Web Forms :: Unable To Get The Expected Value From Drop Down List?
Mar 13, 2010
I have a drop down list that is populated with customer IDs. When I write to the db a value of 11 is written for the customer ID 13 when it is chosen from the drop down . I thought this was because I was using the SelectedIndex and how it is 0 based like an array. In the drop down list I choose 13. Id 2 is missing from the drop down list because that record was deleted. I thought these two things together explained the two digit discrepancy with the what i got when I used the Selected Index property. I then decided to use the SelectedValue property which should give me 13 when I choose 13 in the drop down list.
The same thing happens when I use the SelectedValue property. I used the SelectedValue property and chose 13 in the drop down list. This also gave me 11 as the value that was written to the db. This makes no sense to me. If I chose 13 in the drop down then 13 should have been written to the db when using the SelectedValue.
I'm using a Sql Data Source temporarily to populate this with the CustID.

I was building an application for a project with .NET 3.5 and I noticed a weird behaviour of the List.Add method:
I have built my own class to organize data pulled from a database, and I use a while cycle to iterate through it.
However, when I List.Add(item), the whole content of the list is substituted with the last content pulled.
An example:
Suppose you have 3 users in a DB, each one identified with an ID and a username:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
and you have a "Users" class defined as
public class Users
{
private Int32 iD;
private String username;
public Int32 ID
{
get { return iD; }
set { iD = value; }
}
public String Username
{
get { return username; }
set { username = value; }
}
}
So you write this function:
[... SQL definitions - sdr is a SqlDataReader ...]
List<Users> userlist = new List<Users>();
if (sdr.HasRows) //There are users
{
Users user = new Users();
while (sdr.Read())
{
user.ID = sdr.GetInt32(0);
user.username = sdr.GetString(1);
userlist.Add(user);
}
}
What you expect (I expect) is userlist containing:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
What I actually get is, instead
| ID | username |
| 3 | Paul |
| 3 | Paul |
| 3 | Paul |

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.
Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.

I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.
I have also set the Text property of the Drop down list
Text='<%DataBinder.Eval(Container.DataItem,"Employee_ID")%>'>
However, it is not populating the DropDown list, what should I do?

I want to make a button that changes the value in a dropdown list (dropdown populated from SQLdatasource)This sounds strange i know but i have 4 dropdowns each hidden by panels, unless the preceeding dropdown's value is changed from it's initial value. So i make a selection from my first dropdown list & a postback occurrs triggering the next panel (and as such
the dropdown list) to become visible, this occurs again until eventually my users will see 4 drop down boxes...(all required field vals etc)

I am trying to write a web page where i have to select an item form a drop down list.
I am using linq to sql to get the data from the database.the strange thing is that i can register the data to the drop down list but when i select one of them the drop down list lets me to the first item. I set post back = true because i want to update the page every time an item get selected. I wrote a really simple code to check what was going wrong but still...no success. Below i am bringing the code i wrote.

I have combined my SQL result to display in drop down list in such manner:
" SAV 123-423-231 "
" CUR 234-234-212"
User selects which account to view. So if the user selects SAV 123-423-231, I have to pass in the bank account number. How do I do that?
By split? I tried doing this:
ddlAcc.text.split(" ")

Iam working on a web based form where I have a DDL to which I have attached a field validator which is not working. It should function in such a way that whenever the DDL is left to blank, it gives user an error. I have introduced that BLANK in the DDL using ListItem as I found that as the easisest way out.
<asp:DropDownList ID="DropDownList4" runat="server"
DataSourceID="AccessDataSource4" DataTextField="myState"
DataValueField="myState" AppendDataBoundItems="true">
<asp:ListItem Selected = "True" Text = "" Value = ""></asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="reqState" runat="server"
ErrorMessage="RequiredFieldValidator" Text="Required Field"
InitialValue="None" ControlToValidate="DropDownList4" Display="Dynamic">
</asp:RequiredFieldValidator>

How can I make the first item in a drop down list non selectable. I want this first list-item to show up when the page is opened and want to populate the rest of the DDL from a backend DB. I don't want this default first item in the list to be selected (just want to show it as a default value)
I want it to look something like this.
Choose a State: (Appearing on the top of DDL, but cant be selected)

I have just got the login control working, and would like to grab the currently logged in username (I'm guessing via the loginname control), and then have the Drop Down list on the default.aspx select the matching name. The names don't exactly match so, I could hard code compare them via a select case or if statement, but the problem is I don't how to get the logged in username into a variable, and I don't know how to have the drop down list (which is databound) select the record.
