AJAX :: Parsing Data To ListBox From DropDownList
Mar 19, 2010
I have to parse the data to dropdownlist and then choosed the data from dropdownlist, this data will be appear in listbox. But my problem is when I parse the data to dropdownlist, I used updatepanel. It is no problem. It is okay. And then when I choose the data from dropdownlist, It can't be appear in listbox. Why? I have no idea. My code is :
<asp:UpdatePanel ID="UpdatePanel8" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:DropDownList ID="ddlChoiceRVS" runat="server" AutoPostBack="True" Width="500px"
Enabled="false" onselectedindexchanged="ddlChoiceRVS_SelectedIndexChanged" />
<asp:ListSearchExtender ID="ddlChoiceRVS_ListSearchExtender" runat="server" Enabled="True"
TargetControlID="ddlChoiceRVS">
</asp:ListSearchExtender>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="lb_Edit" EventName="Click" />
</Triggers>
</asp:UpdatePanel>...........................

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:

In other words, when i search "sandra' in textbox and select a Department A , the listbox will show all the sandra from Department A only.

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 been trying to populate either a listbox, dropdownlist, or textarea with a large amount of numbers. I can create the list by manually putting in the numbers I want but that is not what I really want to do. There are too many numbers anyway. Is there a way to use maybe an array and a for next loop to put many numbers in a list where you can scroll down and see each item entry.

I have the following data that basically I only need a few bits of information from:
Resource:X - Y;Z - Å;Type:(all) From Date:

by:Time Include Referring

","Z, X","Y","7/12/2010
12:00:00AM","Time","Patient
Name","Patient ID","Appt.
Type","Phone","Type","DOB "," 7:30
[snip]
The only things I need from this are:
Patients Name
Drs Name
Patients Phone Number
Appt Time
Appt Date
and the rest of the information I can discard. A customer uploads this as a .csv file (even though it really isn't as you can see) and I'd like to parse the needed information and post that to my SQL database and discard the rest. I think I can do this with a dataset but I've never built that before. The fields from the customer will always be the same and the fields I will need will always be the same. Also, the date time has to be in the format of yyyy/mm/dd:hhmm and the phone number always has to have 512 as a prefix. Here is the code I currently have for my site:

I was given an assignment to parse out a text file, without a header record, using only a handful of the 300+ fields supplied. Since there is no header record to define the fields as in a CSV file, I was given these preliminary instructions after creating the HTML page using the file upload control and a few labels and such:
1- create a data table
2- add the columns I want to use to the table
3- save the uploaded file
4- define a stream reader
5- read each row and use MID to extract the data I need
6- write this data to the data table
7- display all the records in a grid view
I've managed to get to step #7 and that's where I'm having trouble. When I look at the data in the grid view, all the fields are in one column, the first column.
I had a little trouble earlier on and a colleague told me to concatenate the parsed fields using a comma and double quotes ("fld1","fld2","fld3"...) which sounded odd but I listened and now, I realize he was leading me down the wrong path.
So:
I used "Dim dtWork as New DataTable"
then "dtWork.Columns.Add("Lastname") for each column I wanted
then saved the file "Dim sPath As Sting="C:..."
defined a stream reader "Dim rdr As New StreamReader(sPath)
Read the rows "Dim sCurrentRow As String = rdr.ReadLine"
and parsed the data "Dim sLastName As String = Mid(sCurrentROw, 3, 25)"
did this for all my fields I wanted and then concatenated each field as described above into a string "Dim sData As String = sLastName & "," & sFirstName & ","....
and added it to the data table "dtWork.Rows.Add(sData)"
So that's the jist of it sans the datasource = dtWork and then the databind. Now, how do I get each parsed field into each respective column the right way?

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?

first i'll describe my problem:
I have payment form with a clients dropdownlist that is populated from a database on form load with:
value field = clientIdtext field = nameId
<asp:DropDownList ID="selClients" runat="server">
</asp:DropDownList>
When user makes a payment, it's necessary to chose a client from selClients, and so i get the clientsId value and build my insert SQL query.
Until here, no problems.
The problem with my UI has started since i had a lot of clients been registered: My dropdownlist became huge and it's taking too much time to load it's contents on page load. Also the dropdownlist area is taking a large area from page screen.
So i tryied a solution with jquery autocomplete plug in. I put a textbox with autocomplete for client name and another hiddenfield to receive the clientId when user select a item.
That solves both problems:
No more large amout of data loaded on page loadThe dropdownlist doesn't take a large area from page screen
But it gave me another problem!
With a textbox, there is a possibility for wrong input client name. So if i don't have a valid clientId in hiddenfield, it will generate a database INSERT exception because it doesn't respect the client table constraint:
payment table REFERS client table
I'm trying to find kind of dropdownlist where the user can type text with autocomplete. Like this, the user will be able to select only data within the possibilities of the dropdownlist and i always will have a valid clientId.
