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?

View 3 RepliesI 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();
}

View 9 RepliesI have two databound listboxes. The first only shows items that have been assigned to my product. The second listbox shows all available items. What I want to do is select all of the items in listbox 2 that list box one contains.

ListBox1-
Item 1
Item 3
ListBox2-
Item 1 (Selected)
Item 2
Item 3 (Selected)
Code I have:
List<string> myList = new List<string>();
foreach(ListItem f in ListBoxSourceDetail.Items)

myList.Add(f.Value);

myList.ForEach(delegate(string n)
{
ListBoxSourceEdit.SelectedValue = n;
});

I am persisting the search selection criteria of a listbox onto another page which is called AreasLb. Multiple areas can be selected, I simply want to set the listbox items that the user selected as .Selected = true
I think the below code should work, but it doesn't, with no items in the Listbox being selected.
if (s == "Areas")
{
string[] area = nv[s].Substring(0, (nv[s].Length - 1)).Split(';');
int i = 0;
foreach (ListItem item in AreasLb.Items)
{
foreach (var s1 in area)
{
if (s1 == item.Value)
{
AreasLb.Items[i].Selected = true;
}
continue;
}
i = i + 1;
}
continue;
}

I'm trying to use the ListBox html helper in a simple form.
verhuurPrijzenLst is a simple list that gets put into the ListBox, I think I need "MultiSelectList", but I cannot use it (MVC framework needed)?
I don't know exactly how to do that ( bin folder and @inherits ? )
So it's nice to have a helper at hand, but if you cannot use it properly without using the MVC framework, that is a pity.

I have listbox where I am binding values from my database. Now my requirement is when user select values from listbox he/she can select only 4 values from listbox. If user select less than 4 or more than 4 values. I need to show validator that you can select only 4 values. How to achieve this?
View 1 RepliesI had used listbox control with multiple selection mode. I stored id with comma delimiter in database.
e.g.
1. List Item One.
2. List Item Two.
3. List Item Three.
4. List Item Four.
5. List Item Five.
6. List Item Six.
Suppose user select item 2, 4 & 6. So I will store it as a 2,4,6 in database. This will work fine.
Now in editing I have to shows selection-bar for item 2, item 4 & item 6. So I had typed below source.
string strData ="2,4,6"
if(strData != null)
{
char[] separator = new char[] { ',' };
string[] strSplitArr = strData.Split(separator);
int x = 0;
for (x = 0; x < strSplitArr.Length; x++)
{
// lstWDef_PurchasesEdit.Items[x].Selected = true;
lstWDef_PurchasesEdit.SelectedValue = strSplitArr[x].ToString();
}
}
But with this statement I got only last item id as a selected item with selectionbar. In our example 2,4,6 only item whoseid is 5 got as a selected item.
if i use
for (x = 0; x < strSplitArr.Length; x++)
{
if (lstWDef_PurchasesEdit.Items[x].Value == strSplitArr[x])
{
lstWDef_PurchasesEdit.Items[x].Selected = true;
}
}
if the selected items are serial like 2,3,4 then it is displaying correctly..
if items are 2,4,6 then it is not selecting the items of listbox properly.
Is anybody guide me how to make item 2, item 4, item 5 as a selected item ?
i have asked myself if there is an easy way to check if a ListBox has a maximum of 5 selected items. There must be at least one and at most 5 items selected.Do i need a CustomValidator with server-side validation?

I added some food items in CHeckBoxList. I want to add selected food item(s) in a ListBox. The Text Property is name of the food and it's value is there Price (Food Price) As soon as I add any food item in a ListBox the total should be displayed.
Whichever code I wrote using it, if i select 1 item then it adds in a ListBox. But If I select another food item then Previous food item also added because it is selected. I will select some food items then it will be adding in the ListBox, I will check the total, if the total is greater than my budget then i can remove some food items.
