I have a dropdown list where i wanted to display months in reversed quarterly format based on the current month.
for eg. if this is the month of January 2011.. so the list has to display from the previous quarter onwards....
the dropdown list has to display:-
Oct 2010 - Dec 2010
Jul 2010 - Sep 2010
Apr 2010 - Jun 2010
Jan 2010 - Mar 2010
and so on...
How can i generate dropdown lists based on what has been selected in the checckbox list. Below is an example of what i need. if the user selects the options day, lotID and waferID, then 3 cascading dropdown lists should be displayed. And then a gridview displays data based on what has been chosen in the dropdown lists.
Day

SlotID
WaferID
VendorID
ToolID
LocationDetected
ProcessStep

the following content I created a table (Workers) with two columns(username,userid). Now i have Dropdownlist and textbox. Dropdownlist for Userid, Textbox for Username. If i click on the userid in dropdownlist, then the particular username should get displayed on the textbox. For this i have tried codings.
private void DropDownList()
{
OleDbConnection databaseConnection = new OleDbConnection(ConfigurationManager.ConnectionStrings[1].ConnectionString);
databaseConnection.Open();
OleDbDataAdapter dataAdapter = new OleDbDataAdapter("Select userid from workers", databaseConnection);
DataTable dataTable = new DataTable();
dataAdapter.Fill(dataTable);
DropDownListMaterials.DataSource = dataTable;
DropDownListMaterials.DataTextField = "userid";
DropDownListMaterials.DataValueField = "userid";
DropDownListMaterials.DataBind();
}
protected void DropDownListMaterials_SelectedIndexChanged(object sender, EventArgs e)
{
OleDbConnection databaseConnection = new OleDbConnection(ConfigurationManager.ConnectionStrings[1].ConnectionString);
databaseConnection.Open();
OleDbCommand MyCommand = new OleDbCommand("select username from gridview where userid=('" + DropDownListMaterials.SelectedItem + "')", databaseConnection);
TextBoxUsername.Text =
}
private void DropDownList()
I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.

View 4 RepliesI'm using a List in ASP.NET 3.5/C# to filter an existing list of dates (about 20 in total) on a specific month.
So if a user selects a year of 2010 (ddlFromYear.SelectedItem.Text == 2010) then the returned list would consist of only 8 months because we only go up to August.
My question is - how do I output the DateTime as an int, or even preferrably a Month, e.g. "August". That way when I'm binding another DropDown I can list out all the months (January, February...) which as I mentioned would be determined by years (2009, 2010...)
int yearSelected;
bool success = Int32.TryParse(ddlFromYear.SelectedItem.Text, out yearSelected);

I have a form that needs to display 3 dropdown lists, one for my client type, then, based on the selection, my second list shows the clients for that type, and then based on the client name, my third dropdown box shows the contacts for that client. The first dropdown list one being a normal html.dropdownlist, and the other 2 being CascadingDropdownLists.
I have followed Stephen Walther's method 1 located at [URL]. If I select my client type, then my client names in my second dropdown shows perfectly, but when I choose my client name, the third dropdown does not work. When I view my page source, all my contacts are listed in my <select> control, but my dropdown box stays blank. Did anyone ever get a third dropdown to work?

View 3 RepliesI have 2 drop down lists.I have a very simple dropdown list #1 that diplays a title and holds an id value which is a GUID.I know it is getting this value and sending this value as I tested sending it to a label.I have the dropdown list #1 to autopostback to dropdown list #2 that "Is supposed to get" another title and value based on the GUID value of the first dropdown list. for some reason it wont return anything. I have done 100's of these but never based off a guid value.I assume the value needs to be converted to guid before selecting it in the second dropdown list.How can I do this? or is there something I am missing?

I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
