Web Forms :: Fill Listbox Using Webservice / Via Control
Mar 25, 2011
I have a number of dropdownlists which use cascading dropdownlist / webservices. All fine. Now user wants last dropdown to be multi-select. So I want to replace the last dropdownlist with a listbox. But there is no cascadinglistbox. I'm looking for a straight-forward solution if possible. Either how to fill the listbox with the existing webservice which fills the last dropdownlist, or - is it possible to use the contrents of the last dropdown as a datasource for the listbox? I thought maybe hide the last dropdown and loop through its contents to fill the listbox.

I have an ASP.Net website, that uses a MySQL database. First of all, because the Connect/Net of MySQL doesn't install on PC (reason unknown, no error, it just doesn't work) I'm using ODBC for the connection. I've written some nice wrapper classes for using the database, and it's all working ok.
But now I'm adding a little Silverlight application to my website (first thing I'm making with WCF/Silverlight, without actually reading any tutorial, so let's hope for the best).
Now this application won't be anything fancy, it's only for the administrators, to read the logs, and change some configuration settings, etc, nothing fancy at all. But what it has to do is retrieve data from the services.
What I've done is a setup a service reference, and it works like a blessing, but now I'm trying to read the logs from the service, and I'm getting in trouble, because my class was never built to serialize to XML, first issue. And secondly I wouldn't know how to bind the retrieved data at the client to the datagrid.
I'm going to parse the recordset at the server so that I'll be sending a class containing an array of columns, and a multi-dimensional with the data to the client, now that's not much of a problem, I'm just mentioning it so that you can either improve or keep in mind what the data will look like.
My question: How would I bind that retrieved data to a plain <sdk:DataGrid>?

Maybe the question has already be posted, but I didn't find it. I have in my web page two controls: a dropdownlist and a listbox My goal is to fill the listbox with values from my database depending on what I have selected in my dropdownlist. I wouldlike to use the CascadingDropDown component for that. Is that possible? (I tried on my own and I get this error message
Exception Details: System.InvalidCastException: Unable to cast object of type 'System.Web.UI.WebControls.ListBox' to type 'System.Web.UI.WebControls.DropDownList'. I think it's when i tried to fill the listbox with this function:

I'm moving itmes from one ASP.NET ListBox control to another ListBox control from client-side. It works on the client-side but when I tried to count items in destination ListBox on the server-side, it's always nothing. Below, is the jQuery code used to add/remove items from ListBox control.
[Code].....
I know that we can add/remove items from ListBox from server-side. But I'd like to get it done from client-side. Why there isn't anything in the destination ListBox when counting the items from the code-behind, eventhough the items are added from the client-side already.

I expected that clicking on different items in the control would cause each to highlight, but when I click a new item the highlight moves to that item, and previously selected highlight is removed. Is this how the control is supposed to work?
<asp:ListBox ID="lbxMulti" runat="server" DataSourceID="adsMembers"
DataTextField="Name" DataValueField="ID" SelectionMode="Multiple">

I 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
=======================================
Sub UpdateSwap(ByVal valueA As String, ByVal ValueBAs String, ByVal ValueC As Integer, ByVal ValueD As Date)

I 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?

I am working in asp.net 4.0(VS2010)
I have two values 1. Maximum Amount 2. Reached Amount
I have to show a box with two colors(Dark Green and Light Green) and based on the % of reached amount i have to increase the reached amount color. Also inside the box i have show the label with reached amount.
Let us take an example of Max Amount : $50 and Current Reached Amount : $25. So now my box should be filled with Dark Green color half the size of box and Light Green filled with half size of box and have to show the label as "Reached amount: $25" inside the box.
Then tomorrow if reached amount is $35 then Dark green color should be increased and light green should be reduced based on the % of increase. as like this based on increased and decreased calculation the colors have to filled.

I am working on a screen where in it has a typical 2 listboxes & 2 buttons(add/remove), so when these buttons are clicked the items have to move from one listbox to another. its all working fine with javascript.but the issue is, I am not able to get the items of the 2nd listbox in the codebehind. I tried with html & asp.net listbox controls. I even tried to access the listbox using Request.Form["ControlName"] - which gives a null value.In the listbox1 the data's are coming from database.The data's choose from listbox1 will be moved to listbox2. And again i have to update this data to one of database table.

I do have a listbox control and a button to update values of the list box with few other values of the form to the database. If i select 3 values in the listbox, it has to update the database in 3 rows (Unique for Listbox value) with the other value being the same. I use a details value for inserting values.

I have 2 image controls like this where I will declare 2 images in the .css file. The images has the exact width and height as the image controls, so this is correct.
1. For Image1, the image is not seen entirely in the image control in designview (only a corner of the image is seen) but when debug the page it fills out the control ? How can it be entirely seen in the imagecontrol in designview?
2. For Image2, there is a red cross on the image both in designview and in debugmode, wonder why, as the .css declare an image to the control and how this cross can be taken away ?
