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.
I am successfully able to add new items to a drop down list using Javascript.
The script I am using is
function FillJavaScriptValues() {
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)

having trouble only adding the checkboxstatus's that are checked to the gridview.
Protected Sub atasks_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim tasknamelist As New List(Of Boolean)
For Each row As GridViewRow In GridView1.Rows
' Selects the text from the TextBox
Dim checkboxstatus As CheckBox = CType(row.FindControl("tasknamebox"), CheckBox)
tasknamelist.Add(checkboxstatus.Checked) [code]....
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 have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load

Is it possible to set tab index value for list items of ASP.Net RadioButtonList control.
View 1 RepliesI'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:
<asp:DropDownList ID="ddlFilter" runat="server" >
<asp:PlaceHolder ID="ListItemPlaceholder" runat="server"/>
</asp:DropDownList>
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:
<mytag:MyControl Mode="DropDown" runat="server">
<ListItemTemplate>
<asp:ListItem Text="C" Value="c"></asp:ListItem>
<asp:ListItem Text="E" Value="e"></asp:ListItem>
<asp:ListItem Text="B" Value="b"></asp:ListItem>
</ListItemTemplate>
</myTag:MyControl>
I know I can do this by dynamically adding the ListItems in the page code behind, but I'd like to avoid that if possible.
I am getting this error yet I know it to be untrue.This is the code:
ddlPartnerOrganisation.DataSource = agency.AgencyGetListOfEYDN();
string temp = ddlPartnerOrganisation.SelectedValue.ToString();
ddlPartnerOrganisation.DataValueField = "AgencyID"
;
ddlPartnerOrganisation.DataTextField = "AgencyName"
;
ddlPartnerOrganisation.DataBind();
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.

View 4 RepliesI 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?
I'm adding a dynamically built set of checkboxes to an asp.net page from the code behind with something like this in a recursive fashion:
pnlPageAccessList.Controls.Add(myCheckboxControl);
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?
