View 1 RepliesIn an Asp.net MVC app, I have inherited this problem (if it is a problem?) where one developer has used String for Date type.
In my model the property reads:
[Required]
[DisplayName("Registration Date")]
public string Registrationdate { get; set; }
The business requirement is that the field is not required, but if there is something in that fields then it must be a valid date.
How would you implement this requirement, without changing the data type?

View 4 RepliesI have an ASP.NET gridview where I allow the user to edit a record. I need to validate multiple fields as one. I need to require that the user either enter a first and last name OR a company name. All three cannot be blank. Most of the sample code I am finding does not address the text boxes only being visible while the gridview is in edit mode. When not in edit mode, the text boxes do not exist so
document.getElementById('<%= editFirstName.ClientID %>') throws an error upon page load.
[Code]....
validate the text boxes which are created dynamically?
Meaning only one of them can have a value, but not both.
I suspect one validation control can't handle both.
I've problem with validating all text boxes in PlaceHolder. I made PlaceHolder and I've no idea how to check that all textboxes have integer numbers as a text.
public void Made_Matrix (PlaceHolder Matrix, int Size){
for(int row=0; row < size; row++){
for(int col=0; col < size; col++){
TextBox TB = New TextBox();
Matrix.Controls.Add(TB);
TB.ID = TB + Convert.ToString(row) + Convert.ToString(col);
TB.AutoPostBack = "true";
}
Matrix.Controls.Add(new LiteralControl ("<br/>"));
}
}
public void TB_Validate (PlaceHolder Matrix, int Size){
for (int row = 0; row < size; row++){
for (int col = 0; col < size; col++){
string Ident = TB + Convert.ToString(row) + Convert.ToString(col);
how can i find text hidden in TextBox with ID from Ident? And how to check if it's numeric? I suppose that in .NET there's no function like IsNumeric(), am I right?

I need to validate a date in a web forms application. For this I use a CompareValidator with
Operator="DataTypeCheck" Type="Date"
The problem is that this Validator doesn't work properly on Firefox with 2 digit years. ( javascript error: m[2] is undefined)With a 4 digits year it's working properly.
This problem is described also here:[URL]two-digit-year-in-mozilla-based-browsers-throws-js-exception
i have two controls in one page, grid control and a form control, inside the grid control there is a textbox control. my question is when ever click update in the gridcontrol, the validation control in the form control get fired and the page does not post to the server.
View 2 RepliesI have a about 6 or 7 text boxes which needs to be validated to make sure they are not empty from server side code. So how I usually do this is, check each textbox 1 by 1 to ensure that they are not empty. Are there any other efficient methods to do this? I have searched on SO and have found out that adding all the textboxes to a list and using a for each is a much better method. Are there any other ways that this can be achieved? Thanx a lot in advance :)

how to get the validator to make sure that the YEAR is acceptable. For instance, I can enter a year of "0000" and the validator will not catch it or display the error message. I can even enter a year of "9999" also. The only time the validator catches it is if I input something like "45/95/7589" for the date.

View 3 RepliesI got one web page which is developed by using Asp.net. and in that page I have got one tab control which developed by using Ajax control toolkit (tab container). In that tab container i have got three tab pannels. In the first tab pannel have got two drop down list boxes and one image control box. wat I was trying to do is that by using calendar extender control in ajax control toolkit i was trying to display a day in the first drop down list box and month and year in second drop down list box. when user click on image control during run time a small calender will pops up and then user will select the propective date according to there choice and when they have finish selecting the date from the calender a day will display on first drop down list box and month and year will display on second drop down list box.
I was keep trying to do that but i was failed. then i took one test box from the toolbox and i was got success in displaying the user selected date in the text box by using ajax calender extender. How to display that date instead of one textbox into two separate drop down list boxes from which a user can select manual date from drop down list as well and from the calendar as well also when the page loads, the two drop down list boxes must show current date ( by default)
In my website their is a textbox for adding birth date...
I am using the ajax calendar for selecting date...
I want that the user who enters the date shld be above 16yrs old...
Means i want that the date should be minus from the current date and should be calculated as 16yrs or above it...
For example:- user 'A' selects a date 5th may 2005 and the current date is 28th march 2013 (which means that the age is 8 yrs)... than it should show an error that "your age should be above 16 yrs"...
Front-end:- Asp.net C#
Back-end:- sql server 2005
Note:- I am using Ajax Calendar....
i have a maskedtextbox in that i need to enter date following format
