MVC :: Set Selected Values In Html.listbox?
Jul 26, 2010
I try to set selected values in html.listbox.
I retun in my model multiSelectList:
model.SelectedDepartments = dto.Departments;
model.DepartmentsItems = new MultiSelectList(
_DepartmentRepository.GetAll(),
"Id", "IdentityNumber",
new int[] { 2 });
return model;
In html page i have these tags:
<label for="dto_Departments"><%= Html.GlobalResource("DiagnosticGroup", "DiagnosticGroup.Departments")%></label>
<%= Html.ListBox("dto.Departments", Model.DepartmentsItems, new { id = "dto_Departments" })%>
When I'm debugging program MultiSelectList contains selected second item in list.

I am developing a Webpage that gives the user selection criterial before running a report. There is a asp.net ListBox that I need to get the selected values from. It is obviously a multi select listbox.
I need to pass the selected values as a comma separated string to a parameter used in an SQL query of the ObjectDataSource for the report. I was hoping some how to get the selected items, and load their value into a string array and then use the join( stringArray , "," ) to get the selected values into a string to send as a parameter to my objectdatasource but I cant seem to figure this out.. Ideally if code worked my way I would want to do something like this: Declare StringArray for each selected item in Mylistbox Add selected value to StringArray Set parameter = join( StringArray , "," ) Obviously this is what I need syntax for.. I pretty much just need to know how to get a string array or all selected values.

I have a Listbox getting populated when the page loads itself and also in postbacks. Some items are already selected in that listbox even when the page loads or postbacks. I have to select one or more items in that textbox in addition to the selected one.
Till this point, it works perfectly, but the problem is that when i click an "update" button to save the newly added items, then also the page postbacks and so the list box get populated again. This will loose the newly selected items and none of the newly selected items will be saved.
So what should i do in order not to loose the newly selected items when i click the "update" button.
Note:- I need to populate the listbox on postbacks also. So the population of that listbox on postbacks cannot be discarded.

I have a listbox (lb1).When multiple values are selected from the listbox ,only the first value is shown in the label.
label.text=lb1.SelectedItem.Text; This seems to be working for just single value.
How can I assign multiple values to the label?I tried using the foreach loop with the listitem but its not working.

How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.

I'm having trouble getting selected items in a listbox to be seen as selected. On my aspx page there's a listbox and a button:
[Code]....
But if I change my condition to Not selected, the string does build, with every item in the list. So the Sub is reached, the items and their text and values are seen, but user selection of items doesn't work. What am I missing?

This code will display the selected value from the listbox. E.g. if I sellect Item 1 I will get the following output: You have selected Item 1.
Label1.Text = "You have selected " + DropDownList1.SelectedValue + "<br />";
But if I don't select anything and click on Submit button, I will get: You have selected
What would I need to make it display "You have not selected anything. select at least 1 item."
UPDATE: I am using ASP.NET WebForms.

Values in multiselect dropdown not getting selected when Select All option is selected for a SSRS dropdown. There are multiple dropdowns on the page. We have one dropdown whose output is being used to populate the second dropdown using a stored procedure. When we check the Select All checkbox on the dropdown then ideally upon page refresh all the values should get selected in the dropdown, but in this case the page refreshes back to the blank dropdown, forcing the user to select the values again. The next dropdown too does not get populated. This makes it impossible to run the report for all the cases by using Select All. We ran the report on differnet database environments. My current location is Mumbai,India, the report worked fine when we ran it on a Bangalore,india database. This issue occurs when we try running it on a Chicago database server. I am using SSRS 2005, SQL2005.

I've got a list box that's populated by the user, I want to enter the selected items into an array, however I need both the indexes they have in the listbox as a whole, as well as their values.
For example, let's say that there is a listbox with 3 values and the user has selected just the first 2.
I would like to do a "for each" statement on only the selected items, so I would need their listbox indexes, the selected items indexes and their textual values.
I've tried multiple paths but all seem to just give me the textual representation of the selected item, but getting the correct indexes seems to be a problem for me.

I have a list box which is populated using a dictioanry. When I iterate throught the selected items using the following code, it always show only the first items as selected - even if the first item is not selected. Have you ever encountered this scenario? This problem occurs when I use dictionary for binding. On the other hand a generic list works fine.
private void PopulateListBox2()
{
List<string> subjectList = new List<string>();
subjectList.Add("Maths");
subjectList.Add("Science");
ListBox1.DataSource = subjectList;
ListBox1.DataBind();
}
Even it will work fine, if the values are unique. But in my scenario, the values are same; only key varies. The following works
private void PopulateListBox5()
{
Dictionary<string, string> resultDictionary = new Dictionary<string, string>();
resultDictionary.Add("Maths", "Lijo1");
resultDictionary.Add("Science", "Lijo2");
ListBox1.DataValueField = "Value";
ListBox1.DataTextField = "Key";
ListBox1.DataSource = resultDictionary;
ListBox1.DataBind();
}
The following code has the problem......................
