Is there any simple method to pass viewdata to masterpage. For example, I create a viewdata["test"] in the testing controller. I pass it to masterpage so the masterpage can show this value.Is there any simple method to do it? Can I use session to do it and how?

I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.
So I create jSON object on client-side
var myJsonObject = {
"arg1": var1,
"arg2": var2
}
and pass it in to
WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);
When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]
So in following server-side function, the argument value is [object Object]
public void RaiseCallbackEvent(string jsonObj)
I was expecting a string representation of JSON object. How do I pass in a string representation?
Is there a way to assign/pass/copy a javascript variable to a server side variable in C#? For the sake of argument, let's say that I was able to parse some JSON for variables that I want to store and assign them on the client (ie. var = FirstName and var = 25 and var = someDateTime, etc) .
View 4 RepliesI am trying to attach a server-side event to lookup the city/state for the user-entered zipcode in a field like the one below.

Since there is no lost focus event to capture, has anyone had any luck getting this to work?
If I have a standard HTML textbox

but got a readonly error.
I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.
View 5 RepliesI've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

View 2 RepliesI have created dynamic control with both server and client side events.. if i set client side event server side event is not firing..

View 2 RepliesI'm dynamically binding tables and sub tables using nested listviews. On the client side I have a piece of jQuery that is toggling the visiblity of TRs witin the tables in order to provide a group expand / contract view option.
On postback I'm obviously loosing my class changes that I have applied via jQuery. I'm wondering what the best approach to maintaining these client side class changes is? I've considered creating a hidden input control per table to store the indexes of the visible TRs at the time of expanding them. The intention being to then look for the indexes during postback / rebinding and add the visible classes to each corresponding element.
Is there a better approach or some native method of passing back the client side style / class change to the server during postbacks?
I have a requirement in which I have to call a JavaScript function in between my server side event and in that JavaScript function code I have to set hidden field value and in next line of that same event i have to use that hidden field value.
View 4 RepliesFor the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
How can I get the width of a textbox in pixels from server side, if the width in html is set as 95%? MyTextBox.Width.Value gives me 95, i.e. percentage.
View 4 RepliesI'm adding <ASP:TextBox>'s to a page in code.I'm going to set their ID and stuff like that.I'm wanting to retrieve the text of those textboxes on a button press.Now I know I can't simply do "Me.MyTBName1.Text". I guess I could loop through the controls and compare IDs. I'd rather be able to get the textbox's text directly somehow though.I could use Javascript to get the value, but I don't think I can use it server-side at that point.
View 1 RepliesI have a textbox in my application which has multiple validation on it e.g. RequiredFieldValidator, RegexValidation and CustomValidation. My page has several similar textboxes. So I just copy-paste and change id and controltovalidate properties and it is working.
Since similar tbxs are going to be used on another page as well, I think it would be nice to create my own custom TextBox control with built-in validation.
Here are two approaches I have found and tried:
1: Implement from IValidator perform my custom validation in Validate Method. As shown here: Self-Validating TextBox But it does not show how to implement client-side validation.
2: Create custom control that derives from TextBox and add asp.net built-in validators I need. As shown here:Custom TextBox. I tried the code and it works server/client side.
I like the first approach but don't know how to implement client-side validation. I know I need a client-side js function. I can do that. I know how to include my js file using Page.ClientScript class but don't know how to integrate all together and make it work.
I can create a UserControl or the second approach above but for now I am specifically looking to learn and implement client-side validation from custom control.
I want to filter a grid at server side based on the value typed in a text box. And the filter should happen as the user types in text box. Since there is no server side event like keypress on a textbox, I decided to do use the client side onkeypress event and call a server side code using PageMethod. But then ran out with the limitation of PageMethod being static and I can't access grid from server side code.

I have two textboxes, one isfor 'program' and the other for 'description'. I have a predefined set of programs and it is associated descriptions in the database.
Example : For program named 'Test' it has the description as 'Valid' in the DB Table
For example, when enter a program name in the program textbox as 'Test', its associated description 'Valid' should be populated automatically to the 'Description' TextBox on losing focus from the 'Program' TextBox.
How can I achieve this using asp.net mvc
