i have a dropdownlist control in asp.net which resides in a user control .The yuser control has a updatepannel .I want to set the dropdown selected value to a hidden field .How will i do this in javascript /Jquery .I don't want to use server code?
View 3 Replieshow 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.
View 1 RepliesIs that possible? The reason why am doing this is because I need to parse that variable into a an JQuery function so I wanted JQuery to read that field. Can I Assign that value in base class or I have to do it within default.aspx pageload method?

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'm having a time finding out I could not do something simple as :
On the onchange event getting the new selected checkbox, this with jquery.
The checkboxes are located in the following div :

This all located in a form, when I will find out the selected radio on change I will post the form and use the value of the hidden field to know the selected radio button. Nothing really difficult.
The js code :

I must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change

Question. Say for example if i have a business entity -> Customer, which has customerId, customerName and customerType. I have created an asp:Hidden Variable hdnCustomer to runat="server"
If i wanted to serialize the value of the customer business entity (in the code behind) to the hdnCustomer then how would i do that?
// Psudo code
Collection customerList = new Collection();
customerList = BusinessAccess.GetCustomerList();
hdnCustomer = serialize and assign the value of 'customerList' to hdnCustomer;
...
...
// Later on a select index change of one of the drop down lists
inside the event handler for the drop down list
{
Collection customerList = new Collection();
customerList = deserialize the value from hdnCustomer
int a = Convert.ToInt32(ddlDropDown.SelectedValue);
foreach(a in customerList)
{
// Do something
}
}

I have a dozen tables, and two dropdown lists.The first drop down list shows the table names. The second dropdown list needs to be poulated with the data from the specific table selected in the first dropdown list.I wrote a stored procedure that will query the selected table name choosen in the the first dropdown list. My results though are only showing this...

Values in multiselect dropdown not getting selected when Select All option is selected for a SSRS dropdown. There are multiple dropdowns on the page. We have one dropdown whose output is being used to populate the second dropdown using a stored procedure. When we check the Select All checkbox on the dropdown then ideally upon page refresh all the values should get selected in the dropdown, but in this case the page refreshes back to the blank dropdown, forcing the user to select the values again. The next dropdown too does not get populated. This makes it impossible to run the report for all the cases by using Select All. We ran the report on differnet database environments. My current location is Mumbai,India, the report worked fine when we ran it on a Bangalore,india database. This issue occurs when we try running it on a Chicago database server. I am using SSRS 2005, SQL2005.

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 have a problem
<script language="javascript" type="text/javascript">
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.
