Pass Array To Client Side For Display?

Mar 20, 2010

I have an array which contains around 50-200 hyperlinks. How can I pass this array to the client-side so that I can iterate through the array and display each hyperlinks as a list item?
The array will be stored in 'Application' as it's system wide and rarely changes. Could there be a more efficient way of achieving the hyperlinks as a list?

Web Forms :: Add The Numbers To An Array In Javascript?

Jan 19, 2011

I know that I can declare an array using the following method, but assume there is an easier way.

var elem as new Array();

elem[0] = 1;
elem[1] = 2;
elem[2] = 3;
and so on......

Is there a short cut to simply adding the numbers 0 -20 to an array, and is there a shotcut to adding the 20 nuumbers minus a few such as 3, 9, and 17?

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

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" />

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">
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

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.

Gridview Cell Value And Array List

Nov 25, 2010

When I am tryng to pass the gridview cell values to an array everything is perfect but the array is empty after executing the code. When I see through debug mode the index of selected row also is fine, i.e. when I select two rows using checkbox among 1000 the count shows exactly 2 in the array but the data is empty. I'm not able to get the cell value from the gridview.

protected void Button2008_Click(object sender, EventArgs e)
ArrayList checkedItems = new ArrayList();
foreach (GridViewRow row in this.GridView1.Rows)
if (((CheckBox)row.FindControl("cbRows")).Checked == true)
Session["CheckedItems"] = checkedItems;
Response.Redirect("About.aspx", true);

WCF Service Return And Array Instead Of A List <T>?

Mar 26, 2010

In the web servce I say

public List<Customer> GetCustomers()
PR1Entities dc = new PR1Entities();
var q = (from x in dc.Customers
select x).ToList();
return q;
(customer is a entity object)

Then I generate the proxy when I add the service.. and in the reference.cd it say

public wcf1.ServiceReference1.Customer[] GetCustomers() {
return base.Channel.GetCustomers();

WHY IS IT AN ARRAY? I asked for a List.

C# - Array, Dictionary Or List In A Session?

Feb 5, 2010

What would be the most efficient way of storing a set of values in a session? I'm guessing it's either a List/Array or Dictionary. Basically, when a user selects an item from a DropDownList, a value (between 1 and N where N <= 20) is sent back to the server. I'd then like this value to be used as an index (if using arrays) or key (if using a dictionary) within the session. I don't want the value to be seen by the user, hence why it's not stored in the DDL. From what I gather, dictionaries are designed for key-lookups. However, since the scale is quite small, are there any overheads of using a dictionary that could make it less efficient in this case? Each corresponding value is unique to the user, so I've decided to use sessions.
