Web Forms :: Accept Textbox Value Even If It's Null?

Jun 14, 2010

I have a javascript to validate and avoid null values for my form but there are some textboxes that I need to be 'optional'. I tried erasing the validation for province address and province contact in javascript to make it optional, but the problem is whenever I add the values in the database, an error message appears "Input string was not in a correct format". It's in C# This is my present code wherein the provincial address and provincial contact must only be optional:

protected void submitButton_Click(object sender, EventArgs e)

MVC :: Validation Doesn't Accept Dropdownlist Null Value?

Jan 8, 2010

I'm currently stuck with a problem with MVC2 RC and validation on a dropdownlist :

I have a page with some fields and a dropdownlist. The dropdownlist is not a mandatory field so I would like to save a null value into my property.

Unfortunately, I can't validate my page with a null selected value, because when I look into the modelstate just on the first line of my action, I've already an error telling me I must choose an item.

Is it normal working of dropdownlist validation or is it a bug ?

Localization :: Textbox Needs To Accept Text From Other Languages?

Nov 8, 2010

how non English language input works with asp.net textboxes.

1. Can a regular asp.net textarea or a textbox accept text from languages other than English?

2. If yes, then how does the user enter non English language text

3. Is there a way to detect what language the user has entered text and make UI changes accordingly. (Ex: Make a button visible if non English text is entered)

4. Can non English text be stored in a varchar column in a SQL Server database? If not, how do I store this text?

VS 2010 Textbox On Webform Doesn´t Accept Input?

Mar 25, 2011

I´m creating a user page to enable editing their profiles. When hitting the "update" button, it turns out that the field still contains the old value, although you´re looking at the new one, ie the text property of the textbox isn´t the value of the parameter which in fact gets its value from the text property.As far as I know I haven´t done anything I haven´t done before, both in apps and website?

Fuga.
Code:
Update Persons set [First Name] = @First
Code:
.Parameters.AddWithValue("@First", Microsoft.VisualBasic.Trim(Me.TextBox1.Text))

Forms Data Controls :: Handling A Null Value In Textbox FormView (on Button Click To Calculate Totals)

Mar 17, 2011

I have a rather large formview that asks for a variety of input values (physical totals vs pos report totals). I have created vb code to calculate the differences and subtotals of various types prior to inserting the data so people can check for entry errors.

Its a closing reconciliation form. Here's the problem: If they forget to enter 0 in a field that doesn't have any totals, a big ugly error message displays. I would like to avoid this. I can tell them until I am blue in the face to remember to enter 0 and not leave any blank fields, but realistically its going to happen and I need to handle it in the programming.

I have been struggling to either default the values to zero to start with, replace a null textbox with 0 before the calculate runs...but I can't get anything to really work. What is the best way to handle this?

Here is the aspx page:

[Code]....

And the code behind page with working "Calculate" as long as fields are not left blank (I took out all the test code that made it not work at all)

[Code]....

Finally, the error message I am getting is the following:

[Code]....

I can't seem to find the right combination of programming to account for the "" string to be 0 so that it will add or subtract values in my calculate. I have my sql table setup with default values of 0 so if a field is left blank it will be entered into the database as 0 and not null. It is really just for my inserting of a reconciliation and the running of Calculate Totals to double check their work prior to inserting into the database.
