Web Forms :: Save ListBox Selected Items To Database
May 7, 2015
I have a DropDownList shows the company names and a ListBox shows the products of the company I selected in the DropDownList and I can select many products from ListBox:
in sql I have these tables:
1.company: comp_id,comp_name
2.product: prod_id,prod_name
3.Pro_Comp_details:Pro_Comp_ID,Pro_ID,Comp_ID (bridge table)
In .net I have a page with a button to add to bridge table to add a company and many products to it
this is my code but there is something missing
protected void btn_save_add_Click(object sender, EventArgs e) {
poc.Pro_Comp_ID = Convert.ToInt32(txt_prod_of_compID_add.Text);
int id1 = Convert.ToInt32(String.Format("select Comp_ID from Company where Comp_Name = '{0}'", ddl_choose_companyName.SelectedValue));
int[] id2 = new int[ListBox1.Items.Count];
[Code] ...

I am using a multi-select listbox to show a date. I want to process all selected values and store them in my database.
How do I process all the selected dates and save them in a database?
Is it possible to store all the selected dates in a single row?
Is there an alternative for storing the value?

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?

I 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 the following code which simply gets data from a table and populates the questions_lb listbox with items. I have a button on the page, which when clicked, should write (on submit) the selected state of each of the items. The code below writes the text values of each of the items fine however it always writes the li.Selected as False even though i have selected items from the list. Note that you can select Multiple items from the list. Does anyone have a clue why its not writing 'True' for an item that is selected on submit?

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......................

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 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.

What is the standard practice for updating your listbox or combobox selections to a database lookup table?
Suppose you have a list of groups that an employee can be a member of. The user selects one or more groups and hits the save button. What is the best practice for updating the database?
Should I first DELETE all groups assigned to that user, in case they exist, and then INSERT the selected ones?
Or should I go through each list item and if it's not selected, DELETE it. If it is selected, check to see if it exists first, if so do nothing, if it doesn't INSERT it?
Or is there a better way to reconcile selections with the database table?
