Custom Validator - Get The "controlToValidate" Property On ClientValidationFunction?
Sep 3, 2010
<asp:TextBox ID="TextBox1" runat="server" />
<asp:CustomValidator ID="CustomValidator1" runat="server"
ClientValidationFunction="ValidationFunction1"
ControlToValidate="TextBox1"
Display="Dynamic" />
And a validationFunction:
function ValidationFunction1(sender, args)
{
}
And i would like to know if, inside the function I could get the Control to validate something like: var v = sender.ControlToValidate;

I'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?
C# (ControltoValidate):

I have quite a few text area's on my page and am wanting to limit the number of characters for each one. However each one should be able to have its own maxlength (i.e. one could be 20 characters and the other could be 100 characters). My validation on the page is all done using custom validation as the built in validation of .NET is not extensible enough for me to display my validation errors how I want to display them. So this is what im wanting to do:
Make a custom validatorPass a MaxLength value from the custom validator into the javascript function, this value must also be accessible from the code behindI can then run client side and server side validation on each textbox control. The problem I am having is passing a MaxLength value to client side script and to server side. Is there a property on custom validators which I can use to pass values around? For instance in Javascript I would want the value of the MaxLength and also the id of the Div which will show the characters remaining, and server side I would need to know the MaxLength. I have done lots of research on this and cannot seem to find an answer.

I'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;

I have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.

I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

I have a custom control, inherited from Button. This is the class definition for the control and 2 properties:
[Code]....
I show you 2 properties, only to illustrate the problem.
as you see Aplicacion property is of a custom type Sistema, and Roles property is of type List<UserRol>.
The Aplicacion property is rendered well, this way:
[Code]....
The problem I have is with List<UserRol>. I couldn't get it to be rendered. I expeect to be rendered this way:
[Code]....
Finally, this is the TypeConverter and Editor definitions for the list:
[Code]....
The UserRol class is a typical class, without any special attributes.
I have discovered that when I use the custom editor for Roles property, the collection is not persisted. When I use the default editor for the collection, the collection is persisted.

I need to create one custom text box control which should be bind with data base.
I am referring following link...
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.databoundcontrol.aspx
I used DataBoundControl to create my control but i am not able to do it properly.
public class SimpleTextBoxControl : DataBoundControl
{
private TextBox nameTextBox;
public string DataTextField
{
get
{
object o = ViewState["DataTextField"];
return ((o == null) ? string.Empty : (string)o);
}
set
{
ViewState["DataTextField"] = value;
}
}
[
Bindable(true),
Category("Data"),
DefaultValue(""),
Description("The text to display on the link."),
Localizable(true),
PersistenceMode(PersistenceMode.InnerDefaultProperty)
]
public virtual string DataTexValue
{
get
{
string s = (string)ViewState["Text"];
return (s == null) ? String.Empty : s;
}
set
{
ViewState["Text"] = value;
}
}
protected override void PerformDataBinding(IEnumerable retrievedData)
{
if (retrievedData == null)
return;
base.PerformDataBinding(retrievedData);
Controls.Clear();
nameTextBox = new TextBox { ID = "nameTextBox" };
foreach (object dataItem in retrievedData)
{
if (DataTextField.Length > 0)
{
nameTextBox.Text = DataBinder.GetPropertyValue(dataItem, DataTextField, null);
}
DataTexValue = nameTextBox.Text;
}
this.Controls.Add(nameTextBox);

I try to use CustomValidator ClientValidationFunction. The issue I have is CallBack using Asynchronous call which make it difficult to detect when the call is complete.
var callbackresult;
function ValidateSomething(src, args)

MyCallBackMethod(param); How shall I check when the call back is complete??? Any workaround?
if(callbackresult == 'true')
args.IsValid = true;
else

}
function CallBackRef(result, context)

Does anybody know of a way to set the width of a custom validtor so that the error message text will wrap if it exceeds the specified width? I have a user control that contains a custom validator which the containing page can set the error message on based on specific validation results. he user control sits within a table cell in a page. If the message is very long it simply prints the entire message on a single line ignoring any column widths that are set. I have tried setting the width property on the custom validator itself to no avail.

I am trying to understand a little more about implementing a custom model validator. I have implemented a custom model validator (derived from DataAnnotationsModelValidator<T>) for my custom validation attribute in order to do validation on the client side as well. There is not much documented about DataAnnotationsModelValidator. Besides, implementing client-side validation when is it a good idea or needed to implement a custom model validator for a custom attribute?
A separate question - in trying to understand how and when a custom model validator is used by the framework I noticed that my custom validator is always created with the context (2nd parameter in DataAnnotationsModelValidator<T>'s constructor) being a ViewContext, although it is declared as ControllerContext. Will a validator ever be created with something else than a ViewContext, and if so, when?
