Web Forms :: Splitting Rows In Listbox
Jan 14, 2010
I am working with the listbox and binding the data to the listbox. My question is if i retrieve 20 rows in a listbox then how can i arrange 10 rows on each column (splitting 10 rows side by side or dividing). sample:
Exact Data in a Listbox Looking for something like this:
Listboxitem1 Listboxitem1 Listboxitem3
Listboxitem2 Listboxitem2 Listboxitem4
Listboxitem3
Listboxitem4
I have one more question. How can I display my data in a listbox as a treeview structure with a nodes. Or can i insert treeview inside listbox.

trying to support my listbox control in safari/chrome as it works in ie. there are instances when i want the control to be 1 row high, but i do not want it to render like a dropdownlist. so, i set .SelectionMode = ListSelectionMode.Multiple. This works in IE...I have a 1 row high listbox that does not render like a dropdownlist. Is it possible to render the same thing in safari or chrome? currently, if i set .Rows = 1, it renders 3 high in safari/chrome. if i don't set .SelectionMode = ListSelectionMode.Multiple then i see a dropdownlist.

In my continuing effort to build a search page that sends gridview rows with a textbox txtQty <> 0 to a listbox via a datatable, I've written the following:
[Code]....
The page runs, I'm able to input values into the textbox and when I press the Add to Quote button inside my gridview, nothing is populated inside my listbox. Am I correctly binding my datatable to my listobx?

First of all, I'm relatively new to asp.net (3.5) and all of its controls. What I'm trying to do is to split up a detailsview. I have a submission form containing quite a lot of fields that are supposed to be filled out by the user. In my design I have a tabstrip with headlines about the different sections of the form. For example:
Tab1: Personal Info
Tab2: Info about your car
Tab3: Contact info
I have tested to add a new "user" via a DetailsView and it works. But what I want to do is to split up the contents within the <Field> tags In the DetailsView In different div classes (using css and javascript to hide/show the right tab contents). But when I try to do this Visual Studio says that characters like <p> and others aren't allowed within the Field tags, which makes sense. Is there any control to use for these kinds of situations?

Like many organizations, our customer service department receives faxes and process them in many different ways. The faxes come in through a queue. The faxes are presented to the user through a windows interface.The user ties a customer number to the fax and is allowed to split the fax into several different pages if necessary. They then send these different pages to different people in the organization.Currently the windows application that process these faxes uses a product that use to be part of Windows called KODAK.
The hope is that the current windows tool could be converted into a web application that provides the same functionality that the windows application offers. a tool that could be utilized inside an ASP.Net web application that would allow the user to receive a fax and split it like KODAK does? This application needs to be built in-house because of the custom needs of our customers. Something imbedded in the ASP.Net application would work for us.

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 have a gridview that is being populated by an oracle DB. The gridview have 2 columns now one shows years and the other is a checkbox column. What is happening is my years column is very long and I wanted to know if I could split the column in half. I want say from 1970-1990 in the first column. The second column will have the checkboxes for the first. I want the third column to have 1991-present day and the fourth column to have the checkboxes for the third column. Can the grid view do this or is this something I have to do in oracle and have the gridview just display it?
ex.
1970 chk 1991 chk
1971 chk 1992 chk
1972 chk 1993 chk
1973 chk 1994 chk

I'm using C# and ASP.NET 3.5. Basically I'm retrieving a column of data from a dataset and putting this into a list like so:
List<String> dates = new List<String>();
foreach (DataRow rowMonth in myDS.Tables[0].Rows)
{
string ListedMonthYear = (string)rowMonth[0];
dates.Add(ListedMonthYear);
}
The returned values are:
Apr-10
Mar-10
Feb-10
Jan-10
Dec-09
Nov-09
Oct-09
I'm interested in splitting these values into two lists with the idea of performing operations on them in the future.
Apr | 2010
Mar | 2010
Feb | 2010
Jan | 2010
Dec | 2009
Nov | 2009
Oct | 2009
What is the best way to do so?
EDIT: rowMonth is just the datarow that includes all date related values - the month-year, the month beginning, month ending, month active or inactive. Basically I'm just trying to extract that first column month-year to do operations on and ignore the rest.

The following is an example of using session state, which i can handle with a single variable. But this example uses. well you can see it. Where I am stuck is splitting the string into the three variables. Also, I am not too sure about the ; vs. a comma delimiter that usually see. I think it is a pretty old example. Session("Stocks") = "MSFT; VRSN; GE" ' Get Stocks, split string, etc. Dim StockString StockString = Session("Stocks")

For applications that need to have fastly different view layers, and I would like to still use the idea of the controller. I would ideally like to but the controllers in a Class Lib. and then have only the Views in a MVC Web Application. Taking the model out in this way works well, but I can't find a nice way to split the views and controllers.

I am building an application using asp.net mvc, DI, IoC, TDD as a bit of a learning exercise.
For my data access I am using the repository pattern. Now I am looking at membership and how this can work with the repository pattern. I am currently using a Linq to Sql repository but don't want to be tied to SQL Server for membership.
Secondly, I am looking to split out membership into a number of services:
AuthenticationService - identify the user
AuthorizationService - what can they do
PersonalizationService - profile
The personalization service will be what really defines a "customer" in my application and each customer will have a unique id/username that ties back to the AuthenticationService - thus, allowing me to use the default ASP.NET Membership provider, roll my own or use something like Open ID.
Is this a good approach? I don't want to reinvent the wheel but would rather these important parts of my application follow the same patterns as the rest.

I'm using the commandArgument property of the LinkButton ( Which is wrapped inside a repeater ) to pass two values -as one string- to a second repeater then I try to split them into two values, So I could use them as parameters in my ADO.NET Code (SqlCommand Parameters)....after testing my queries don't return any results but If I passed fixed values for the parameter or change the source of the parameter (just for test from a textbox or querystring or something) I get my results, so I think the problem is in splitting.
I Conduct some arugment values from the ArgumentCommand property of the LinkButton -which is wrapped inside a repeater:
<ItemTemplate>
<asp:LinkButton id="sort_lnkbtn" Text='<%# Eval("value")%>'
CommandArgument='<%#string.Format("{0}|{1}",Eval("arrange_by_id"),Eval("value"))%>' runat="server">
</asp:LinkButton>
</ItemTemplate>
Then I receive these values and cut them into two pieces of information:
string sortByAndArrangeBy = (e.CommandArgument).ToString();
char[] separator = { '|' };
string[] sortByAndArrangeByArray = sortByAndArrangeBy.Split(separator);
Now the ado.net code uses this values as a
using (SqlConnection cn1 = new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString))
{
using (SqlCommand cm1 = new SqlCommand("SELECT [name] FROM brands WHERE (name like @SearchString + '%' )", cn1))
{
cm1.Parameters.Add("@SearchString", System.Data.SqlDbType.Char);
cm1.Parameters["@SearchString"].Value = sortByAndArrangeByArray[1];
cn1.Open();
using (SqlDataReader dr1 = cm1.ExecuteReader())
{
List_rpt.DataSource = dr1;
List_rpt.DataBind();
}
}
}

I have too many lines in my code behind file. Now it grows up to almost 3500 lines. I wonder if it can be splitted into several files.
To be specify, say I have CustomerEdit.aspx and code behind as CustomerEdit.aspx.cs. In my code behind, most of them are functions taking care of UI (i.e. protected void ... _Click() or protected void ... _SelectedIndexChanged()). I have some private functions, but they usually refer to some UI elements.
Question: Can I safely seperate CustomerEdit.aspx.cs into smaller files like CustomerEdit01.aspx.cs, CustomerEdit02.aspx.cs, etc?

I have a large string that I want to save in a cookie, however I don't know what the best practices are for max string length per cookie, and max cookie count. What logic should I use to split the string and later combine a set of cookies?
(Microsoft ADFS and perhaps Siteminder do this technique so I would be interested in what thier implementation is)

I currently have an ASP .NET MVC / EF4 project that contains many pieces of autonomous functionality such as a blogging, events, contests, wiki, etc.
The entities used by each system are all mapped to my database through one giant EDM file.
This works well for the main site, but I also have a few personal sites where I want to reuse just the blogging functionality from the mains ite.
My biggest problem is that due to the mac daddy EDM file, my blog sites have to constantly have their database schemas updated to reflect changes made to areas of functionality that they don't use (i.e. changes to the events system).
The only other gotcha is that there are some entities (Users and Tags) that have relationships with entities from each area of functionality, making it hard to simply split each area of functionality off into its own EDM.
With all of this said, I'm trying to figure out the most efficient way to set this up.
Should I go down the road of splitting up the EDMs by each area (blogs, events, contests, wiki) and figuring out a way to maintain relationships for the User and Tag entities?
Or should I just perhaps be creating an EDM for each website that only maps the entities that it will actually need? The only problem with this is that my repository layer takes in a UnitOfWork/ObjectContext, and by creating new ObjectContexts for each site I'd have problems reusing my repository code.

How would i go about searching for data in the profile system?
I am looking to make a page with a search bar - type in a name, and this goes to searchresults.aspx?id=what you just searched.
How then do I select the Profile.FirstName and Profile.LastName within the profiletable?
Because it is the auto generated profile system, these values are stored withing the Profile table but not as seperate columns..
Also, how do i split up the querystring into a first name and last name to match to the seperate profiles?

I am having an issue with a simple databind to a datagrid. What happens is that for some reason, the first character of the data going into the 4th column is getting placed at the end of the data in the third column; but only on the first row. Here is an example of what I mean:
Form ID
Employee No
Associate Name
Start Date
End Date
Form Status
1234
5000187
Stan Marsh1
1/16/2010
11/30/2010
Approved
1234
5000187
Eric Cartman

Approved
1234
5000187
Kyle Broflovski
11/16/2010
11/30/2010
Approved
As you can see, in the first row of data, a "1" has been moved from the Start Date column to the Associate Name column. Because this is a databind I don't see how this is even possible. I'm just curious if this is a known issue or just some random fluke. Here is the relevant code:

I am having problems with the .split function.
token_list = line.Split(',');
My input data is a CSV file that contains numbers and strings totaling 5 columns. The strings are string delimited...
1, 2, "Test", 1, "Test" 5 columns
1, 2, "Test", 1, "Test" 5 columns
1, 2, "Test, Test", 1, "Test" 6 columns!!
1, 2, "Test", 1, "Test" 5 columns
The split function as it is written above is splitting the third line into 6 columns because there is a comma in the data. Is there a way for me to tell the split function to ignore commas in strings?
