Web Forms :: Getting An Array Of List From Database To Client Side(javascript Array)?
May 12, 2010
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
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?
I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.
I'm trying to send a bunch of looped records from database to javascript array in codebehind to add overlays to the googlemap markers. So farthe code below only provide me the first marker.
PHP Code:
private void BuildScript(DataTable tbl)     {         String Markers = "";         foreach (DataRow r in tbl.Rows)         {         [code]...
I have create a web page having dynamically created text boxes if i select value in dropdown list,text boxes auto generates .but i want to save all text box values in SQL server database after clicking on submit button using ajax/JSON request
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?
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)
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.
[code]... 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.
I'm having arraylist to add student info but i have to create unique id per record below is my class.Student
objStudent=new Student(123,"Nj");statArray.Add(objStudent)public class Student{ private string name; private int RollId; public string Name { get { return name; } set { name = value; } } public int Id { get { return RollId; } set { RollId = value; } } public Employee(string name, int id) { { this.name=name; this.Id=id; } }
How would I pass an Object or Array to a function using the ICallBackEventHandler (RaisCallbackEvent)? It allows for a string argument only, if you change it to another datatype it error out. Sample Below...
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.
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(); }
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.
n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddl.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) { _btn.ValidationGroup = "G1"; } if (_selectedIndex == 2) { _btn.ValidationGroup = "G2"; } }
i have an string data array which contains data like this
5~kiran 2~ram 1~arun 6~rohan
now a method returns an value like string [] data public string [] names()
{ return data.Toarray() } public class Person { public string Name { get; set; } public int Age { get; set; } ) List<Person> persons = new List<Person>(); string [] names =names();
now i need to copy all the data from an string array to an list<person> and finally bind to grid view
i want to insert checkbox text only if they are checked. .. how to do that ..
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load TextBox1.Text = Request.QueryString("txt") Dim splitted As String() = TextBox1.Text.Split(",") For Each id As String In splitted Dim ctrl As Control = Page.FindControl("checkbox" & id) If Not ctrl Is Nothing Then Dim chkbox As CheckBox = DirectCast(ctrl, CheckBox) chkbox.Enabled = False Dim arrList As New ArrayList() 'populate the list with some temp values arrList.Add(CheckBox1.Text) arrList.Add(CheckBox2.Text) 'databind the list to our repeater Repeater1.DataSource = arrList Repeater1.DataBind() End If Next End Sub
This code will add all checkboxes whether it is checked or not !
so that only checked checkboxes would be added in array list
