Web Forms :: Adding Item To Listbox From Another Listbox Taking Way Too Long?
Mar 4, 2010I have two list boxes, one has a list of available users (about 1500 items) and the other is blank. There is a button to add the seleted items from the first list box to the second one. Both of these listboxes are within an update panel and for some reason it takes over 20 seconds for the items to show up in the second listbox.
Is this normal? Is there an alternate, faster way of doing this?

VS 2010 - Adding Items To ListBox
Jul 12, 2011I've never built an ASP.NET application. At my work, we have a bunch of different PDFs, Word and Excel documents, HTML pages, etc, all in one folder. My boss has tasked me with creating a web app to combine all of these items into one interface.
Among the things I'm adding, I need to convert a VB app I made. All the app does is scan our servers for log files and displays them in a ListBox.
Before I start importing the classes and setting up the code, I decided to just add a ListBox to the page and add a ListItem during page load.
VB.NET Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Me.lbLogs.Items.Add(New ListItem("Test", "C"))End Sub
But, an exception is thrown when I try to run it.
The example I'm using there is the example shown on MSDN. Why this is occurring?

VS 2010 - Adding Index To Listbox Values During Population
Jun 27, 2014I have a SQL table used by a third party application that I have very little control over. The table contains a list of assemblies and their corresponding serial numbers. The tables primary key is a composite of the assembly number and serial number. There is no field I can use, reliably as an index.
I have an application I'm working on that pulls all the serial numbers from that table based on the assembly in a SQL View. I've then written code that pulls the serial numbers from that view based on the part number in a textbox on the form. That functionality works fine but I had both my datatextfield and datavaluefield set to the serial number. I've created another empty listbox that I would like to populate from a serial number or serial numbers being selected in the first. That is not working, I believe, because there is no index for the list.
My question is...How can I add an index value to each serial number as they populate from the SQL table. I've included the code below that I have pulling the serial number values.
This is an ASP.net VB webform.
Code:
Private Sub FillSnAvailList()
Dim strconnect1 As String = ("Data Source=MyDataSource")
Dim con1 As New SqlConnection(strconnect1)
con1.Open()
Dim cmd1 As New SqlCommand("SELECT [sPartNum], [SerialNum] FROM [V_MaxSerialNum] WHERE ([sPartNum] = @sPartNum)", con1)
[Code] ....
Web Forms :: Error When Adding To Listbox / Object Reference Not Set To An Instance Of An Object
Feb 19, 2010I have just recently converted my VB code to C# and now having this error when I try to add an item to my listbox, and the value is coming from the item page. I get the error at this segement:
lstboxCart.Items.Add(cartItem.Display());
My listbox is supposed to add the product's name, quantity, and price onto one row.
Here's what I have so far:

My guess is that the source of the problem could be in the foreach loop from my cart class, shouldn't I be using that for arrays only? If I need to post any markup code or any other class, let me know.
C# - Can't Get Value In Code-behind After JQuery Appends To Asp:Listbox
Feb 22, 2011've created 2 asp:listbox... asp:ListboxFrom and asp:ListboxTo. When I double click on the item on ListboxFrom it moves (appends) the item to ListboxTo... So everything works fine till here. But when I click on the submit button to process everything I don't get the selected items in my code-behind for the listboxes. I debugged on Page_Init and Page_load but it restores the default controlstate values..
1) How can I get the values in code-behind ? so the state of asp:listbox as it is added client-side code.
2) another question: when it appends to the ListboxTo the items are selected per default (they are blue). How can I avoid this?
below is the simple JQuery code I use in aspx,
<asp:ListBox ID="listboxFrom" SelectionMode="Multiple" />
<asp:ListBox ID="listboxTo" SelectionMode="Multiple" />
$(function() {
$('select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxFrom]').bind("dblclick", function() {
$("select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxFrom] option:selected").appendTo("#dnn_ctr658_ViewAgenda_Invoer_listboxTo");
});
$('select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxTo]').bind("dblclick", function() {
$("select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxTo] option:selected").appendTo("#dnn_ctr658_ViewAgenda_Invoer_listboxFrom");
});
});

Web Forms :: Adding A Control Through Code?
Aug 15, 2010I'm trying to essentially add a dropdownlist control array to a from from the code-behind but I am getting an HttpException error saying that it must be placed inside a form tag with runat=server. How can I do this? This is the code I have right now for it:

Forms Data Controls :: ListBox, Array List / Update The Listbox Content?
Mar 26, 2011I am designing a program that will let me enter the name of an item to swap and adds the swap to an array list when a button Add is pressed. Once the item is added to the array list a Sub Procedure should be called which displays the contents of the array list in a list box.
The system will also allow me to remove items from the array list using a Remove button
followed by updating array list.
I have done some part which puts item into the listbox1 which i named lstSwapList.I would need some assistance on the Sub Procedure to display the Value or Description on the other listbox2 which i have also named lstContent,if a value is selected from the listbox1.
I would also want to know how to update the Listbox content,However i hv added a sample of the way i guess it may be.
Any complete solution from anybody on the Sub Procedure and the Update Swap procedure will be greately appreciated.
The script below is what i have done so far.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged
End Sub
Protected Sub lstSwapList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstSwapList.SelectedIndexChanged
End Sub
Protected Sub btnAddSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddSwap.Click
Dim SwapValue As String = "Sixty Pounds"
Dim Counter As Integer = 8
Dim SwapN0 As Integer
lstSwapList.Items.Add(SwapValue)
lstSwapList.Items.Add(Counter)
lstSwapList.Items.Add(New ListItem("300", "1"))
lstSwapList.Items.Add(New ListItem("ASP.Net", "2"))
lstSwapList.Items.Add(New ListItem("Programming", "3"))
SwapN0 = lstSwapList.SelectedValue
For Counter = 0 To -1
SwapN0 = lstContent.Items.Count
Next
End Sub
Protected Sub btnDeleteSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDeleteSwap.Click
lstSwapList.Items.Remove(lstSwapList.SelectedValue)
End Sub
Protected Sub btnUpdateSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateSwap.Click
End Sub
End Class

Web Forms :: Adding Code To Page Before Server Processing?
Feb 18, 2010I was wondering if there was anyway to populate the page with asp.net code like "<asp:Repeater ID="rptProducts" runat="server">MORE_CODE</asp:Repeater>" and then have the server use that code on the page. I'm not sure if i'm making sense. Like writing the asp.net front end code to the page dynamically before the .net engine generates the output html.

Web Forms :: Error Adding Item To List Box When Trying To Convert From VB.Net Code
Feb 24, 2010I inherited an application written for VB.Net and am converting it over to ASP.Net, with VB as the back end. I have a data pull that adds values to a new instance of a class, then adds the item to a listbox. It worked great in the VB.Net version, but I get the following error in the Visual Studio Text Editor when I try to use the code:
Overload resolution failed because no accessible 'Add' can be called with these arguments:
'Public Sub Add(Item As System.Web.UI.WebControls.ListItem)':Value of type 'MyItem' cannot be converted to System.Web.UI.WebControls.ListItem'.
'Public Sub Add(Item as String)':Value of type 'MyItem' cannot be converted to String.
I have played around with the code quite a bit and have been researching online, but I'm just drawing a blank here.
I put the class("MyItem") in the "App_Code" folder in a file called "MyItem.vb". The class code is as follows:

Forms Data Controls :: Adding Spaces In A String Which Is Generated Dynamically In C# Code?
Jul 20, 2010I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.
Forms Data Controls :: Dynamic DetailsView - Adding Template Field By Code?
Feb 11, 2010I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.
