding it to the database or showing it on the page? I am searching for the ToDo's which should be always performed with any data given from "outside".
