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] ...

Web Forms :: Selected Items In Listbox To Be Seen As Selected

May 17, 2010

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?

Web Forms :: How To Show Multiple Selected Items Of A Listbox

Jun 18, 2010

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 ?

Web Forms :: Dynamically Populated Listbox Always Return Selected Items As False?

Mar 10, 2011

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?

Listbox - Show Only The First Items As Selected

May 1, 2010

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

C# - Listbox Persisting Multiple Selected Items?

Jul 29, 2010

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;
}

Web Forms :: ListBox Save To Database?

Feb 2, 2010

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?
