Forms Data Controls :: Multiselection In Listbox C#?
Jul 13, 2010
I want to select the multiple items in the listbox.....for eg in my listbox there are five itemsapple,pear,lotus,red,blue.on button click i want to select two items from the listbox.
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'm trying to auto-populate a listbox of zip codes from a database table state_zipcode_plans based on the state a user selects from the previous listbox. I'm getting the error: Must declare the scalar variable @state_code.
how I can read the selected field from the listbox?I have MSAccess table attached to the app.I can get to the properties, but I don't know which property gets me the data of the specific field.In VB it would be "listbox1.Column(x)", where 'x' represents the column number in the listbox1.I am using Microsoft Visual Web Developer 2010 Express
I have a detailsview which is used to input data into an SQL database. Some of the fields contain drop down menus which are populated from the database.
I also have a form that allows the user to select mutiple values from a listbox (populated from an sql database) by moving the required items from one list box containing all the available items into a second one containing the selected items. There is also a text box which is used to filter on the available items. When this is passed through to a stored procedure to be put into the database, it is passed as a comma delimited string containing all the selected values.
This works fine on a separate form, however I would like to include it in one of the fields of the detailsview. This creates a BC30451: Name 'ListBox1' is not declared error. I have looked for hours on the internet to try and resolve this but cannot find what I need for how to declare the list for use within the detailsview.
Here is the code for both the working multiselect form and the code for when I have tried to integrate it into the detailsview:
I have a ListView which has Product Code,Desc, ColorCode, Size and Quantity as the columns as well as a checkbox
The listbox sits within a panel.
The user enters the quantity and checks the item(s) they wish to purchase. They accept their selection by clicking a button the sit within the ItemView
Once they have made their order and clicked the button I want to make the panel disappear and display the items on the page.
how to iterate through the Listview and how to grab the items and close the panel
I have a search option which a person can use a multi select listbox. I have it coded so it would loop through to see if its selected or not. I also have a stored procedure where the sql statement is coded for the select statement. For some reason, its not populating my gridview. Where am I doing wrong? Below is the code and stored procedure. [Code]....
I have a web page with a gridview & formview (master/detail relationship) combo. On page load the gridview shows all records from a SQL table. On my page I have a button that when clicked shows the formview in Insert mode to allow users to add a new record to the data. I have also added a column to my gridview that has a link. When a user clicks this link it hides the gridview and shows the formview in edit mode with the detail from the record selected from the gridview.
In my formview I am using a listbox control to allow users to select multiple values. The choices in the listbox are populated by a SQL data table. I have successfully written code to post the selected listbox values to my SQL data field during Insert. When the user selects a record to edit I have code in the databound event to select values in the listbox from the choices based on the value in the sql data field. This works as well. My problem is that I cannot figure out the correct code to update my SqL data when a user is editing the record and makes changes to the selected listbox value. I have included my design code for my listbox in my formview edittemplate and also my behind code that I have attempted.
I managed to insert items in a listbox (as a cart). The data inserted in something like this 3x T-Shirt @ $40.00 each Black Small 4x Trunks @ $ 12.95 each Blue Large I want to be able to insert this as a chunk of code in 1 column in .mdf
I have listbox which retrieve data from database as follow
[Code]....
if the user want to access editpage , and he made some changes on listbox2 by removeing or adding more rows , it should be edited in database I need the best way to edit it , the way that I am doing now is deleting all record and then entring new record from listbox2 , but sometime it's adding duplicate record.
I have a listbox that I want to check to see if the current row value already exists in another listbox. How can I hide/preven row from being added to listbox at databind/databound?
I am creating an editable DataList and I am wondering if a Listview can be added in the ItemTemplate and the EditItemTemplate.I added it but cannot access the control from the code-behind page to populate it.
I have a scenario in which I want to display Multiple Columns in ListBox. I am working in .NET 1.1I am binding data to ListBox from DataTable. Example: I have Two Columns in Table ID, Name. So I want to display ID and Name in a Single LISTBOX.
Using VB.Net/Asp.Net 2008, web app with Master page.I have a content page where all of the content is wrapped in an UpdatePanel that uses a UserControl called GetEmployee.ascx that I created.
In the user control I have a listbox filled with employeeIDs for the DataValueField, in fact for testing to make sure I'm getting the ID I temporarily set the DataTextField to employeeID also. Anyways I keep getting "" error saying I have not selected anything even when I do so I put a breakpoint and set a watch to find out selectedIndex, value and item and nothing.
after the user selects an employee they should click on the "select employee" button so I have some code there to find out which employee was selected. I have events setup in the GetEmployee.ascx user control to get the value selected:
[Code]....
and I have a breakpoint and it hits the "selectedIndexChanged" event first so I put a watch there and see the following.
I have two ListBoxes. I can move items from one list box to the other. I have an Insertcommand for inserting added values from the "ActivePrograms" list box to a db.
my problem is that it inserts only one item when sometimes the user added multiple items.
how do I insert all existing items from "ActivePrograms" list box?:
second issue: how do I make sure the insert command go through the list of items in the listbox and makes sure these rows does mot already exsited in the db? in other words insert only NEW values for that 'Id' value
How would I retreive the following numeric id value from a xml response, to a dropdownlistbox?
[Code]....
The following does not work for newContactID
var xmlResponse = proxy.ProcessClientAction(xmlRequest);var parsedXmlResopnse = XElement.Parse(xmlResponse);
I would like to have the ContactRecID's value stored in the variable newContactID based on the selection of the user. So if the user selects the the person "Sam" then 4033 should be stored in newContactId.
