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 want to compare my database value with my new updated value. what should i do ? e.g : on page load i am excuting one procedure which bring 10 columns and fill it against the 10 fields using for loop on the page. then i am changing value of two columns. ok. when i press update button then there is one more procedure which updates all the new and old columns into database. Its working fine. just i want to know that, should i update only two columns(which are modified) insted of updating all 10 columns ? Is there any csharp code that brings my page load columns into array and then compare it with new ones and updates only those columns which are mismatch with array. i am not sure but there is some way to do this.
View 4 Replies 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.

View 1 RepliesI 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 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

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.
<td
style="width: 454px">
<asp:ListBox
ID="lbox_ConstructionType"

<asp:TextBox
ID="tbox_Ctype"
runat="server"
Text='<%# Bind("ConstructionTypeID") %>'></asp:TextBox></td>

i have a sortedlist who values contain a Product objects. i wish to set the Quantity property of a selected Product object ( from gridview) when the Quantity field changes?

note. i have converted to a list(of product) to bind to gridview. then update the sortedlist values
I have a textbox that takes an integer value, and a submit button that when clicked passes the value to a detailsview to display the database record at that index.
What I'd like to do is, when the button is clicked, compare the number to the keys in the detailsview's datasource so that if the record ID doesn't exist, I can display a label telling the user that the ID# doesn't exist.
How would I go about doing this? Is there some sort of compare method for the datakeynames property?
I'm a little new in ASP.NET, so i don't know how the .NET machine fully works..I'm using two strategies to solve my problem, both invoked by a Button.Click event, but i don't know which one is better..My worries are about the server overload and page load time.This is the regular approuch i've used..

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:
