I'm adding ListItems to a ListBox from two controls, both are DropDownLists. The ListItem has the properties ListItem.SelectedItem and ListItem.SelectedValue, but I also want the ListBox to keep track of which DropDownList the ListItem came from.What would be the best way to do this?
View 4 RepliesI have some files listed on a listbox and want to upload them to the server. The values doesn't need to be selected. But I can't even get it working. Below is my source code:

Where is the bug in the code above?
I'm currently trying to move through all the values added to a listbox by the user, however, I want to retrieve the actual value of each item in the listbox and not the text.
I've gotten so far with the code below, but that only gets the text and not the value.

How would I go about getting the value for each item in the collection?
Hey what i am trying to do is i have a listbox with some simple values in it
1
2
3
and what i want to do is add a value that has multiple values to it...for instance i want a value = All DEV which will represent many values in itself so that once ALL DEV is selected it actually has many different numbers assigned to it. Can this be done? I understand that the value 1 has just one value behind it, same as 2 and 3 but I want the All DEV one to have multiple values behind it such as 5,6,7,8 for clicking just the ALL DEV selection.
I am developing a Webpage that gives the user selection criterial before running a report. There is a asp.net ListBox that I need to get the selected values from. It is obviously a multi select listbox.
I need to pass the selected values as a comma separated string to a parameter used in an SQL query of the ObjectDataSource for the report. I was hoping some how to get the selected items, and load their value into a string array and then use the join( stringArray , "," ) to get the selected values into a string to send as a parameter to my objectdatasource but I cant seem to figure this out.. Ideally if code worked my way I would want to do something like this: Declare StringArray for each selected item in Mylistbox Add selected value to StringArray Set parameter = join( StringArray , "," ) Obviously this is what I need syntax for.. I pretty much just need to know how to get a string array or all selected values.

I try to set selected values in html.listbox.
I retun in my model multiSelectList:
model.SelectedDepartments = dto.Departments;
model.DepartmentsItems = new MultiSelectList(
_DepartmentRepository.GetAll(),
"Id", "IdentityNumber",
new int[] { 2 });
return model;
In html page i have these tags:
<label for="dto_Departments"><%= Html.GlobalResource("DiagnosticGroup", "DiagnosticGroup.Departments")%></label>
<%= Html.ListBox("dto.Departments", Model.DepartmentsItems, new { id = "dto_Departments" })%>
When I'm debugging program MultiSelectList contains selected second item in list.
I have a set of values in a listbox on an ASP webform. I can select items, and in code, if the user selects some row from a different grid, the listbox shows the correct value. The user can also select a different value. All of this appears to work as I would expect. However, that's as far as it goes. At first, the SelectedIndexChanged event wasn't firing. I determined that was because I hadn't hooked up the event handler, which I did with this:
Code:
asp:ListBox ID="AgencyListBox" runat="server" OnSelectedIndexChanged="AgencyListBox_SelectedIndexChanged" EnableViewState = "true">
(the EnableViewState wasn't part of that solution. I added it later)
Now, the SelectedIndexChanged event fires, though it doesn't fire when the user selects something, it changes later, possibly in response to an AutoPostBack, since I read that will trigger the SelectedIndexChanged event. That's fine with me, either time will work ok. However, the SelectedIndex itself is always -1, as if nothing was ever selected. In fact, though I can see visually that something is selected, I have yet to figure out what that was, or how to access the index, the text, or anything even the fact that something was selected.
I want to display panels based on the check boxes selected on the dynamic checkbox list control. I have been able to dynamically build the check box but have no idea on how to access its checked propety. This is what I am doing but getting error on Request.Form On page load wrote this code.
protected void Page_Load(object sender, EventArgs e)
{
int i;
int chkboxCount = Request.Form("chklist1").Count;
for ( i = 1; i < chkboxCount)
{
String valueChkbox = Request.Form["chklist1"];
}
}
I have a Listbox getting populated when the page loads itself and also in postbacks. Some items are already selected in that listbox even when the page loads or postbacks. I have to select one or more items in that textbox in addition to the selected one.
Till this point, it works perfectly, but the problem is that when i click an "update" button to save the newly added items, then also the page postbacks and so the list box get populated again. This will loose the newly selected items and none of the newly selected items will be saved.
So what should i do in order not to loose the newly selected items when i click the "update" button.
Note:- I need to populate the listbox on postbacks also. So the population of that listbox on postbacks cannot be discarded.
I am having 2 list box in my form. I am adding some values from 1st list box to 2nd one. What i need is i would like to save the data in the list box in sql table.
View 6 Repliesi have a list box (listbox1) populated with some values.i also have a table with some values.I'd like to show values from table which are NOT IN listbox1.here's a code. I see what the problem is. Just can't understand what is the solution.If I have one value in listbox it works fine, but if more than 1 it messed up, since it tries loop several times.
[Code]....it works fine. The only thing: If I want to update some properties of item, but do not update name(just leave name the way it was) it still fires the validation, and my update cannot pass validation since this name is already exists.i have a listbox populated with values from linqdatasource (or from datacontext using code-behind) Also I have formview which allows to insert new values to database.When I insert new value in the database, this value doesn't show up in listbox until I recompile project/restart browser. When i refresh page nothing happen. Only old values are visible. Id like to have more dynamic page. I tried updatepanels. Maybe I need somehow refresh database connection first?
have an ASP.Net page with two ListBox components, rendered in the browser as <select> lists. I'm using jQuery to move elements from one list to another by manipulating the DOM. I then select all elements with the mouse and postback the form. That way, all the list elements are posted with the form.When I submit the form, in my button_save() event handler, the Request.Form[<<listbox ID>>] values are correct. However the ListBox controls themselves, specifically their Items collections, do not reflect my changes.I've also used Fiddler to modify the select items and submit the form. Same as above, the ListBox values are no different, though the Request.Form values are. Would anyone know what's going on or what incorrect assumptions I'm making?

I'm using a List Box to get multiple values that will be used in a query.I can loop over the List Box and create the string.i.e. 'blue','red','purple'The string is used in the query: SELECT * FROM TABLE1 WHERE COLOR IN('blue','red','purple'). Is there a way to parametrize multiple values? @COLOR='blue','red','purple'What will be the best practice to prevent SQL injections in this scenario?
View 10 RepliesI 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)
