C# - Custom Validation Through Web-method?
Sep 8, 2010
For validating login field (at register form) I use customValidator
<asp:CustomValidator id="uniqueLoginValidator" class="validator" runat="server" ControlToValidate="tbUserName" ErrorMessage="Login duplicate" ClientValidationFunction="LoginValidate"/>
For validate login I need consume wcf, so decide use web-methods
<script type="text/javascript">
function LoginValidate(oSrc, args) {
var login = $(".loginField").val();[code]....
For successfull validating I should setup args at ClientValidationFunction, but I get result validation only at callBack. So how can I setup args for validation work.

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.

I am creating a custom control by inheriting a server control, say LinkButton. There are properties like "BorderColor" available in LinkButton. Let's say, I don't want this particular property to be available when I create an instance of the custom control.
I want to completely hide this particular property (I don't want to override it but disable it.)
My code is as follows:

I have created my own custom role provider class "SGI_RoleProvider" and configured properly.
Everything is working fine.
Suppose that I have added a public method say "SayHello()", then how can i call that. Because if i am using Roles then the method is not displayed. If i am forcefully using that Roles.SayHello() then compiler gives the error.
how can i call this. Because creating a new instance of SGI_RoleProvider is meaningless.

Is there a method in jQuery that I can customize an invalid validation myself instead of using jQuery plug-in validation?
For example, if the form is valid do this below.
$('form').validate();
if ($('form').valid()) {
//do something
};
But if I wanted to have a cutomize invalid method I could do this below.
$('form').validate();
if (!x == y) {
$('form').valid() = False; //[:(]
alert('Form is not valid.');
};

I was trying to write a method to be called from a CustomValidator to determine whether a string property was unique or not. I was trying to make it generic so that I can reuse the code for many different string properties. I'm using reflection. Does this seem like a way too complicated way of doing this? Does there happen to be a better way of doing this but still making it generic?
public virtual bool IsPropertyUnique(T entity, string newValue, string propertyName)
{
var values =
Context.GetTable<T>.Where(e => string.Equals(e.GetType().GetProperty(propertyName).GetValue(e, null), newValue)).ToList();
return values.Count == 0;
}

I am new to this MVC and have a basic question related to validation. I have a create view for customer and based on the customer entity partial class metadata, I am validating the user input and its working fine as expected when the user clicks the create button.I also have a search button in the same create view, which is used for auto generation of some of the field values. When the user clicks the search button the action method create (post) is called with the corresponding button value as argument.the issue here is when the user clicks the search button most of the user input fields will be blank and the validation fails because of that.

I have a validation method,
public string ValidateField() {
string strtemp = "";
strtemp += ValidateField("Visitor_Name", visitor_name.Text, 10, 50, "string", true);
strtemp += ValidateField("Phone_Number", phone_number.Text, 5, 20, "string", true);
strtemp += ValidateField("Contact_Number", contact_number.Text, 4, 25, "string", true);
strtemp += ValidateField("Visited_Date", DropDownList1.SelectedValue, 1, 30, "int", true);
//strtemp += ValidateField("V_Id", v_id.SelectedValue, 2, 35, "int", false);
[Code] ....
And inside the button click event the validation working like
if (ValidateField() == "") {
output = usbll.insertBAL(userval);
Response.Write("Record inserted successfully");
}
It is working correctly...But It is not showing error message.So how to show the error message that is returned from the above condition ValidateField()...If the condition not satisfied i want to show a error message like length should be greater than or equal to minimum length and so on ..

I have just started using MVC2 in VS2010, and I noticed that on the Register page DataType.EmailAddress doesn't actually do any validation, so it does not check whether or not the Email Address entered is valid. Should I write some email validation code in the HttpPost Register method of my AccountController, or is there another way to do this?

I have a custom control that is based off the gridview control located at: here The control is basically a gridview that automatically creates a column of checkboxes that can be used to "check" individual rows in the gridview. During the gridview's "CreateColumns" event, the "checkboxcolumn" is created dynamically. The checkboxcolumn also contains another checkbox in the header that is used to "select/deselect all" checkboxes in the column. Since the gridview does not automatically remember the state of the checkboxes in the checkboxcolumn on postback, I added a method to the control called "SaveCheckBoxState" which stores the indexes of the checked rows in Viewstate, and then I modified the "OnRowDataBound" event to check the Viewstate and reset the checkboxes based on the Viewstate.
I then added a call to "SaveCheckBoxState" in the gridview's OnSorting and OnPageIndexChanging events. This works great so long as I'm sorting or changing pages. However, I need it to update the viewstate everytime someone clicks or unclicks one of the checkboxes. At this time, the checkboxes are rendered with an onclick event that calls some javascript to highlight the row, or in the case of the checkbox in the header, to select/deselect all checkboxes. I need to call the "SaveCheckBoxState" method from the javascript used by the customcontrol, or I need to find a way to modify viewstate from javascript and perform the same action as "SaveCheckBoxState".
I've tried adding the "SaveCheckBoxState" to the onclick event declaration in the checkboxes, but when run, it simply tells me that the method is undefined. It doesn't exist in the parent page, and I don't think I should have to make an event for the parent page to pass the click to. It seems to me this should be all self contained within the custom control. Does anyone know how I can acheive this? Here is the code for the gridview OnPreRender event where the onclick event of the checkbox is set:
protected override void OnPreRender(EventArgs e)
{
// Do as usual
base.OnPreRender(e);
// Adjust each data row
foreach (GridViewRow r in Rows)
{
// Get the appropriate style object for the row
TableItemStyle style = GetRowStyleFromState(r.RowState);
// Retrieve the reference to the checkbox
CheckBox cb = (CheckBox)r.FindControl(InputCheckBoxField.CheckBoxID);
// Build the ID of the checkbox in the header
string headerCheckBoxID = String.Format(CheckBoxColumHeaderID, ClientID);
// Add script code to enable selection
cb.Attributes["onclick"] = String.Format("ApplyStyle(this, '{0}', '{1}', '{2}')",
SelectedRowStyle.CssClass,
style.CssClass,
headerCheckBoxID);
// Update the style of the checkbox if checked
if (cb.Checked)
{
r.BackColor = SelectedRowStyle.BackColor;
r.ForeColor = SelectedRowStyle.ForeColor;
r.Font.Bold = SelectedRowStyle.Font.Bold;
}
else
{
r.BackColor = style.BackColor;
r.ForeColor = style.ForeColor;
r.Font.Bold = style.Font.Bold;
}
}
}

I am creating a custom 'control' which is simply made of two html inputs [type=text] but can't figure out how the validation will work on the view end.
I want to treat these 2 inner controls as asingle control so when a error is added to modelstate both of these inputs are highlighted in the view and a single validation message is shown.

I am new to asp.net and I have a problem. When the users insert in a editor for a decimal field something other than numbers, they get an error "Field name" is not a number. But I don't want them to receive this message I want them to receive another message. I have no problem with this with required and range validators. Is there any way for me to do this?
I am not refering necessarily to changing the culture just displaying another message.
