I have ArrayList in my Model and want to iterate through it in my javascript. I am using following code but its giving me error : CS0103: The name 'i' does not exist in the current context
for(var i=0; i <= <%=Model.KeyList.Count%>; i++)
{
alert('<%=Model.KeyList[i]%>');
}
How to get rid of this?
I am using a Session Arraylist to hold information about an online user. However, I am having troubel accessing the data. The error seems to be in the last bit because I can access one value of sample data just not print out a number of values. I have an class penalyPoint that has the following constructor:
public PenaltyPoint(string penaltyCode1, string penaltyDate1, string PenaltyPointsAwarded1, string penaltyBan1)
Then in a button response I have the following response which holds the data in a session arraylist variable as the user can enter a number of these objects. I will put a capacity limit on the arraylist later on.
//Assign the data in the form to a PenaltyPoint Object
PenaltyPoint penPoint = new PenaltyPoint(ddlPen1Code.SelectedValue, txtPenDate.Text, txtPen1Points.Text, txtPen1Ban.Text);
//The current driver number has to be set before this page is called
//Temp
int currentDriver = 0;
//int currentDriver = (int)(Session["currentDriverNum"]);
//create an arraylist to be used for transferring arraylist to session
ArrayList penPointsDrive0Array = new ArrayList();
if (currentDriver == 0)
{
//if the session is equal to null then nothing has to be returned from session
if (Session["penPointsArrayListDrive0"] == null)
{
penPointsDrive0Array.Add(penPoint);
Session["penPointsArrayListDrive0"] = penPointsDrive0Array;
Response.Redirect("PenaltyPoints.aspx");
}
else
{
penPointsDrive0Array = (ArrayList)Session["penPointsArrayListDrive0"];
penPointsDrive0Array.Add(penPoint);
Session["penPointsArrayListDrive0"] = penPointsDrive0Array;
Response.Redirect("PenaltyPoints.aspx");
}
}
Then I try to access the data in the arraylist but I getting nothing printing out. I am just trying to test the data at the minute. I am not that use to arraylist so this might be the problem.
public partial class TestPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
ArrayList answer = new ArrayList();
ArrayList driver1 = (ArrayList)Session["penPointsArrayListDrive0"];
PenaltyPoint ps = new PenaltyPoint();
string output;
for (int i = 0; i < driver1.Count; i++)
{
ps = (PenaltyPoint)driver1[i];
string answertemp = ps.getPenaltyCode();
output = answertemp;
}
}
}
I can't get the final part to collect all the values into a string it keeps on coming up with errors.

I'm working on an ASP.NET app.I'm using a UserControl for a year calendar.This UserControl has 12 asp.net calendar controls (for the 12 months of a year)
I'm trying to build a jscript function that can access to one (or more) of the 12 month calendar, but I can't access them.
example:
"<asp:Calendar ID="CalendarJanuary" runat="server"></asp:Calendar>"
here's my function
function SetCalendar(controlId) {
document.getElementById(controlId+'_CalendarJanuary').VisibleDate = somedate
}
but this is allways throwing an error:'Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object'
it seems is not finding the calendar and I'm sure i'm passing the right controlID
I have a form in my content page for which I am doing some client side validations via Javascript. The Javascript behaves as expected if I place the JS code directly in the content page. But if I place the JS code in it's own file and try accessing that from the content/master page (through the script tag's src attribute), I get a run time error when the validation function in JS being called.
To be specific, I get the below error:
Microsoft JScript runtime error: Objected expected/required at this line document.getElementById('<%=txtemailId.ClientID %>').value
txtemailId is in the content page.
Javascript code is placed in validation.js and accessed via master page.
The reason I guess is that when .net is parsing the files, it is unable to substitute txtemailId.ClientID with the client side value that would be generated later on. So, how should one go about it?

I have implemented a CollapsiblePanelExtender with a button that collapses/expands a panel. I also have a javascript function that can collapse the expanded panel when a certain condition exists somewhere else on the page.
The problem I am having is when I programatically collapse the panel, the extender is not aware, so the Collapsed property remains false and the CollapsedImage and CollapsedText are not updated. The next time I click the button, the extender is updated to a collapsed state, but nothing happens on the page because the panel was already collapsed. It is just resynchronizing the Collapsed, CollapsedImage, and CollapsedText properties to match the panel's already collapsed state.
Is there a way I can update the Collapsed, CollapsedImage, and CollapsedText properties in javascript to match the actual state of the panel?
I have a javascript variable in the script tag. I am assigning a value to that variable and I want the same value to be assigned to the label control e.g. consider the sample code below :

How do I assign the value of variable a to the label?
I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.

t.click();
}
