Save EditItemTemplate DropDownList To Database?
Apr 15, 2011
I have a Entity Data Model which abstracts an underlying MSSQL database. I have an EntityDataSource which is wired up to a GridView. The GridView has a number of columns - most are BoundFields, but one is an EditItemTemplate. Inside of this template I've placed the following[code]...
The code executes okay and I can click edit and change the selected dropdownlist, but when I click the Update button in the GridView it doesn't update the value in the database with the datavaluefield value from the edititemtemplate. How can I get it to save the selected value from the edititemtemplate to the database?

In the 2nd step of the wizard, I have a dropdownlist that is populated from the db. when I go to the
3rd step RegisterUser.ActiveStepChanged event if fired. In there I save the data to the db. My
textboxes are saving properly but my the vb code isn't pulling the selectedIndex/Value from the
dropdown.

I have a bit of code where you can add a new field using an add button, which enable the asp:EditItemTemplate, but the thing is that this adds the field at the bottom of the list, making the user have to scroll down if there is enough items already in the ListView. How can I make the new item appear on top of the list?
ASP.NET CODE
<asp:ListView ID="[...]" runat="server" DataSource=<% [...] %> >
<LayoutTemplate>
[...]
</LayoutTemplate>
<ItemTemplate>

I'm a newbie in asp.net. When using FormView, there is a big amount of code in ItemTemplate, EditItemTemplate and InsertItemTemplate which is almost identical.
[Code]...
ListView allows the use of LayoutTemplate - but I didn't see any examples that insert this kind of code in LayoutTemplate. And inserting this code in LayoutTemplate would result in an error.DetailView allows to produce code automatically but I'd like to use a specific design (for ex. using "fieldset" that encompasses some fields).

I have an Web application that retrieves some db info and send it out to an html table. All created on the fly in vb code behind. For every post (row) in the db I also fill puts an instance of a Dropdownlist with items read from the db. That means that for every row I read from the database I read the same db info into the Dropdownlist (see the skeleton example below). A lot of overhead I think. It must be possible to create the Dropdownlist once before the loop and copy from that instance in the loop.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim cboCombo2 As DropDownList
Dim i As Integer

How to query a record in vb.net using combo or textbox via linq to sql like the search engine? Just like when you search in google or youtube, once you typed in the initial string on the textbox or combo box it will show a drop-down list. I tried to use it in my application using linq method but the problem is it would duplicate on the first string that you entered on the dropdownlist if that record exist on your database after you press the space key. I used the code below which duplicates the records on the drop-down list when you type in your string after the space key.
I just want it to be like in any search engine that when you type in the string or your initial string, it will display on the drop-down list all the records from the database that contains the string you entered without duplication. In my case, I'm trying to query a name from my database. This is how it should work, For example, if you type an initial string in the textbox or combo box a named 'Mark', it should display all the names from the database containing 'Mark' into the drop-down list before it changes into its final string that you entered.
Here is the codes I used:
Private Sub ComboBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles
ComboBox1.TextChanged
Dim db As New MultipleDatabaseOperationDataContext
Dim search As String
search = ComboBox1.Text

I have a checkbox in my application,when the checkbox is checked then i want to fetch the data from the database and add it to the dropdownlist of the combobox.Again when the checkbox is unchecked then i want to ramove all the data from the dropdownlist of the combobox.
I did this
Private Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If CheckBox1.Checked = True Then
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=Etech.mdb")
[CODE]...
When the checkbox is checked then the data is added from the database to the dropdownlist of the combobox but when i uncheck it then the data is not removed from the dropdownlist of the combobox. In the above code i think i need to add an else condition to remove the data from the dropdownlist of the combobox and make it empty when the checkbox is unchecked.......but i cant give the proper else condition in the above code.

I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table

Modifying data with the ListView's EditItemTemplate by programmatically settings its DataSource property and calling its DataBind method. I don't have option to use data source control for ListView. All ListViews are bound with data from code-behind. So, I have to handle the Edit/Update mode of ListView manually. [Code]

Visual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnChooseList.Click
Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:desktop"
[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database. The imported lists won't always be in the same column order.The end result needs to be that the data in my datagridview will be altered by the user and then saved to the correct columns in my database.

1. It doesn't accept modifications to the existing datas in the column & rows. (Error : Updates require a ValidCommand......)
2. Remove button does not delete the data in the database. It only works in the runtime.
