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
[code]...

I have an ASP.NET TextBox ID="txtDate" in my usercontrol. It has ValidationGroup="MyUC" set. Now my UC is inside a Repeater Control. So there will be multiple instances of the same textbox. I am able to get all textboxes like: $("[id$='_txtDate']");
Each of the txtDate will have a separate ValidationGroup assigned to it, dynamically. So I want to get a textbox based on the id + ValidationGroup using jQuery / javascript.
Edited based on Josiah's Reply and the way I found:
my scenario is kind of complicated to include entire code. In short the textboxes are attached to jquery datepicker and the code below runs when a date is selected. The same handler is attached to multiple textboxes. Here is what I have:
var valgrp="MyGroup"; /*this mygroup is dynamic but keeping static for e.g.*/
var txtdate1 = $("[id$='txtDate']").filter(function(){if(this.Validators!=null){return this.Validators[0].validationGroup == valgrp;}});
var txtdate2 = $("[id$='txtDate']").filter(function(){return this.validationGroup == valgrp;});
alert("date1- " + txtdate1.val()); /*this returns date selected from datepicker*/
alert("date2 " + txtdate2.val()); /*this returns empty*/
Depending on the date I want to do something else. So txtdate1 is currently working for me where I don't have to add class to my textbox. I was playing with the txtdate2 which isn't behaving how I was expecting and so I had to post this question.
Here is a sample test to see this.validationGroup not returned:
$(function () {
$("#btntest").click(function () {
$("[id$='txtDate']").each(function () {
alert(this.validationGroup);//returns undefined
alert(this.Validators[0].validationGroup); //returns "test"
});
});
});
<input id="btntest" type="button" value="button" />
<asp:TextBox ID="txtDate" runat="server" ValidationGroup="test"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" Text="*" ErrorMessage="Required." ControlToValidate="txtDate" ValidationGroup="test"></asp:RequiredFieldValidator>

I have a button on which I wish to validate a specific ValidationGroup in ASP.NET. This button is not a server control, but a standard a tag with an onclick event on.
I have multiple validation groups on this page, so by calling Page_ClientValidate() is not enough, as the other validators will kick in as well.

I know how to enable/disable individual validator controls on the client side using
ValidatorEnable(validator, false);
But how do you enable/disable all the validators within a ValidationGroup?

I am successfully including a javascript resource by calling ScriptManager.RegisterClientScriptResource at the end of OnPreRender in my custom control. However, the resulting script tag is being included before the automatically included script tags that define things like Type and Sys which my script depends on. I thought they were defined in the order that they are included but I can't include my script any later then I am. How can I control the order in which the script tags are included?

what wrong with these validators.
[Code]....
Button1 works fine, it causes the validator to work. Button2 works fine, it doesn't cause the validator to work because it's CauseValidation=false But, Button3 in Repeater1 items doesn't work as I want, it still fire the validation of the validator.

I have an AJAX TabContainer. Each tab I have a ValidationSummary control with different ValidationGroup name for each tab. The problem is, now nothing show sup in the ValidationGroup when q required field is blank. The web form won't get submit but there is nothing displaying on the page either. All the RequiredFieldValidator are not showing in the web form either. All the RequiredFieldValidator controls are set to use the correct ValidationGroup too.

I have a user control that has multiple instances on a single page.
Is it possible to have each instance use a unique ValidationGroup? I could expose a property, but I'm wondering if there's any way to do it automatically.

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...

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?

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 ?

My code:
<asp:RangeValidator id="RangeAmountDeposit" runat="server" ErrorMessage="Znesek za vplačilo je premajhen!" ValidateEmptyText="True" ControlToValidate="AmountDeposit" ValidationGroup="ErrormessageValidationGroup" MinimumValue="1" MaximumValue="10" Type="Integer"
Display="dynamic "/>
ValidateEmptyText="True" - not works.
I want to display text only ValidationGroup = "ErrormessageValidationGroup" and add a picture next to AmountDeposit (view image): <asp:Image ID="Image12" ImageUrl="~/Images/warning.png" ImageAlign="TextTop" runat="server" />

I'm sure you've seen sites that display a portion of the available text in a limited space followed by an ellipsis or a [more] link. That's what I need to do. The text is in a database field, and includes carriage returns and line feeds. I can't just count the number of characters. How can I only display the text that will fit in a defined space? I've tried using a panel control with the height defined. I've also tried a div with the height defined. Neither has worked. How is this done?

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>
