View 1 RepliesC#. : Custom Validator (ValueToCompare & ControlToValidate Property Errors) / How To Fix It
Jun 22, 2010I've searched a fair bit round and tried a number of potential solutions, suggested on their respective threads on various sites, to which none have worked for me.
My objective is to make sure the date entered, and to be stored, is not 'less than' (before) the present datei.e. Booking a reservation for a restaurant.
The first is:
"The ControlToValidate property of 'cvDate' cannot be blank..."
I've tried specifying it in page_load and .aspx source, the same has happened in both, in addition to ValueToCompare. I cant understand why it cant detect it?

Texbox2 Set To Requiredfieldvalidator1.controltovalidate Instead Of ValidationTB Textbox?
Nov 25, 2010I have site with two text boxes and dynamically create validation control. This is code from .aspx file:
<form runat="server">
<asp:TextBox AutoPostBack="true" ID="TextBox1" Text="" runat="server" Width="200px"
OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server" Visible="True" Width="200px"AutoPostBack="true"></asp:TextBox>
<asp:Panel ID="Panel1" runat="server">
</asp:Panel>
<asp:TextBox ID="ValidationTB" runat="server" Visible="true"></asp:TextBox>
</form>
This is my code-behind:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (TextBox2.Visible)
{
if (!String.IsNullOrEmpty(TextBox1.Text) && String.IsNullOrEmpty(TextBox2.Text))
{
RequiredFieldValidator RequiredFieldValidator1 = new RequiredFieldValidator();
RequiredFieldValidator1.Enabled = true;
RequiredFieldValidator1.ErrorMessage = "Second field required";
RequiredFieldValidator1.Display = ValidatorDisplay.Dynamic;
RequiredFieldValidator1.ControlToValidate = "TextBox2";
Panel1.Controls.Add(RequiredFieldValidator1);
RequiredFieldValidator1.Validate();
}
if (!String.IsNullOrEmpty(TextBox2.Text) && String.IsNullOrEmpty(TextBox1.Text))
{
RequiredFieldValidator RequiredFieldValidator1 = new RequiredFieldValidator();
RequiredFieldValidator1.Enabled = true;
RequiredFieldValidator1.ErrorMessage = "First field required";
RequiredFieldValidator1.Display = ValidatorDisplay.Dynamic;
RequiredFieldValidator1.ControlToValidate = "TextBox1";
Panel1.Controls.Add(RequiredFieldValidator1);
RequiredFieldValidator1.Validate();
}
if (!String.IsNullOrEmpty(TextBox2.Text) && !String.IsNullOrEmpty(TextBox1.Text))
{
if (Convert.ToDateTime(TextBox2.Text) < Convert.ToDateTime(TextBox1.Text))
{
ValidationTB.Text = null;
RequiredFieldValidator RequiredFieldValidator1 = new RequiredFieldValidator();
RequiredFieldValidator1.Enabled = true;
RequiredFieldValidator1.ErrorMessage = "Bad range of dates";
RequiredFieldValidator1.Display = ValidatorDisplay.Dynamic;
RequiredFieldValidator1.ControlToValidate = "ValidationTB";
Panel1.Controls.Add(RequiredFieldValidator1);
RequiredFieldValidator1.Validate();
}
}
}
}
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
RegularExpressionValidator RegularExpressionValidator1 = new RegularExpressionValidator();
RegularExpressionValidator1.ValidationExpression = @"^[0-9]{4}-(((0[13578]|(10|12))-(0[1-9]|[1-2][0-9]|3[0-1]))|(02-(0[1-9]|[1-2][0-9]))|((0[469]|11)-(0[1-9]|[1-2][0-9]|30)))$";
RegularExpressionValidator1.Enabled = true;
RegularExpressionValidator1.ErrorMessage = "Bad format of date";
RegularExpressionValidator1.Display = ValidatorDisplay.Dynamic;
if (!String.IsNullOrEmpty(TextBox1.Text))
{
RegularExpressionValidator1.ControlToValidate = "TextBox1";
Panel1.Controls.Add(RegularExpressionValidator1);
RegularExpressionValidator1.Validate();
}
if (!String.IsNullOrEmpty(TextBox2.Text))
{
RegularExpressionValidator1.ControlToValidate = "TextBox2";
Panel1.Controls.Add(RegularExpressionValidator1);
RegularExpressionValidator1.Validate();
}
}
}
TextBox ValidationTB is just to make validate on empty control. This validation doesn't work, when I try:
1. To first textbox enter for example: 2009-09-09
2. To second textbox enter for example: 2009-10-09 Now, everything is OK.
3. I change my first textbox on for example 2009-12-09 I get error Bad range of dates - it's OK.
4. I correct first textbox on 2009-09-09, message disappear-OK.
5. Again enter to first textbox 2009-12-09 - I don't have error, but it should be.
What strange - in debug mode I can see, that in code:
if (Convert.ToDateTime(TextBox2.Text) < Convert.ToDateTime(TextBox1.Text))
{
ValidationTB.Text = null;
RequiredFieldValidator RequiredFieldValidator1 = new RequiredFieldValidator();
RequiredFieldValidator1.Enabled = true;
RequiredFieldValidator1.ErrorMessage = "Bad range of dates";
RequiredFieldValidator1.Display = ValidatorDisplay.Dynamic;
RequiredFieldValidator1.ControlToValidate = "ValidationTB";
Panel1.Controls.Add(RequiredFieldValidator1);
//In debug window: RequiredFieldValidator1.ControlToValidate = "TextBox2"
RequiredFieldValidator1.Validate();
}
instead of ValidationTB control, RequiredFieldValidator1.ControlToValidate is set to TextBox2 (it isn't empty, so I haven't error message). Why TextBox2 is set to RequiredFieldValidator1.ControlToValidate instead of ValidationTB textbox and how I could solve this?
Web Forms :: Cannot Find Validator.ControlToValidate On Page With Master Page
Mar 2, 2010I'm using the following code to iterate through a list of validators on the page. For each validator, I want to set the background color for the control its responsible for validating. The problem I'm having is that FindControl method is always returning null. From searching the web, it appears the problem is that the page has a master page. Whether this is the issue or not, it's obvious that the FindControl method cannot find the ControlToValidate control.
Method used to iterate all validators on a page:
protected void ShowControlsToValidate(Page page)
{
if (page == null)
return;

C# - MVC - Blank Model Not Returning Blank Data
Jun 2, 2010I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.
[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}
So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.

Web Forms :: Blank Spaces After Zip And Why Do They Causes?
May 3, 2010I've finally figured out an issue I'm have with a zip code field being entered in a text box of a details view in edit mode. I'm trying to understand why i have the issue though. I don't understand why it keeps occurring.his what happens with the zip code field. I've been able to make it reoccur numerous times. If the details view is put in edit mode and the record is updated with the original 5 digit zip code, unaltered in any way, my regular expression validator catches it and doesn't let the update happen. If I change the replace the 5 digit zip code with a new one the update goes through fine. This new value can be a different or the same 5 digits and the update will work. If I don't change the value at all though the update will not go through.

Nov 23, 2010I have a field that is a DropDownList. When in the insert mode I want that field to be blank - It currently is displaying the first record in the table it pulls from.

C# - Why Does ReSharper Need To Scan All Files When Converting A Property To An Auto Property
Mar 4, 2011Is there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?
C# - Difference Between Timeout Property Specified In Web.Config And ExpiryDate Property Of FormsAuthenticationTicket?
Jul 3, 2010In the Web.Config we have a timeout property. Ex:
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>
</authentication>
When loggin in, we can specify a ticket expiry date. Ex:
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);
Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?
