Asp.net - HTML.DropDownList Values From Multiple Sources?

Jul 27, 2010

In ASP.NET MVC, is it possible to fill the list of values of a Html.DropDownList from multiple data sources along with multiple manually entered values?Basically, I envision it being formated like the below using something along the lines of OPTGROUP:

**Group 1**
Manual Item 1
Manual Item 2
**Group 2**

[code]....

I've thought about using a view on the DB and getting the data from that, however, I've not really the faintest how to lay it out like above using helpers and to pass the data to it from multiple sources.

Select Multiple Values In DropdownList In Asp.net With VB?

Jan 20, 2012

I am creating a page in which I need to show a drop down List. From this drop down List a user can select multiple values. I know I could use a check box list like:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" style="margin-right: 158px">
<asp:ListItem>Value 1</asp:ListItem>
<asp:ListItem>Value 2</asp:ListItem>

[code]....

but if there are more than 50 or so values then that will consume a lot of space on the page and will look odd. So kindly tell me how can I select multiple values from drop down list or if there any alternatives so that I can select multiple values and show many records on a minimum space but not a grid?

Jan 13, 2009

ok so I am trying to grab a bunch of phone numbers from my html page. I have successfully grabed the first one but I dont know how to get it to loop around and grab the next one and list them out into a listbox. here is the code I have for getting the first value, but how can I make it go in a loop.

Getting Multiple Copy Sources?

Jan 5, 2011

As a college project, I'm making a basic web browser, which contains all of the basic functions such as copy, cut, paste, delete, load a webpage, save as, print, etc. At the moment, I can copy from the HTML document, but I can't actually copy from the URL input bar. How do I do it so that when I click "Copy" it will copy the text to the clipboard, no matter what field has focus. So for example, if text in the URL bar has been selected, and the URL bar has focus, then copy that text to the clipboard; but if something in the HTML document has been selected, then copy that.At the moment, I'm using this to copy, cut, paste, etc. from the HTML document:

BrowserWindow.Document.ExecCommand("Copy", False, Clipboard)

Add Multiple Data Sources To ListView?

Sep 15, 2011

Currently, I am trying to make a table, which retrieves failed products and passed products from an Entity with LINQ.

Lets assume I've done that, but have 2 lists, A regular List(Of String), and a SortedDictionary(Of String, int32) (To hold the product, and the number of times the testpoint has failed).

Now, when I want to output them to ListView, in a Webform, how can I make it, so that List(Of String), will be output on the listview, and the SortedDictionary, be output after the List(Of String)?

EDIT: Although I could just add the SortedDictionary values to the end of the List aswell, but how would I go around doing so? Because I will create a listview with 2 columns, one which holds the descriptive text, and then a List(Of String) value. And the SortedDictionary would follow, requiring two columns.

Bind Multiple Sources Of Data?

Jun 13, 2012

It's been a long while since I've done any VB.Net coding and need to bind some data to a form. I have multiple tables that share some common primary/foreign keys and need to easily be able to update them.

For example, I have a table with an ObjectID, TypeID, AreaID, and several other fields. When doing my layout, I need the TypeID (found only in the main table) to be a distinct value in a comboBox, and in the ComboBox which contains the Area to be the Area Description (from the main table tied to the Area table via the Area ID).

Using Single Binding Navigator With Multiple Data Sources

Feb 10, 2010

I have a winforms app access a database with 6 tables. Out of 6, I am showing 3 tables on three different tabs on my Form.

I have separate binding source for each of the three tables.

Handle Events And Notifications From Multiple Sources To A Main Form In .net?

Sep 23, 2011

I have a vb.net application in which there is a main form. There are around 10 classes each having their own functionalities like tcpactions, fileactions, serialport actions etc. The user interacts with the main form and does certain actions which will invoke the methods in these classes. Now I have a notifications textarea in the mainform and i want to show the current action being performed in those classes and their results in the notifications area.

for example when a user clicks a "Start Process" Button in the form i invoke the method "launchprocess" in a class "ProcessActions". Now this method tries to launch about 7 different process and after launching it sends notification such as "process 1 launched" or if it fails it sends notifications such as "process 1 launch failed".

I currently use event handlers and use them to show notifications but with the amount of events i have to handle it is getting cumbersome and i might have to add even more classes in the future. So is there a better way of handling notifications from other classes.

Seems most of the examples I find are c#, so in some cases I'm left scratching my head... to make a long story short, I'm simply trying to output the selectList of items to a drop-down within my view:

All I'm trying to do now is simply output my "SelectList" within a HTML.DROPDOWNLIST() in my view.When doing a step through, my list items are showing within my "Return view(viewmodel)" watch, but I'm stuck with performing the output.

Asp.net - DropDownList After Postback All Values/index Lost

Jun 11, 2012

I'm running into a little problem with a gridview and a dropdownlist. I can get the dropdownlist to load initially, but when it autopostback's it returns with no value. I am populating the dropdownlist in the RowEditing sub. I'm guessing that I must somehow rebind in the RowDataBound sub, but don't know how to go about it. If I try to find the control's SelectedValue I end up with nothing.

Dynamicly Displayed DropDownList If Multiple Entry Exists In Table?

Apr 9, 2012

I'm trying to create an option to select a specific entry in a SQL table if multiples exists. The Sub listed below is for a textbox (MOTxt) and a button (GotMO) for checking an MO# to pull from SQL. Based on the number entered, will populate other text boxes on the page with that row's data. There are exceptions to this, where the MONumber will be entered more than once with different data associated with each entry. So, here's my situation. If we have a duplicate MONumber listed in the table, it will populate the textboxes with the first entry it finds for an update.I would like to create a dynamic dropdownlist (that displays only if multiples are found) displaying the 'Name' field entries for each MONumber found, then once the correct name is selected from that list, to then populate the textboxes with that selected datarow.Here's my code behind:

Protected Sub GotMONum_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles GotMO.Click
Dim da As New SqlDataAdapter

Exclude Multiple Values In Sum Depending On Values In 2 Columns In SSRS 2005?

Apr 21, 2009

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?
