Asp.net - Keep Selected ListItem From Ignoring Other ListItems?
Aug 16, 2011
When I run code the below, the If statement never resolves to 'True'. It always shows 'Assm' as the SelectedItem, even if I check all the checkboxes. So how do I allow 'Assm' to be checked by default AND have the code-behind see that the other checkboxes are checked?
I'm selecting a ListItem as I add it to a ListItemCollection. Then I use that ListItemCollection as a datasource for a DropDownlist but the Selected List Item is not being selected after databind.[code]...

I'm trying to get this to work so I can return only a list of items, instead of a list of items and the selected value. Is there a way to make the DropDownList select the selected ListItem from the ListItemCollection (or any other type of collection)?
i have a combobox with autocomplete to listitems it works very fine if i wrote the first letter it suggests a list of items that starts with this letter. i need to make it work if i write any part of the word not only the first letter?
I have filled my listview with items, most of which have different backcolors, now this worked fine with .Net 1.1 with VS 2003 but now I have "upgraded" to VS 2005 and .Net 2.0 they are no longer being drawn with there backcolor at run time (both in debug and release)...However, I have a function that will export any listview into excel and this keeps the column widths, row colours and row fonts all in tact, and low and behold the colours are correct in excel, so why are the colours not being draw on the control?
Oh, and I have just noticed.... Literally while writing this post, if I resize the window (which forces the listview to change its column widths to stay looking correct) in a "vertical" direction it draws the colours on and off..... this is a very strange bug, it also draws the colurs if I min the window and open it again.......So I recap... when I load up the listview the colours are not drawn, if I resize the window so that the control grows in height the colours flash on and off, and if I min the window and open it again the colours are there...
I have a DGV bound to a bindingsource with a column that uses a DataGridViewCombobox, that has a DataTable for it's datasource. This all worked fine at first.But I removed a row from the DataTable that the DGV combobox uses as its datasource. Now when I try to load the form that contain the DGV, I get an error "DataGridViewComboboxCell value is not valid" for each row that contains the value I removed from the DataTable.It seems the value of the column must be a member of the combobox Listitems. Is there a way to allow values not in the combobox ListItems. I don't want the combobox listitems to be locked in for the life of the application.
I'm new to WPF and databinding. I need to bind expander header to a List(Of Names) and expander content to a List(Of Services). I'm even more confused after reading MS tutorials on databindings (how and where to use staticResource, Path, etc.)

How do I bind header textblock to the person name and the inner listbox item to their services ?
I have a page that contains some dynamically created controls (TextBox and DropDownList). When a postback occurs, the TextBoxes keep their values, but the DropDownLists lose their ListItems. This is quite confusing, since the page level DropDownList also keeps its ListItems.
<%@ Page Language="VB"%> <script runat="server"> Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)
The text renders as literal <b>My Name</b> instead of making the text bold. The same thing happens if I try to add a list item from the VB side of things:
Dim li As ListItem = New ListItem("<b>My Name</b>") Me.listClientContacts.Items.Add(li)
Is there a way to add HTML to a ListItem in ASP, or is there a better way to dynamically generate a list?
When the user selects a name in the listbox and clicks a button I save the name in a var called "parent".What I want to do is programmatically move the selected name to the top of the list and take that whole list and drop it in a dropdown. I started the code below but don't know how to move the selected list item (parent) to the top of the list??
Private Sub GoLower(ByVal parent As String, ByVal lst As ListBox, ByVal ddl As DropDownList)
I would like to add to my RadioButtonList a ListItem displaying a DatePicker on select. How do I go about adding this in code please, I mean the DatePicker? The code below is my attempt at this but does not work
Dim datepick As New DatePicker With datepick .ID = "RadDatePicker1" .MinDate = New DateTime(CLng("2006-01-01")) .SharedCalendarID = "sharedCalendar" .Width = New Unit(100) End With RBtnList.Items.Add(New ListItem(datepick, "Other"))
i have a dropdownlist that populates from the sql server database. populating the list is not a problem, but does anyone know how to populate the value part of the listitem.
I am confused with the removing multiple selection from listbox ...been searching over internet .. but still I do not get the right approach or simply say it doesn't work. I tried to loop through the list without removing any of the item from listbox. I printed the item.selected and it showed that only the first one I selected printed true, others were not ...
I am trying to get the bound values from a row in a ListItem. I have a button on each row that when clicked will perform a task (sending an email message to the person who's name and email address is in that listitem row. So, I have an event handler tied to the listview, and I am trying to get to the underlying datarowview to extract the data items.Here's what I have in the event handler:
Protected Sub lvUsers_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewCommandEventArgs) Handles lvUsers.ItemCommand Dim diCurrentUser As ListViewDataItem = CType(e.Item, ListViewDataItem)[code]...
Now, it fails at the line where I am trying to access the contact_email element in the DataRowView object.What an I doing wrong?
I have a drop-down asp:listitem box that looks perfectly clean to me. It functions like when the first time you change a language on that page (Say, English to Swedish), it does change the text to that language.
The second time you try to change the language (Swedish back to English -- or any lang), it just reloads the page and then you have to select English a second time to actually change the page back to English.
I tried removing lines from the code behind, one at a time, but nothing changed it.
I am trying to create a single listitem that has multiple lines. When I create a newline using "System.Environment.NewLine" I get an empty box rather than the text going down the next line.
How can I get this to work? Currently my listitem is a custom structure. Do I need to change anything here so I can have multiple lines? Perhaps its a limitation of the listbox?
Public Structure ListItem Private displayText As String Private itemValue As Integer
The application that I am working on is a Service Desk App. I have a form there that uses a DropDownList that contains employees names coming from the Active Directory. Any employee can make a request and save it. Problem arises when an employee leaves the company and consequently his account is deleted from the Active Directory. When some other employee searches the DB to finds a relevant Service Ticket that could be of his use, when tries to open it an error is thrown that indicates that the name does not exist in the DropDownList items.
UPDATE:I am adding some code so that it can be more clear.
I am generating ListItems for a CheckBoxList control in ASP, but when I do something like the following:
... Dim newListItem As ListItem = New ListItem("RoleName") newListItem.Attributes.Add("style", "color:blue;") CheckBoxListControlToFill.Items.Add(newListItem) ...
"RoleName" is maintained from post back to post back, but my style tag is dropped after the first post back. If I want to keep any attribute like this, do I need to re-add it every post back?
I've got a problem with a program that references a third party ActiveX component that I've been refused permission to distribute. The AX component is used on some user defined controls which the user can add programatically, which makes isolating them fairly easy. However, the problem is that if the program is installed on a machine without the third party component then it just crashes, where I would much prefer it to just alert the user to the missing component and then disable the functionality that requires the component.
In the past I've tried adding the reference programatically but have found that this solution doesn't work with this particular control.
I'm writing a solution in VB.NET that consists of a number of different components (UI manager, Outlook add-in, etc.). In the main UI program I'm serializing out an arraylist to a data file that contains the data the other components will need to do their jobs. That part works fine, and I can serialize and deserialize with no problem. Now I want to read (deserialize ) in the data in my Outlook add-in, and I ran into the dreaded 'Unable to find assembly' issue where it's looking for the original assembly that serialized the data. I found a hint for workaround
Because there is so little information about VB.Net and (Fluent) NHibernate to be found, I decided to write this question to all other developers finding themselves looking for more information.On of the things i had to struggle with was how to Ignore properties in NHibernate.The reason i had to ignore properties was because we used a Webserivce which cannot serialize Interface classes (ILists). Which are used a lot with NHibernate.
I'd like to know if anyone has a code for or can direct me on how to select keywords given in a speech command and to ignore the other words. Example: Speech "The beach looks great today"
I want to use the word "beach" to trigger a function and ignore the rest of the speech.
I have a Powershell script and no matter what I try it completly ignores any quotation marks in the script. The error occurs when I run the script from my VB.NET code yet, I have been running scripts sucessfully through VB.NET for a while now. For example, my script starts with finding out the server name...
I have only started programming in VB recently and I am not very good on the coding side. I have two values a and b. When I divide them, I want only the integer part to show up ignoring all the decimals and storing it into the variable c.
