Web Forms :: Using ValidatorValidate With ValidationSummary

Dec 2, 2010

I'm trying to get a textbox to validate onblur. I have the following code:

myPage.aspx:
<asp:TextBox ID="txt1" runat="server" /> <asp:Button ID="btn1" runat="server" Text="Submit" OnClick="SubmitForm"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="No text" ControlToValidate="txt1" Display="None">
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
myPage.aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
txt1.Attributes.Add("onblur", string.Format("CheckForValue('{0}');", RequiredFieldValidator1.ClientID));
}
protected void SubmitForm(object sender, EventArgs e)
{
if (Page.IsValid)
{
// process ...
}
}
myPage.js:
function CheckForValue(sender) {
var control = document.getElementById(sender);
ValidatorValidate(control);
}

The validation control will validate if I set the Display to Dynamic or Static, but it won't display the error text in the ValidationSummary when the onBlur event is fired (its fine if the form is submitted using the button). Does anyone know if this is a restriction of using the ValidatorValidate function or am I doing something wrong?

Web Forms :: Gridview And ValidationSummary?

Jul 20, 2010

I have a Gridview control on my webpage which is loaded using a GridViewTemplate dynamically. I have added FormatValidators toemailaddress, date type data fields. I also have a ValidationSummary control to show the error summary at the bottom of the page.Now, on the webpage, when a user enters incorrect data into two emailaddress fields, the ValidationSummary control summarizes the error messages and shows same error message twiceone per row. I think this is a standard behavior of the ValidationSummary control.

My question is, is there anyway to show the error message only once per column i.e. even if two email address fields are incorrect, the error message shown by validationsummary will appear only once instead of twice? I am referring to showing the validationsummary once per column of gridview instead of once per row...

Web Forms :: Two ValidationSummary On One Page?

Apr 20, 2010

I'll try to make it short. I have two validation summarys on one page (one for the LOGIN and one for the REGISTER).

But when i click on the LOGIN button, it shows not only the missing fields from the LOGIN part but also the ones from the REGISTER part.

I was woundering if I could use two validations summaries without that problem ?

And if no, is there any alternative ? Like how do all the websites in Asp.NET do to have two forms or more per page ?

Web Forms :: ValidationSummary Control Messages?

Oct 20, 2010

When my validation fires on my web form, the validation summary writes out the same error message for each control that was in error
twice! I have no validation groups in my web form.Here is my html for the Validationsummary control.

<code>

<asp:ValidationSummary ID="ValidationSummary1" runat="server" DisplayMode="BulletList"
ShowMessageBox="true" ShowSummary="false" EnableClientScript="true" HeaderText="You must enter a value in the following fields:" />

</code>

A typical control is set up below as follows:

<code>

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="HospAcctno"
ErrorMessage="Patient Info: Hosp Acct#" Text="*" runat="server" />

</code>

Web Forms :: Controlling The ValidationGroup And ValidationSummary With JavaScript And C#?

Jan 13, 2011

I'm new to programming and recently spent some time navigating these forums and searching google to learn how to manipulate Validations with ClientValidationFunction using JavaScript and OnServerValidate with C#. Now that I have a decent handle on it I wanted to give back a bit. I hope some of you all can use this information. Mess around with it and see what its doing and how.I'm using Visual Studio 2008 as my IDE. I did not include a master page so just copy and paste, set break points, and add a watch to the following:

x
options[x].value
options[x].checked

Web Forms :: Inserting Personal Error Message In ValidationSummary?

Aug 21, 2010

I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator.

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary.

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Why ValidationSummary Cause A Postback

Dec 14, 2010

I am new to ASP.NET so may be my question sounds stupid but here is it anyway: Why a postback happens when we use aValidationSummary control? When I am using RequiredFieldValidator control then postback is not happening if the validation fails which is right. But if I useValidationSummary control then postback starts happening even if the validation should fail.

I have 2 text boxes txtUserName and txtPassword and a button btnLogin on my page. I have a RequiredFieldValidator control for each text box. If any of the text box is empty and I click the Login button, the postback does not happen and I got error message(s) which is good.

[Code]....

Now I add a ValidationSummary control. Now if any of the text box is empty and I click the Ok button, the postback happens which is bad.

[Code]....

C# - Add The FailureText As An Item In A ValidationSummary?

Apr 8, 2010

I'm currently working with the ASP.NET login control. I can set a custom failure text and I can add a literal on the page where the failure text is displayed if the login fails. I also have a validation summary on the page in which I collect all errors that can occur (for the moment it just validates that the user has entered a login name and a password.

It would be really nice if I could add the failure text of the login control as an item in the validation summary, but I'm not sure if this is even possible?

Hoping that the massive brainpower of stackoverflow can give me some pointers?
