I have...a dynamic populated select box several input boxes a submit button form fields are loaded initially using cookies several dynamic populated divs
I want... start loading the content of my DIVs after all FORM elements have been loaded completely (= filled with data, select boxes are populated)
Sample code:
[code]....
I have an UpdatePanel with a repeater in it that is re-bound after a user adds an item to it via a modal popup. When they click the button to add a new row to the repeater the code-behind looks something like this:
protected void lbtnAddOption_Click(object sender, EventArgs e)
{
SelectedOption = new Option()
{
Account = txtAddOptionAccountNumber.Text,
Margin = chkAddOptionMargin.Checked,
Symbol = txtAddOptionSymbol.Text,
Usymbol = txtAddOptionUsymbol.Text,
};
Presenter.OnAddOption(); // Insert the new item
RefreshOptions(); // Pull down and re-bind all the items
mpeAddOptionDialog.Hide(); // Hide the modal
// ... Make call to jQuery scrollTo() method here?
}
This works fine and the new row will show up quickly via the UpdatePanel. However, there are often hundreds of rows and where the new one is added is based on the current sorting column used. So, I wanted to take this as a chance to use the sweet jQuery ScrollTo plugin. I know that if I give it the ID of my overflowed container div and the ID of an element within it, it will smoothly scroll straight to the users newly added row. However, there are two problems:
I need to find the appropriate row so I can snag the ClientID for it. I need to execute the jQuery snippet from my code-behind that will cause my newly updated repeater to scroll to the right row. I've solved #1. I have a reliable method that will produce the newly added row's ClientID. However, problem #2 is proving to be tricky. I know I can just call ScriptManager.RegisterStartupScript() form my code-behind and it will execute the JavaScript on my page.
The problem I'm having is that it seems that it is executing that piece of JavaScript before (I'm guessing) the newly refreshed DOM elements have fully loaded. So, even though I am passing in the appropriate jQuery line to scroll to the element I want, it is erroring out for me because it can't find that element yet. Here is the line I'm using at the end of the method I posted above:
string clientID = getClientIdOfNewRow();
ScriptManager.RegisterStartupScript(this, typeof(Page), "ScrollScript", String.Format("$("#optionContainer").scrollTo("{0}", 800);", clientID), true);
What do I need to do so I can ensure that this line of JavaScript isn't called until the page with the UpdatePanel is truly ready?
I am dynamically creating a table of checkboxes on my test.aspx page. The dimensions (row and column count) of the table are determined by querying the database. In test.aspx page, I do the following:
<script language="C#" runat="server">
protected void Page_Load ( object src, EventArgs e ) {
//Query the database to get the data for rows and columns
CheckBox[] chkBox = new CheckBox[rows * columns]; //creates a collection of checkboxes
//Iterate over the query set in a double for loop to create dynamic checkboxes
}
</script>
Right now I have the number of rows=20 and columns=10, but it can increase (with the columns more likely). I used the Net tab in Firebug to ascertain the time taken by different events and found that GetTest.aspx is taking close to 4 minutes, which is too long a time to wait. Is there a way to being down the page load time? Is my approach to create dynamic check boxes correct?
In my Page_Load() event, I'm calling a Sub (in a module UserMenu.vb) that reads an XML file which has the user menu entries. The final menu should be an <ul> with several <li>, some of them with anidated <ul> within. As I understand, I may use a asp:Panel in my page to position a container for this elements I read and in this sub I try to add them using new BulletedList and new ListElement BList.Items.Add(LItem)), but when I get to Panel.Controls.Add(BList) it throws an error that says BList should be inserted in a Form. Why? Aren't they just <ul> and <li>? What other alternative I have to create <ul> and <li> in a specific part of my page?

how to load pages into DIVs as we can do in iframes? Currently in my legacy application in which I have frames depending on requirement I load different ASP pages into the iframe, can we do something similar in DIVs also? I know I can write inner.HTML in DIVs.
View 3 RepliesSo I am new to ASP.NET MVC and I would like to create a view with a text box for each item in a collection. How do I do this, and how do I capture the information when it POSTs back? I have used forms and form elements to build static forms for a model, but never dynamically generated form elements based on a variable size collection.
I want to do something like this in mvc 3:

How do I do a text box for each guest? And how do I capture them in the action method that it posts back to?
Currently, I have a list of PhoneNumber objects that I display. Here's an example of the output of the view:
[Code]....
Notice the naming of these elements: name="existing_phone[labels][6]", name="existing_phone[numbers][6], name="new_phone[labels][]", name="new_phone[numbers][].Back in the Classic ASP days, I recall being able to do something along the lines of:
[Code]....
And that would give me a 2d array of phone numbers to work with. This doesn't seem to work in .NET. Has anyone tried to do something similar that can point me in the right direction?For new phones, I should simply be able to iterate through each item and insert into the database. For existing phones, I should be able to update (or delete if the label or number are blank) records based off of the id number supplied in the array.OR..if anyone has a better, alternate solution, I'm open to something else.
i have a problem with creating dovs based on the data in the xml file. What i need to do is to create a page where the xml file is loaded and if the give Node has childnodes it should be displayed as a link and after clicking a span or a div with childnode's value should appear under it and afte a second click it should "fold" back. I van use the __postback function from js but the problem is in the dymanic creation of the "child" divs. A portion of the xml file:
<Car name = "Ford">
<Type Name = "Escort">
<Description>Some description of the car</Description>
</Type>
<Type Name = "Puma">
</Type>
</Car>
Given the sample above the value "Escort" should be displayed on page as a link and after clicking a div containing value of the Description node should appear but value "Puma" should appear in normal text as it doesn't have children.
I have a form with a bunch of labels and images on it. Is there a way I can capture parts of that form into an images file (jpg/bmp, etc)? Ideally I could specify the x-y coordinates, and save that to a jpg.
View 3 RepliesAs you know froms could lead to accessbility issues and unlike PHP when I was dealing with it, everything in ASP.NET we can say is wrapped inside a form. As you know not every elements is a form element and from accessbility point of view the screen readers have what is called 'forms mode' which only interact with form elements. Can anyone calrify why is that in ASP.NET?

I have a URL /products/search where Products is the controller and Search is the action. This url contains a search form whose action attribute is (and should always be) /products/search eg;
<%using( Html.BeginForm( "search", "products", FormMethod.Post))
This works ok until I introduce paging in the search results. For example if I search for "t" I get a paged list. So on page 2 my url looks like this :
/products/search/t/2
It shows page 2 of the result set for the search "t". The problem is that the form action is now also /products/search/t/2. I want the form to always post to /products/search.
My routes are :routes.MapRoute( "Products search",
"products/search/{query}/{page}",
new { controller = "Products", action = "Search", query = "", page = 1 });
routes.MapRoute( "Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "" });
How can I force Html.BeginForm(), or more specifically Url.Action( "Search", "Products"), to ignore the /query/page in the url?
I have a form with certain elements, input boxes, check boxes etc. I need to encrypt the names of these input boxes and check boxes. I'm currently using a Rijndael encryption/decryption method through c# however this is making the encrypted names too long to be passed in a post. Is there a better way to get decent encrypted names? my purpose is to have the names encrypted before the post happens so if someone views the code behind the names are already encrypted.

I have an asp.net page with several list boxes. I would like to include some javascript on the page that allows a user to drag individual list elements from one box to another. On a normal web page, the script to do this is reasonably simple, however, with the element IDs generated by ASP.NET, I don't know what identifiers to have my script look up?
View 3 RepliesAs I iterate through a DataTable object, I need to check each of its DataRow objects against the items in a generic string List. I found a blog post using the List's Find method along with a delegate, but whereas that example has a separate class (Person), I'm attempting something like the following using an instance of the string object:
// My definition of the List object.
List<string> lstAccountNumbers = new List<string>();
...
// I populate the List via its Add method.
...
foreach (DataRow drCurrentRow in dtMyDataTable.Rows)
{
if (lstAccounts.Find(delegate(string sAccountNumber) { return sAccountNumber == drCurrentRow["AccountNumber"]; })
{
Found_DoSomething();
}
else
{
NotFound_DoSomethingElse();
}
}
However, with this syntax I'm receiving "Cannot implicitly convert type 'string' to 'bool'" for the if block. what I'm doing wrong and how best to accomplish what I'm trying to do?
I am working on some ASP.NET web forms which involves some dynamic generation, and I need to add some onClick helpers on the client side. I have a basic outline of something working, except for one huge problem.
There are multiple HTML tables, each generated by a different ASP.NET web control. Each table can contain overlapping field names, which is causing a problem with my JQuery click event handlers. The click event handler is linking to unintended form fields in addition to the intended form field.
I have provided a simplified sample version of the code below. This code is trying to set the value of textbox box1 when a particular radiobutton is selected in the table with id=thing1. Obviously, the jquery code will be triggered for the form fields in both tables.
The tables are dynamically added to the webpage based upon different conditions. It is possible that no tables will be loaded, only 1 table, or both tables might load. In the future, other tables could be added. Each table comes from a different .net web control.
Other than renaming the form fields to make sure they are unique across all user controls, is there a way to have JQuery act only on the intended form fields? In other words, could the table ID be incorporated into the JQuery code in a manner that does not become a nightmare to maintain later?

In php you can access field by $field = $_POST["field"]
$field["name"] and $field["age"] are simply arrays containing names and ages.
I'm building a shopping cart page that could potentially contain dozens of separate items. Each item has a collapsible panel that contains several form elements that can be used to customize it. Most of the cart is wrapped in an UpdatePanel so that I can avoid a full postback when the user makes changes. When there are many items in the cart, there are of course many many postback elements, all of which are included in the raw form post, even though each post is really only triggered by the change of a single element
