I get a list like this
List<Territory> lst = new List<Territory>(); //it is from a class file.
How do i apply to a listbox in the .net form?
I was trying like this and i get error.
DropDownList1.DataSource = lst1;
DropDownList1.DataTextField = "Description";
DropDownList1.DataValueField = "ID";
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 a drop down that lists all our 40+ locations.. I then have a list box with all our locations as well. The client is presented with the question which locations have you worked at before. If they pick say 3 locations, i need to remove or disable those 3 from the drop down. I have other code for creating a drop down, but not sure where to go with this.
Here is my code for the controls and code behind:
[Code]....
<a href='<%# VirtualPathUtility.ToAbsolute("~/ProductsList.aspx?CategoryId=" + Eval("CategoryID")) %>'><%# Eval("CategoryName") %></a>
it bring me this error Conversion from string "~/Products.aspx?CategoryId=" to type 'Double' is not valid.

I have to remove the list of selected items from listbox .
Dim i As Integer
For i = 0 To listbox1.Items.Count - 1
listbox1.Items.Remove(listbox1.SelectedValue.ToString())
Next
My doubt is If i run the page again the listbox shows the items which i deleted already.
I have one Listbox and a List of data
I want to bind the list to listbox.
I have built one of those 2 listbox things where the items in the left textbox can be selected and moved to the right list box. The items in the list can be thought of as tasks (like Raise Invoice, Call Client, Deliver goods etc) The rules of this are that the item you move to the right box remains in the left box. Reason being, you are allowed to add the same item from the left to right as many times as you like. An example what the list on the right might look like is this.
Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal
Now I have added the feature to select an item on the right and hit the UP button, to move it up in the list. For example I could select 'Deliver Goods' and hit the up button. (the down button works as expected)
Raise Invoice
Deliver Goods
Call Client
Installation
Call Client
Finalize Deal
If i select the 2nd instance of Call Client and hit the up button,
Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal
This is what happens.
Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal
My code that loops though and does the move relies on the item.selected property to find which on I have selected. (obviously)
[Code]....
Despite having the items at the bottom of the list selected, the .Selected property is true on the first instance of the item that happens to have the same .Text and .Value.

View 1 RepliesI am having 3 ListBoxs(LB1,LB2,LB3).In LB1 I am binding the names of Courses through database.The code is shon below...
da1 = new SqlDataAdapter("SELECT COURSE_ID,COURSE_NAME FROM Course_Mst", con);
DataTable dt1 = new DataTable();
da1.Fill(dt1);
lstCourse.DataSource = dt1;
lstCourse.DataValueField = "COURSE_ID";
lstCourse.DataTextField = "COURSE_NAME";
lstCourse.DataBind();
Whenever I select particular course in LB1 all the content related to that course will be binded in LB2.The code is shown below.....
protected void LB1_SelectedIndexChanged(object sender, EventArgs e)
{
da2 = new SqlDataAdapter("SELECT SPEC_ID,SPEC_NAME FROM SPEC_TRANS WHERE COURSE_ID="+Convert.ToInt32(lstCourse.SelectedValue)+"", con);
DataTable dt = new DataTable();
da2.Fill(dt);
lstSpecilization.DataSource = dt;
lstSpecilization.DataValueField = "SPEC_ID";
lstSpecilization.DataTextField = "SPEC_NAME";
lstSpecilization.DataBind();
lstSpecilization.Focus();
}
I am having a ADD button.In LB2 I can select multiple items.When I select multiple items in LB2 and click on ADD all the selected items will be binded into LB3.The code is shown below...
protected void btnAddCourseDetaisl_Click(object sender, EventArgs e)
{
for (int intLoopIndex = 0; intLoopIndex <lstSpecilization.Items.Count ; intLoopIndex++)
{
if (lstSpecilization.Items[intLoopIndex].Selected)
{
ListItem li = new ListItem(lstSpecilization.Items[intLoopIndex].Text, lstSpecilization.Items[intLoopIndex].Value);
LB3.Items.Add(li);
}
}
}
My problem is when I select a item from LB2 and click on ADD the selecteditem is added to LB3 but if I select the same item and click on ADD the items are again added to the LB3.I want to prevent this.Pls respond me ASAP.
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 m displaying all errors in a Listbox. and I set the listbox size as the listbox count that means..no of errors. It is very good but the problem. is if the error is one, it is displaying and giving dropdown at the end. I dont want that dropdown.

I have just recently converted my VB code to C# and now having this error when I try to add an item to my listbox, and the value is coming from the item page. I get the error at this segement:

Here's what I have so far:

My guess is that the source of the problem could be in the foreach loop from my cart class, shouldn't I be using that for arrays only? If I need to post any markup code or any other class, let me know.
I have a Detailsview working fine in ASP.NET 2.0 VB. where I can obtain any links or articles detailing the settings for the Template as a guide to me apply RegularExpressionValidators to a number of the fields in my application.
My application works fine with the Required Field Validator. The majority of examples that I have been able to find are using this particular Validator.
I have a page on this page I have multiple user control and one of the control is on the user control.
on a button click event I can check all the validatoin which are on the main page, but I can't apply the validation on the user control which is not on focus. On the button click even if that particualar tab is on focus , the validaiton works otherwise it just ignores it.
I have a dropdown list in my webform and want to make that dropdown required in one form and optional in another form based on some conditions. My mark up for that is

<asp:DropDownList
ID="ddlMortgageInsWaiver"

I have a RadioButtonList control, containing two ListItems. These two Radio Buttons toggle each other, so that only one is selected at a time. When the second is selected, it affects whether a Textbox is enabled or not, and also erases the text in the Textbox when selected. Lastly, a Button is present to execute the selections made.
I have a RequiredFieldValidator and a RegularExpressionValidator on the Textbox, since when the first Radio Button is selected, I need to validate the entry. However, I need to turn off the functionality of the Validator controls when the second Radio Button is selected.
I want to apply custom css to my calendar control. i have applied the same at corresponding locations for e.g.
e.Cell.CssClass = "highlight";
clndrEvt.TodayDayStyle.CssClass = "currentDay";
clndrEvt.OtherMonthDayStyle.CssClass = "OOB";
clndrEvt.NextPrevStyle.CssClass = "dayTitle";
However when i render the control, my styles are not reflected.
When i check 'View Source' it applies my classes(italic) and ALSO applies in-line styles (underlined)along with it, which overwrites my styles. for e.g.
"class ="highlight" align ="center"
style ="color:White;background-color:Silver;width:14%".
how to remove those in-line styles (by using which properties) from the html by settings properties of calendar control.
I have tried few, but that did not work.
e.Cell.Attributes.CssStyle.Clear();
e.Cell.Attributes.Add("Style", string.Empty);
clndrEvt.Style.Clear(); {clndrEvt is my calendar control}
