Is it possible to show multiple columns and headers inside of a combo box/dropdown list in asp.net and show related columns values, for an example, if I click on a country name then it should show me all the cities for that country and clicking on city name should show me all the related places.

Employee emp = new Employee();
comHandledBySQt.DataSource = emp.GetDataFromTable("1");
comHandledBySQt.DisplayMember = "FirstName";
The above code displays drop list of employees first names in a combo box. I want first name and last name to be displayed. How can i do it?I tried to include two columns FirstName and LastName as below but didn't work.
comHandledBySQt.DisplayMember = "FirstName" + " " + "LastName";
I have simple columns and their respective sums. However, I exclude 1 particular value from each sum, like so [code]...
Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".
Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?
i.e. How do I exclude multiple values, depending on values in 2 columns in SSRS 2005?
Situation Overview I'm using Ext.NET GridPanel to display a list of projects which has tasks (i call it Sprints) inside it assigned to some user and a status. So I get this kind of relation:
SprintOwner -> UserID
SprintStatus -> SprintStatusID
In my GridPanel I display my sprints grouped by projects and I use the relationships to show their names instead of their IDs (SprintStatusName and UserName). It's in portuguese but I find it useful to show:

lets see if I can explain my self. I have 2 fields in the country the country table "CountryName & Countrycoed" . My question is how to display the Contrycoed in a textbox after selecting the country in a combobox. For example if I select Canada in the combo I would like CND to be displayed in the textbox. This is the SQL I have to load the combobox
comType.CommandText = String.Format("select CountryName,Countrycoed from Country ")
I have created a link using VS2008 and MS Access 2007.In my database, assume that I have ID, First Name, Last Name, Gender
------------------------
1 John Smith Male
2 Michael Jackson Male
3 Alicia Keys Female
------------------------
These are the data I have in my database.In my form, assume that I have
ID [Combo Box]
First Name [Text Box]
Last Name [Text Box]
Gender [Text Box]
Now, I have 3 ID in my combo box. If I choose [1] in my combo box, I want the rest of my test box show [John] [Smith] [Male].When I choose [2] in my combo box again, it will show [Michael] [Jackson] [Male].
I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

View 1 RepliesI am trying to create a unit converter program. At the moment I'm trying to populate my combo box with results that have been calculated. I have two sets of results to display. I want them displayed side by side and have been trying very hard to do this. So far I've managed to get the result to display but only the original unit, it's start, increment and end value. Not the converted unit, start, increment and end value.
Then I managed to display both the original inputs and the converted inputs but they were showing directly below one another instead of being seperated into two seperate columns, i.e. original input, start, increment and end and the converted unit, start, increment etc.
This is the code snippet I am working with:
lstTableResult.Text = "" + (FormatNumber(lcInputValue, CInt(mdDecPlaces))), "" + (FormatNumber(lcResult, CInt(mdDecPlaces)))
The code above is incorrect and shows errors, i.e. is asking for end of statement.
The code below works, but it is only one code line, I've just split into two to make it work... not what I actually want.
lstTableResult.Items.Add(FormatNumber(lcInputValue, CInt(mdDecPlaces)))
lstTableResult.Items.Add(FormatNumber(lcResult, CInt(mdDecPlaces)))

I am familiar with getting a selected value from a combo box but what about if you wanted to get all the values from a combo box then store those values in an array or list. The combo box would be data bound to a source and have an ID as the value member. So How would I get all the values from the combo box.

I have two comboboxes in my form (cbAdresse & cbVerwaltung). Choosing the value in the first combo, i get the value from the table into the textbox txtAdID. Now i try to use the value in the txtAdID as the parameter for the SQL command selecting the values from the table (tblVerwaltung). These values must be added to the second combo (cbVerwaltung). So i use the following code for the SQL Compact Client:[code]Using this code i get the following value in my combo cbVerwaltung: "System.Data.DataViewManagerListItemTypeDescriptor".[code]
View 3 RepliesI have a combo box that is tied to a binding source that loads a list of users from a table. Currently the list of users is a List of String object type. When a user selects one of the users from the drop down, a list is filtered down based on the selection. To do that I currently have to requery the User Table to grab the UserID column of the user selected, which seems a bit inefficient to me.
Is there a way that I can assign a custom object with two properties (UserName, UserID) and have only the User Name is displayed and when I have to filter the list, I already have the UserID, so there is no need to requery the database.

I am working with Vb.net and have a form with a combo Box. On load the form is loaded with one of the following details depending on what is stored in the database; Cancelled, Processed and Failed.
TxtColStage.Items.Add("Cancelled")
TxtColStage.Items.Add("Processed")
TxtColStage.Items.Add("Failed")
Then I have an update button and when the user drops down the list he/she can select between Cancelled/Processed/Failed. I want to be able to grey out or disable Processed and Failed, so that when the user updates the field he/she can ONLY update with the Cancelled option ONLY.

I know how to create an array and loop through it normally - but what if I need a multi-column array. e.g. usually I might do something like:
For Each row in NameofArray
Dim name as String = row
Response.Write("Hello " & name & "!")
Next
But what if I want to do something like:
For Each row in NameofArray
Dim name as String = row.name
Dim age as Integer = row.age
Response.Write("Hello " & name & "! You are " & age & " years old!"
Next
If this isn't possible with an array?
