Web Forms :: Setting A Dropdownlist That Is Binded To An Sqldatasource To A Particular Datavaluefield Id?
Apr 30, 2010So I have a major issue and cannot find any solution online to solve it excepting one that is singlistviews. But i am also encounting some probs with listviews since i am not sure of to use it.Anyways so my major issue is that I have drop down lists that are being populated by a sqldatasource. Users are filling out a form selecting values in the drop down list which is fine, the prob exists with editing a record. I have the dataValuefield to be the Id of the data and the selected item in the dropdownlist id is being stored in a database. So I have the data in the database that is the Id of the selected item however I cant use the dropdownlist1.selectValue ='idNo' since that only works with listitems.
How can i access the dynamic rows in a dropdownlist that is being populated by a sqldatasource and set the selected item to a particular item?Any insight is greatly welcome. Even how to use listviews

C# - DropDownList: DataTextField, DataValueField - DataEnabledField?
Jun 1, 2010I'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.)
Dropdownlist Not Behaving Properly When Datavaluefield And Datatextfield Are Same?
Mar 24, 2011I 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 + ";" +

Move DataTextField & DataValueField From Listbox1 To Listbox2?
Jul 9, 2010I 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
