Asp.net - Creating A Dynamic Dropdown, After A Selection Has Been Made

Oct 6, 2011

I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)

For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)

When the brand is selected I want another dropdown to appear under it with new chocies

For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)

And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.

Sql - Dynamic Dropdown Based On Radio Selection

Nov 2, 2009

We have a GUI that displays a radio selection box (3 options) that are the three sites where our hospitals are. We need to dropdown located on the form to fill with only the locations based on the selected radio option.

Here is the code behind we have so far (sorry, VB)

[Code]....

For the record the Location dropdown is currently databound but its a static SELECT statement which brings us all the locations but we'd prefer it to be cleaner if it only returned the locations based on Site. We are using Visual Basic 2008 Express Edition for development.

Asp.net - Get Selected Row Index Of Dynamic Dropdown List Selection?

May 29, 2009

I know the question is a little choppy and perhaps misleading,but I have a gridview with dropdownlists on the rows. I created an AddHandler and a Delegate for the SelectedIndexChanged and it gets to the sub. Here is the code for that:

AddHandler ddlmgr.SelectedIndexChanged, AddressOf ddlmgr_SelectedIndexChanged
Public Delegate Sub DropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As DropDownList_SelectedIndexChanged)

Protected Sub ddlmgr_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)

End Sub How can i get the row's Id if GridView_RowCommand is not called?

Build A Program That Has A Dropdown Menu?

Oct 18, 2011

I am trying to build a program that has a Dropdown menu (Combobox) where you select between a list of items like

xbox
ps2
ps3
wii

then once you select one of the options the program will bring you to a new window (In the same window) with a new box that has a list depending on which word you chose earlier. As an example.

If you chose xbox on the first window it will bring you to a window with a new list like

fighting game 2009
fighting game 2010
fighting game 2011

then if you select fighting game 2011 you would get another window that showed a list that had a list of characters from that game.

Guy One
Funny Hat Guy
Big Nose Guy
Dead Guy
Beast Thing
Funny Turtle Thing

Then in the new window you get a selection of options for the character you selected.

Special Skills
Combo Moves
Unlockable Content

Then if you select one of those you get a new window that has the lists. for example.

If you chose Special Skills show the list of special skills like the following.

Uppercut: Down + Y
Face Smasher: Back, Forward, B

and maybe beside the list of moves it could display an image of a Screen shot that shows the move (Or not if it is too complicated).

Dropdown Menu As Program Arguments

Jun 6, 2011

I decided to make a small app that runs another app with arguments. I think the best way to do it was selecting one option from a dropdown menu and using this option as an argument to run the app.

The clean part I did: Public Class LanguageSelectDialog
Private Sub LanguageSelectDialog_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

[Code]....

Since I'm just trying out, I've made an blank app just for testing purposes. What I need to do in order to pass the selected option as argument? I'm using VisualStudio 2010.

Other 2 things that I didn't figured out:

- how can I make a form unresizable?

- how can I make the dropdown menu not editable?

Asp.net - Populate A Dropdown List With Data?

Jun 9, 2009

I have a dropdownlist that I want to populate with a specific value and specific text. I'm not using a datasource but I am manually making a connection and retrieving data in code. How can I populate this dropdownlist? If I read the data with a datareader and increment an array I only get either the value or the text. This is what I have so far, but it is completely wrong:

//connection string etc goes here
Dbcmd2.CommandText = "select dept,deptname from table"
Dim dr As SqlClient.SqlDataReader[code]....

How can I get this to work without having to create a class object for Department? Is there anyway or should I create the class object?

DataGridView Row Selection By VB Program?

Jun 6, 2010

I am using VB 2008. My DataGridView could contain a thousand rows in alphabetic order and I want my users to be able to find a row quickly without them having to scan through many rows. I could provide a row of buttons captioned A to Z or I could provide a search field in a textBox but in either case my program would have to find a particular row and focus on that row. Question one: Does DataGridView have a function that searches for a a particular value in a specified column? I have found no alternative to sequentially searching through the list. Question two: Once I have identified the index to a particular row, how can I make that row become the selected row?

There is so much to DataGridView that somebody should write a book specially about DataGridView. I would buy it.
