Getting List Box Items Added Through Jquery In Code Behind?
Jan 31, 2011
I have a asp.net list box control in which i populate items using Jquery by using some code like ..
$("#MylistBox").append("<option value='somevalue'>Someitem</option>
dynamically . but in code behind when i use MylistBox.Items is always showing Count 0 no matter how much items add.
So I have a number of dropdown select list controls populated as part of a repeater. They might contain overlapping data, meaning that the first d d list control will have selections:
a b c
Second one:
c d e
Third one:
d e h
and so on.
So what I would like to do is to srart removing the duplicate items from the reset of drop down controls once the user starts selecting those. I intend to use jQuery for this.
I got a list of checkboxes on my form, and a jquery script that catch a button click to get all the selected items (in an array) and post to a controller action.
This is my script: (yes A, looked at your sample but cannot get this to work)
[Code]....
That alert will print out correctly (like 1,3,5).
However when the above post hit my controller action, "selectedInvestments" are null, which I can't figure out why (back to my tekpub jquery videos, can't go on like this)
On adding items in it ,shows an error: "Dropdownlist does not allow multiple selection."But when i tries to print the selected item it shows null exception.
I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
Is it possible to select values from a List, where the items contain in a different list aswell?for example;
[Code]....
What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
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
I do not know how this has started but when creating new pages in a web project using vb.net coding, when I add any control such as a button or something else and then do to the vb code page for it, I click the dropdown on the left and it does not show the controls. What would cause this? I am using a master page with the page and the controls are going into the content sections. If I add a line like:
Code:
[code]....
then I have events. But in another peoject I do not have to do this. Is there a reason why? Maybe a setting that was changed? I'm using VS2008 in vb.net language.
I've got a dropdown whose values i filled based on some control selection, when I select buy new option it fills in with the new price and if I select buy old one it fills with the price of old items.now filling of drop down is working fine but when i press the submit button I try to get the selected Item but it always return seectedIndex as 0?
I am outputting the content of a page from a subroutine. The weird thing is, the code behind is writing this to my aspx page. <asp:Hyperlink ID="HyperLink1" runat="server" CssClass="HoverMenuText">more</asp:HyperLink> When the page is viewed live, the hyperlink is not a hyperlink because using the browser to "View Source", the html shows the exact same line! It wasn't converted to the format like "<a id="ctl00_ContentPlaceHolder1_HyperLinkHover">HoverMenuTest</a>" So for some reason, the server is not converting this asp control to an html control. Any ideas why it wouldn't do that?
The controls show up fine on the page, but they don't show up when I view source, nor can I access them from the code behind.If I add the controls in the on_init method, they work. But I have some business rules driving changes to the list of controls itself that require I fire the add method elsewhere. Has anyone seen this before? I'm away from work so I can't copy the exact code.
I have two terrible ideas for how to get it working. One involves some jQuery and a set of hidden controls holding a big array of integers; the other is run the method on_init AND on my other events so the controls at least show up. Both smell like ugly hacks.
I am using Jquery and Ajax to add new record into the database. After successfully insert the record, I want the listview I have to automatically append the previous added record.
The record can be added successfuly into the database and the only problem is I want them to be display in my listview after I click submit button. So is there any solution for this?
