Access Viewdata From JQuery Without Using Hidden Field?
Nov 20, 2010
I am saving "Instruction" in CreateInstruction view. This view has partial view "CreateInstnAttribute" which saves "Attributes" related to this Instruction. It requires the InstnID as foreign key. The Instruction is saved using JQuery to avoid postback. So how can I get the InstnID to save the InstnAttribute? I tried HiddenField to save InstnId but I am not able to receive the value there. Can we use viewdata directly in JQuery?

I have a View loading a PartialView via jQuery. The PartialView has ViewData that the jQuery needs to access, but I can't seem to get to it from the jQuery. The code below uses the HighChart jQuery plugin (and it is just test code taken from the HighChart example page):
<script type="text/javascript">
var chart1; // globally available [Code]....
This jQuery is in the main view, because I don't know how I could put it in the PartialView with the document ready function. But by putting the call to the HighChart function in the callback of the get() function it works in the partial view. But accessing the ViewData doesn't...
How can I achieve this? I need to get the data from the PartialView action method in order to populate the HighChart data...

I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

I have a table for which I'd like to filter rows based on whether or not they contain a hidden field matching a value.
I understand that the technique tends to be "show all rows", "filter the set", "show/hide that filtered set"
I have the following jquery but I'm aweful with filter and my filtered set seems to always contain no elements.
my table is the usual
<table>
<tr><td>header></td><td> </tr>
<tr>
<td>a visible cell</td><td><input type='hidden' id='big-asp.net-id' value='what-im-filtering-on' />
</td>
</tr>
</table>
My goal is to be able to match on tr who's descendent contains a hidden input containing either true or false.
this is how I've tried the selector (variations of this) and I'm not even testing for the value yet.
function OnFilterChanged(e){
//debugger;
var checkedVal = $("#filters input[type='radio']:checked").val();
var allRows = $("#match-grid-container .tabular-data tr");
if(checkedVal=="all"){......

how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.

I have a hiddenfield, which I want to save the scroll position of asp.panel scrollbar during postback, and when during postback this value is called back to set the scroll position.
Using javascript I can grab the value from the scrollbar, and assign it to the hidden field, but when I post the page back the value has gone.
Here is my code snippet:
<script type="text/javascript" language="javascript">
function SetScroll(val) {
[code].....Am I missing something? How do I keep the value during post back?

you save data into a dynamic hidden field ,which is created dynamically during the handling of some postback event.what is the best way to retrieve it from this field upon a postback, (besides searching the request for the key of this hidden field and then retrieving the corresponding value as in the code below)?
protected void Button2_Click(object sender, EventArgs e)
{
bool found = false;
for (int i=0; i<this.Request.Form.Keys.Count; i++)

I have a form in MVC3 that includes a check box to copy data if it is the same as a previous form. If the checkbox is checked, it populates the text box with the content from the hidden field. Here's a sample to illustrate what I'm doing:
[Code]....
When the box is checked, it calls FillInfo(), which uses DHTML to fill the TextBox called "ThisInfo" with the value of the hidden field "DefaultInfo."
Here's the problem: if the form fails validation (e.g. "ThisInfo" is a required field and is left blank), the hidden "DefaultInfo" box is getting cleared out -- which I DON'T want it to do. As a result, when the checkbox is clicked, it is copying empty data into the "ThisInfo" field.

I inherited some JavaScript that I was told to integrate into our ASP.NET site. I thought this would be straightforward but it's turning out to be a bit of a challenge.
The code looks something like this:
<SELECT id="Question1" name="Question" onchange="updateQuestion();">
<OPTION value="notChosen">--Please Select One--</OPTION>
<OPTION value="in">India</OPTION>
<OPTION value="de">Germany</OPTION>
<OPTION value="fr">France</OPTION>
<OPTION value="us">United States</OPTION>
<OPTION value="ch">Switzerland</OPTION>
</SELECT>
The goal is to get the value from this HTML control into ASP.NET, however this control itself is being dynamically generated by another chunk of javascript, so I can't just change this to an asp.net control. My solution was to add the onchange="updateQuestion();" method, this JS will take these SELECT tags and place the values into an ASP.NET control:
function updateSecQ() {
var sQuestion = document.getElementById('<%=sQuestion.ClientID%>');
sQuestion.Value = "";
var questions = document.getElementsByName('Question');
for (question in questions) {
if (questions[question].value != null)
sQuestion.Value += questions[question].value + ",";
}
alert(sQuestion.Value);
}
As you can see, that's looking to update an ASP.NET control:
<asp:HiddenField ID="sQuestion" runat="server" value="" />
This appears to all work, however when I goto the server side on the form submit I see that sQuestion.Value is still = "".

I have a component that determines a value on a postback event.
protected void Button_Click(object s, EventArgs e)
{
HiddenField.Value = 5;
}
There's more involved in the value of course, but HiddenField is an asp:HiddenField control with runat=server set. I have in my javascript:
var id = $("#<%= HiddenField.ClientID %>").val();
The code in the javascript is set to be run only after the postback has occured (a different client click event) for the purpose of passing the hidden field value via QueryString to another URL (since i can't do a response redirect on postbacks and the client wants it in a different page anyway).
I tried adding:
ScriptManager.RegisterHiddenField(HiddenField, "Value", string.Empty);
To a !Page.IsPostback section of code, but the ID is still not set when the javascript is run.
