How do I bind data from an Excel file named Book1.xlsx in Column A to a dropdownlist? I've tried like this:
Code:
connExcel.Open()
cmdExcel.CommandText = "SELECT distinct BCName From [Sheet1$] where BCName <> '' and ProjectName like 'Total%';"
oda.SelectCommand = cmdExcel
oda.Fill(dt2)
connExcel.Close()
dropdown1.DataSource = dt2
dropdown1.DataBind()
But the dropdown is filled with "System.Data.DataRowView" for all the 5 lines in the dropdown. How do I get the values shown instead of this? It must be some formatting of dt2 I think.

I have a GridView control that has a SQLDataSource.
The GridView provides me with a list of musical artists (from the tblArtists)
In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.
(An example of the data in that field would be "7", which upon lookup would mean Classical in the
tblGenreList table.)
What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.
Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList
Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.
Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.
My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.
Is this possible?
In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB

I have a table and 7 column name.
I bind the 7 column name in one dropdownlist.
Now the problem is,how do I extract the data value in a dropdownlist?
For example,
Dropdownlist contain 7 column name
-subject_name
-subject_code
-venue
-time
-seat_no
-admission_no
-subject_id
when I click the subject_name,I want it to appear in a gridview
Example
Math|9.00-10.00|Hall|18|09090J|...
Below is my current codes which I have a problem.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source= EN\SQLEXPRESS;" + "Initial Catalog=ms;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "SELECT '" + dd_list.SelectedValue+ "' FROM examtimetable ";
adapSel = new SqlDataAdapter(mySQL, conn);
conn.Open();
DataSet dsSel = new DataSet();
adapSel.Fill(dsSel);
GridView1.DataSource = dsSel;
GridView1.DataBind();
conn.Close();
}
Previously I have bind 7 column name in my dropdownlist
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
SqlConnection conn = new SqlConnection("Data Source= EN\SQLEXPRESS;" + "Initial Catalog=ms;Integrated Security=SSPI");
SqlCommand sqlCmd = new SqlCommand("select column_name from information_schema.columns where table_name='examtimetable' and COLUMN_NAME not like '%ID'", conn);
conn.Open();
SqlDataReader ds;
ds = sqlCmd.ExecuteReader();
dd_list.Items.Clear();
dd_list.DataSource = ds;
dd_list.DataTextField = "Column_Name";
dd_list.DataValueField = "Column_Name";
dd_list.DataBind();
dd_list.Items.Insert(0, "Select Option");
ds.Close();
conn.Close();
}

I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)
[Code]....
The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:
[Code]....
But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist

cmd = New SqlCommand("Select HeadId,HeadName from Heads Order By HeadName", conn)

reader = cmd.ExecuteReader()
While reader.Read

I was wondering why this doesn't work:
Is it possible to declaratively bind to an Object's property.
<asp:DropDownList id="ddl" runat="server"
DataValueField="Key"
DataTextField="Value.DisplayName" />
Code Behind
var d = new Dictionary<int, MailAddress>();
d.Add(0,new MailAddress("foo@bar.com", "Mr. Foo");
d.Add(1,new MailAddress("bar@foo.com", "Mr. Bar");
ddl.DataSource = d;
ddl.DataBind(); // Error. It doesn't like "DisplayName"
