I am trying to create a add all button to execute a query and insert all rows from a gridview.
Can't make it work, it only inserts one row.
vb Code:
Imports System.Data.SqlClient Public Class page1
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object,
ByVal e As System.EventArgs) Handles Me.Load End Sub

I'm trying to populate 1000 ListItems in a ListBox.
how to do it. Currently only 100 items are being displayed even though I set the capacity of the ListBox to 1000.
Below is sort of how my code looks like. :)
listBox.Items.Capacity = 1000;
foreach(entity ent in enitityCollection)
{
ListItem listItem = new ListItem();
listItem.Value = ent.Id.ToString();
listItem.Text = ent.Name;
listBox.Items.Add(listItem);
}
entityCollection has 989 records in it.
Code does not generate any error. only that at the end of the loop I only get 100 items mapped to my ListBox.
Is this how the ListBox is designed for?
Here is my code which insert listbox items table and create record.
protected void Button1_Click(object sender, EventArgs e)
{
ListItem li = new ListItem();
System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" + @"Data source= C:Ruchitaweb" + @"WebSite527afcergonomic.mdb";
conn.Open();
for (int i = 0; i < ListBox1.Items.Count; i++)
{
li.Text = ListBox1.Items[i].Text;
}
OleDbCommand cmd = new OleDbCommand("insert into record(recorditem) values('" + li.Text + "')", conn);
cmd.ExecuteNonQuery();
conn.Close();
}
this is inserting in diffrent rows but i want this in one row with (,)so i can parse it and get it back which items user selected. and i also want to show messge box that show the record number.

I have a dropdownlist, which dynamically populate data from SQL Server and i wanna manually insert two items on top of the DDL after data binding. So, the DDL would has data something like this:
Select Branch (manually insert)
ALL (manually insert)
AIR
AMP
ABG
...
I tried to achieve it by using code below:
ddlBranch.Items.Insert(0, "Select Branch")
ddlBranch.Items(0).Value = CMM.sExcVal1
ddlBranch.Items.Insert(1, "ALL")
ddlBranch.Items(1).Value = "ALL"
but it comes out giving me the data like this:
Select Branch (manually insert)
ALL (manually insert)
('AIR' branch should be here but it's gone)
AMP
ABG
...
After manually insert the 'ALL' item into the DDL, the 'AIR' is gone which is already replaced by the 'ALL'. How can i remain all the data from server and at the same time i can manually insert two items?
what I am trying to do is: insert multiple selected items from CheckBoxList into DB
I tried using (foreach) as:
foreach (ListItem item in bookingid.Items)
{
if (item.Selected == true)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString))
{
con.Open();
SqlCommand cmd2 = new SqlCommand("") }}}
But it only adds the first selected item .. What Should i do ?
i have added several items into a list box, but i m not sure how to insert the several items within the list box individually into the database..
for example,
- within my list box, i have apple, orange and banana.
- next, i would like to insert into database in different row -->
fruit name
apple
orange
banana

View 2 RepliesI have two ListBoxes. I can move items from one list box to the other. I have an Insertcommand for inserting added values from the "ActivePrograms" list box to a db.
my problem is that it inserts only one item when sometimes the user added multiple items.
how do I insert all existing items from "ActivePrograms" list box?:
second issue: how do I make sure the insert command go through the list of items in the listbox and makes sure these rows does mot already exsited in the db? in other words insert only NEW values for that 'Id' value

I have a DDL bound to a sqlDataSource, and I want to insert an item in the first position. I tried using this code in the onDatabound event:
Protected Sub ddl_onDataBound(ByVal sender As Object, ByVal e As EventArgs) Handles ddl.DataBound
ddl.Items.Insert(0, "None")
End Sub
But when I load the page, the item "None" is inserted twice at the beginning of the DDL? So I see something like:
None
None
item1
item2
Do I need to put the items.insert somewhere else, like on the pageLoad, to avoid it being executed twice, or am I doing something really wrong?

I have a settings page in my asp.net website,in which a user can select desired items and their order to be displayed in another page.I am displaying these items(which are obtained from database) in a gridview with checkboxes,up/down arrows next to them.Once the user makes his selection/rearranges the items and clicks on the 'Save' button,I am saving the data into another database table.When this particular user logsin again I want to check the items which were already chosen by him and arrange them in the order he specified, on page load.I am able to check the checkboxes of the already chosen items but do not understand how do I arrange the items in the user specified order?
Update: Basically 'items' in my question refers to column names of a database table.so once the user selects his desired column names and their order,the data corresponding to these columns gets displayed in another page in the column sequence specified.
