Web Forms :: Use The DataTextField For A Label Control?
Aug 5, 2010
<asp:SqlDataSource ID="sql_Region" runat="server" ConnectionString="<%$ ConnectionStrings:Test %>" SelectCommand="SELECT Number, Name FROM table_Region WHERE Number = @Number" SelectCommandType="Text">
<asp:DropDownList ID="dd_Region" runat="server" DataSourceID="sql_Region" DataTextField="Name" DataValueField="Number" /> Ok, I have this dropdownlist and I want to use the DataTextField for a label control.
Something like this. I want to show the region as a label but I only could get the DataValueField value not DataTextField value. Does anybody knows? <asp:Label ID="label_Region" runat="server" /> <C#>
label_Region.Text = dd_Region.SelectedValue.ToString(); <--I know by doing this, I can get the DataValueField but. label_Region.Text = (DataTextField) <<--How do I get this value? I want to show the region name not the region number

I have a list <Department> say Company.Departments with object Manager and ManagerId, ManagerName as property of Manager. I would like to fill the dropdownlist with managers as below
ddlManager.DataSource = Company.Departments;
ddlManager.DataTextField = "ManagerName";
ddlManager.DataValueField = "ManagerId";
Is there a way to specify the property of an object in DataTextField or I need to copy a Manager list for the DataSource?

I am not sure if my subject is phrased properly but here is what I am getting problems with.I have a detailsview which had about 3 dropdownlist (ddl) on it. The DDL's works fine when I insert a new record or I try to edit an existing record.But when I just want to view the data in the detailsview it displays the primary keys (DataValueFields) instead of the associated DataTextField Value.

I would rather not magic string my DataTextField/Values on the dropdownlist after setting up the source as a List collection of objects.
I was thinking I could use the DataSource properties but it doesn't seem to like the couple of ways I tried.
WORKS BUT NOT IDEAL
//set the datasource to the returned List<Cart>
this.cartDdl.DataSource = CartManager.Load(WebProfile.Current.UserName);
//set the DataValueField to the Cart.ID property
this.cartDdl.DataValueField = "ID";//would rather use the obj property Cart.ID
//set the DataTextField to the Cart.Description property
this.cartDdl.DataTextField = "Description";//would rather use the obj property Cart.Description
//Bind the ddl to the datasource
this.cartDdl.DataBind();
HOW I WOULD THINK IT COULD WORK this.cartDdl.DataValueField = ((Cart)this.cartDdl.DataSourceObject).ID; this.cartDdl.DataTextField = ((Cart)this.cartDdl.DataSourceObject).Description;

I have a dataset which I am binding to a listbox. However, I want to combine two of the fields to make up the DataTextField. Is this possible, or am I going to have to loop through the Data Rows?
lstAddressDropdown.DataSource = dsAddress;
lstAddressDropdown.DataTextField = "StreetAddress" + "Place";
lstAddressDropdown.DataBind();
lstAddressDropdown.Items.Insert(0, new ListItem("Please select"));
It's worth noting that the dataset comes back from a web service so I can't change any stored procedure to combine the columns there.

Is there a way to display several records in the datatextfield in a asp dropdownlist? I know the fix when populating the dropdownlist from a datagrid was to edit your SQL query but the values I am receiving are sent via an XML string. The idea would be to display a name, price, and date in the dropdown text. Currently I am getting the following error: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'MonetaryValueServiceType' While using UPSDropDown.DataTextField = "MonetaryValue" & "ServiceType" Is there a work around to do this? The only other option is to use radio buttons (which are also a nightmare).

I'm currently working with a control that inherits from DropDownList (it has some extra functionality that isn't really relevant to this question, but it gives me a nice place to implement the extra stuff I'm gonig to discuss).
We're using data binding, with the DataTextField and DataValueField working absolutely fine. However, I find myself in need of a similar field that will control whether or not the item is enabled. (I've already overridden the RenderContents method of the control so it properly renders non-Enabled items, since DropDownList doesn't do this by default.)
Thus I'd like to know how to override the DropDownList's data binding so it acts exactly as normal, except a further field from each DataSource item is applied to each ListItem's Enabled property.
(NB: the field I'll be binding to isn't a straight boolean, and doesn't have an explicit/implicit cast to boolean, so I'll probably be "passing" it as a string.)

I have a State class defined like this:
Public Class State
Public Property StateId As Integer
Public Property Name As Dictionary(Of Integer, String)
End Class
Name(x) contains the state name in different languages. I get a collection of State from the method StateManager.GetAllStates() and I want to bind this collection to a DropDownList. The problem is that I can't find how to set the DataTextField property to let's say stateList.Name(1) which is the english name of my state.
Dim stateList As StateCollection = StateManager.GetAllStates()
Me.DataSource = stateList
Me.DataValueField = "StateId"
Me.DataTextField = "Name(1).Value" <-- Problem here
Me.DataBind()

I have a dropdownlist for which I am loading data from excel. Excel has 2 columns Product and Email. Data in Product column is binding to DataTextField and Email column to DataValueField. The dropdown works fine when email is different for different product but when email has same value for different product then whatever I select, on postback the selected value changes to the first item of the same email value.
Below are the sample data in Excel to show the behavior of dropdown
Example 1. (Drop down works fine for this example)
Product Email
iPad prashanth364@gmail.com
iPhone 3G prashanth364@yahoo.co.in
iPhone4 prashanth364@in.com
Example 2. (In the example below, whatever I select (iPad or iPhone 3G or iPhone4) on post back the dropdown selected value will be iPad)
Product Email
iPad prashanth364@gmail.com
iPhone 3G prashanth364@gmail.com
iPhone4 prashanth364@gmail.com
Example 3. (In the example below, when I select iPad the dropdown works fine but when I select iPhone 3G or iPhone4 on post back the dropdown selected value will be iPhone 3G. Basically, on selecting iPhone4 here, on post back it shows iPhone 3G)
Product Email
iPad prashanth364@yahoo.co.in
iPhone 3G prashanth364@gmail.com
iPhone4 prashanth364@gmail.com
Below is the function where I am loaidng the data from excel to dropdown private void ExtractFromExcelInitial()
{
// Put user code to initialize the page here
// Create connection string variable. Modify the "Data Source"
// parameter as appropriate for your environment.
string ExcelFilePath = Server.MapPath("~/ProductExcel") + "\ProductEmail.xls";
String sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + ExcelFilePath + ";" +
"Extended Properties=Excel 8.0;";

I have 2 listboxes....
Listbox1 has
DataTextField="Category"
DataValueField="CategoryID"
(coming from Dropdownlist)
I want to move a Item (a Category) from listbox1 to listbox2...but how do I move this Category Plus the CategoryID to lisbox2 (CategoryID should not be visible but still be associated with Category in Listbox2)
So I want the newly added Categories to be visible in Listbox2 ..but their CategoryID's must be invisible...but still be associated with their Category....
and when I save these Categories from Listbox2 to the Database.....its should be the CategoryID's that should go into the Database.....not the actual Category
So to explain again in a different way
I want to Move a selected DataTextField & its DataValueField from Listbox1 to listbox2
then only the array of DataValueField must be saved to Database

i have a Label control, and i would like to insert the value into the database, but i would like the value to be times 2, so for example, the value of my label control is 20, so if i added code that withdrew the 20 from the label, how could i make it take the value x2, so it would get 40 instead of 20, and if i had 5, it would get 10, if i had 30, it would get 60, etc etc, how may i do this?
