is it possible to select only the item that are displayed in the list box. That is i am having a list of item starting from 0 to 100 in the list box. But i have reduced the height of the list box so that it displayed the item one by one. I need the displayed item to automatically selected.
View 1 Repliesi want to show the arrayliust items in the listbox, for that i had stored some data in array list, and now i want that if i gv any id which is in the array list its corresponding details are displayed in listbox. I had two fields ID, Name, and when i give id its corresponding name should be shown in list box.
View 3 RepliesI have a listbox and used the sqldatasource to load the items in the listbox. But if there are no items in the result then i need to hide the listbox and show one msg like "no items". I know to check the listbox is empty or not using "Items.Count " , but which event will i check this?
View 2 Repliesi have a list box (listbox1) populated with some values.i also have a table with some values.I'd like to show values from table which are NOT IN listbox1.here's a code. I see what the problem is. Just can't understand what is the solution.If I have one value in listbox it works fine, but if more than 1 it messed up, since it tries loop several times.
[Code]....it works fine. The only thing: If I want to update some properties of item, but do not update name(just leave name the way it was) it still fires the validation, and my update cannot pass validation since this name is already exists.i have a listbox populated with values from linqdatasource (or from datacontext using code-behind) Also I have formview which allows to insert new values to database.When I insert new value in the database, this value doesn't show up in listbox until I recompile project/restart browser. When i refresh page nothing happen. Only old values are visible. Id like to have more dynamic page. I tried updatepanels. Maybe I need somehow refresh database connection first?
its possible to show multiple line text in listbox. For eg. I have two records as follows
#1
Pizaa 1 : BBQ Chicken
Add: Extra Sauce
Add: Extra Cheese
#2
Wings 1 : Hot Spicy
Add : Extra Red Pepper
Remove : Cheese
I have to provide "Remove functionality" , listbox is the easiest to provide remove functionality. I cannot modify above record format. If its not possible, then what is the alternate to overcome this issue.
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 ?

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();
}
The following code has the problem......................
I have a shooping cart in version 9.0.1.3
I have several products with two variants for each.
I can add any quanity to the first variant and it is calculated into the cart correctly.

I can change the quanity when it is in the cart. But I need it to work correctly.

I am designing a program that will let me enter the name of an item to swap and adds the swap to an array list when a button Add is pressed. Once the item is added to the array list a Sub Procedure should be called which displays the contents of the array list in a list box.
The system will also allow me to remove items from the array list using a Remove button
followed by updating array list.
I have done some part which puts item into the listbox1 which i named lstSwapList.I would need some assistance on the Sub Procedure to display the Value or Description on the other listbox2 which i have also named lstContent,if a value is selected from the listbox1.
I would also want to know how to update the Listbox content,However i hv added a sample of the way i guess it may be.
Any complete solution from anybody on the Sub Procedure and the Update Swap procedure will be greately appreciated.
The script below is what i have done so far.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged
End Sub
Protected Sub lstSwapList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstSwapList.SelectedIndexChanged
End Sub
Protected Sub btnAddSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddSwap.Click
Dim SwapValue As String = "Sixty Pounds"
Dim Counter As Integer = 8
Dim SwapN0 As Integer
lstSwapList.Items.Add(SwapValue)
lstSwapList.Items.Add(Counter)
lstSwapList.Items.Add(New ListItem("300", "1"))
lstSwapList.Items.Add(New ListItem("ASP.Net", "2"))
lstSwapList.Items.Add(New ListItem("Programming", "3"))
SwapN0 = lstSwapList.SelectedValue
For Counter = 0 To -1
SwapN0 = lstContent.Items.Count
Next
End Sub
Protected Sub btnDeleteSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDeleteSwap.Click
lstSwapList.Items.Remove(lstSwapList.SelectedValue)
End Sub
Protected Sub btnUpdateSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateSwap.Click
End Sub
End Class
=======================================
Sub UpdateSwap(ByVal valueA As String, ByVal ValueBAs String, ByVal ValueC As Integer, ByVal ValueD As Date)
I have two list boxes, one has a list of available users (about 1500 items) and the other is blank. There is a button to add the seleted items from the first list box to the second one. Both of these listboxes are within an update panel and for some reason it takes over 20 seconds for the items to show up in the second listbox.
Is this normal? Is there an alternate, faster way of doing this?
I posted a question earlier about updating the quantity column in my table, I use the code found below however I think because the Select and Update is inside of a foreach loop it is updating all of the products.
Furthermore, the products are also updated when the page is reloaded and the amount is increased based on how many times the user clicks on the add button. E.g. Click the add button twice the quantity increments by two each time.
I ideally need to be able to use the ItemID outside of the foreach loop, but can't.
Code:
foreach (UserItem ItemID in (List<UserItem>)Session["UserSession"])
{
ConclusionPage.InsertCommand = "IF EXISTS (SELECT ItemID FROM tblUserItems WHERE UserID='@CurrentUser' AND ItemID='@ItemID') UPDATE tblUserItems SET Quantity = Quantity+1 WHERE (UserID = '@CurrentUser') AND (ItemID = '@ItemID')";
ConclusionPage.Insert();
}
Perhaps someone has done something like this before. I am generating a quantity summary report. The quantities have to be summarized in two ways:A quantity for a specified date range, which can fall anywhere within the project duration defined by the user provided UserStartDate and UserEndDate A Quantity to date, defined by the ProjectStartDate till the user defined UserEndDate So if I put all these dates in sequence it would look something like this: ProjectStartDate, UserStartDate, UserEndDate, ProjectEndDate Right now in the code the User specified dates are vStartDate and vEndDate. The source data (list of bid items) is compiled in a UNION query (SqlServer View) and I am querying from this view using a stored procedure from which the data is captured using the code below.
Public Shared Function GETeFieldQuantityData( _
ByVal vProjectNo As String, _
ByVal vStartDate As DateTime, _
ByVal vEndDate As DateTime) _
As IEnumerable
' Dim SqlConnection, SqlCommand, and SqlDataReader
Dim vSqlConn As SqlConnection = New SqlConnection(GetConnString)
Dim vSqlCmd As SqlCommand = New SqlCommand("eFieldReturnQuantitySummary", vSqlConn)
'Dim vDataRdr As SqlDataReader
vSqlConn.Open()
'Construct parameters
vSqlCmd.Parameters.AddWithValue("@StartDate", vStartDate)
vSqlCmd.Parameters.AddWithValue("@EndDate", vEndDate)
vSqlCmd.Parameters.AddWithValue("@ProjectNum", vProjectNo)
vSqlCmd.CommandType = CommandType.StoredProcedure
'Return SqlDataReader Object
Return vSqlCmd.ExecuteReader(CommandBehavior.CloseConnection)
End Function
And the SELECT statement returning data to the form:
Code:
SELECT BidItemDesc As [Bid Item Description], Unit,
SUM(Qty) AS [Tot Qty], COUNT(*) AS Records
FROM dbo.qryQuantityWorkSheet
WHERE ((ProjectNum = @ProjectNum)
AND (ProjDate >= @StartDate)
AND (ProjDate <= @EndDate) )
GROUP BY ProjectNum, BidItemDesc, Unit
ORDER BY BidItemDesc
In crystal report, for data showing at below:
QUANTITY----PAID_DAY
12------------2/2/2010
35------------
63------------5/15/2010
13------------
How to add code to sum of Quantity if there is a day in [PAID_DAY]?
The result showing on the report should be 12+63=75.
I have 3 tables. Blog and Tag have a many to many relationship. BlogTag is a junction table with a quantity column.

We have a demand system where customer can demand the quantity they want for a particular deal.
For each demand they submit, a new record is added to the DealDemandRequest table with the CustomerID, DealID, Quantity
I want to be able to to calculate the total quantity demanded by a particular customer. Current I query the DealDemandRequest table for all the records by a particular customer and then do a sum of the Quanity column.
However, we are expecting this table to be over 1 million record and it is reallly really slow right now.. Any better ways?
