C# - Validating Textbox Using Javascript In MasterPage
Sep 17, 2010
I am using javascript for customValidator to validate textboxes in ASP.Net. The code works perfectly when I am using a normal page, but as soon as I put that inside a MasterPage, the code doesn't work. Below is the code for my aspx page. If I put this code inside a MasterPage it doesn't work.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<script type="text/javascript">
function validateOrFields(source, args){
var sUser = document.getElementById('TextBox1');
if (sUser.value == "")
{
args.IsValid = false;
}
else
{
args.IsValid = true;
}
return;
}
<div>
<asp:TextBox ID="TextBox1"
runat="server"></asp:TextBox>
<asp:CustomValidator ID="FieldValidator"
runat="server"
Text="Enter either a user name"
ClientValidationFunction="validateOrFields" onservervalidate="FieldValidator_ServerValidate"/>
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
</form>
</body>
</html>

I have radiobuttons within a datalist. The page where they appear is within a master page. The method I had in mind of achieving the validation is with a custom validator and the following sub:
[Code]....
The problem with this code is form1 is not declared. As it is passed in from the master page.
I also have tried another method as follows:
[Code]....
With this sub:
[Code]....
I then get the error Microsoft JScript runtime error: Object expected
Here is the datalist. I need to make sure the user selects an answer for each question:

I have a textbox that is set to readonly so users won't try to type something in it. It is then populated when a treenode is clicked. I want to validate what is in the box after it's populated from the treenode click but if i have it set to readonly, in the codebehind it shows up as an empty string. if i take the readonly off it shows up populated. what would you do about this?

I am retrieving list of projects and project IDs using autocompleteextender.I want a kind of functionality that doesn't allow user to input any characters (or)will change the text box color if the input doesn't retrieve any value from database.Though, I have found a solution by calling function through OnClientPopulated. But this function calls back the webservice "GetCompletionList" method.I don't want to recall one method two times..

I'm using asp.net validation controls which work fine. I've since introduced an HTML checkbox which should be ticked before the form can be submitted. My function for this reads as follows:
function terms(form) {
var terms = document.getElementById("chkTerms").checked;
var errorsArray = new Array();
if (terms == false) {
//alert("Terms not checked (works)");
errorsArray.push("You must agree to the terms and conditions.");
if (errorsArray.length) {
document.getElementById("termsOutput").innerHTML = errorsArray.join("
") + "<br />";
return false;
}
}
else {
document.getElementById("termsOutput").innerHTML = "";
}}
It is called as follows:
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="return terms(form)" />
The problem I have is seems I can either use the asp.net validation OR the custom checkbox validation I wrote. After the form posts however, the asp.net validation fires!

I thought the following code was correct but it doesnt seem to wrk, its causing an error on my page and when I remove it the page is fine, it doesn't actually give exact details of the error on the page just says "syntax error" in the browser that is all.

I have a textbox in one grid-view column where upon entering a particular value and losing focus of the textbox, should post to the server to get the text validated through a server-side method. If the entry is valid, a result set to fill rest of row cells would be returned, else the bgcolor of the textbox needs to be changed to Red.
I tried posting back through the obvious way, i.e. making the textbox's autopostback as true and wiring up a server-side OnTextChanged event handler to validate the entered value.
It is working with this setup, but is also affecting the remaining page controls behaviour. For example, if I click a button in some other grid after entering some text in the textbox, the OnTextChanged handler gets called thus preventing the button's click event, which I also wish to call to execute its functionality.

I'm trying to get the value of a textbox using the PreviousPage method and the previous page utilizes a MasterPage for the page's layout. I've read through many forums laying out the ground work on how to do this, but for whatever reason I am just being unsucessfull in getting this to work in my project.
Mark-up of previous page using a master page template:
[Code]....
VB Code-behind page for second page:
[Code]....
What really confuses me is that when I step through the code it goes all the way through the if statement but never gets the text value from the previous page.

does anyone have any working code that uses javascript to open and close a cpe when the CPE is in a masterpage? It seems like the javascript never is able to find the CPE when it is on a master page. I have an DropDownList on the page and when certain items are selected, i want to collapse or expand when others are selected. It seems to work fine on a regular page, but not when it is a page nested in a master page. It is adding a suffix to the CPE and javascript is unable to find it.

I need my MasterPage to be able to get ControlIDs of Controls on ContentPages, but I cannot use <%= xxx.CLIENTID%> as it would return an error as the control(s) might not be loaded by the contentplaceholder.
Some controls have a so called BehaviourID, which is exactly what I would need as they can be directly accessed with the ID: [Asp.net does always create unique IDs, thus modifies the ID I entered] Unfortunately I need to access
e.g. ASP.NET Control with BehaviouraID="test"
document.getElementById("test")
if I were to use e.g. Label control with ID="asd"
document.getElementById('<%= asd.ClientID%>')
But if the Labelcontrol isn't present on the contentpage, I of course get an error on my masterpage.

This is my master page code
[Code]....
Now what I want to do is, using JavaScript, hide the "phMenu" contents in the childpage. For this, I have written a function called " showHideMasterPageContent " in the masterpage which I am calling in the child page.
My trouble is that, I get a null reference since obviously, when I looked at the source, I see that only the contents of phMenu are rendered and not the phMenu control itself. Now how to refer to phMenu in JS ?

I am having a slight issue with grabbing data from my masterpage into my content page (as a whole).
I have generated a public property for the my textbox and the contentpage can see this public property. But it comes across empty (even from within the masterpage). Now I guess the problem is with the property itself (possibly). It also shows as empty when I response.write it's value to the page.
Even when I call the value of the property in the masterpage it comes across as empty. The way I have this setup is that a textbox named pageTitleField has it's value updated from an iframe. All is working well and the textbox has its value updated correct upon iframe content changes. This is great. Now I just need to pass this textbox value into my content page and then set it as the document title.
see my code thus far.
My MasterPage

My MasterPage CodeFile
[Code]....
My ContentPage

I know the public property is being seen from the content page because if I just do a Response.Write(Master.GrabPageTitle) I see System.Web.UI.WebControls.TextBox appearing as the output of that property. So it appears hat the textbox value is not being captured in the public readonly property.
