C# - Putting Tooltips Programmatically On ListBox Class?
Mar 15, 2011
I have created an asp:listbox and in the cs file, I am trying to bind it to a datasource. However, I want to put in tooltips for each option so that when you hover over a multiple-listbox you will see the name of the item in both the listbox and the tooltip.The following code is what I have tried (which obviously will not work), which will just put a big tooltip for the "select" html tag, instead of the "option" tags individually.I think I need a loop, but I'm not sure how to add attributes to each element and the ASP documentation is no help. I bet it's an easy solution, but I can't figure out how to do it.
I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.
I have a function in a code behind file that's used to respond to a gridview event:
protected void GridviewEval(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { foreach (TableCell cell in e.Row.Cells) { if (cell.Text == "0") { cell.Text = "-"; } } } } It's currently in the code behind of a page and I'll be using it in other other pages.I would like to use the same code in other pages.When I cut and paste the function into a class,it's not working.
I'm trying to set up a smart way to handle email in my ASP.NET Web Application Project. I created a class in my App_Code folder named "MailHelper.cs" but am having trouble invoking it in the code-behind pages. Can someone please correct me on the correct way to do this?Here's the Mail.Helper.cs file in App_Code:
[Code]....
How do I invoke this when I'm ready to fire off a message? Let's say I have a Submit_Click event and want an email to be generated:
I need to populate a listbox programmatically from 1 of 2 tables, depending upon user inputs at run time and I need to know how many rows to read. Otherwise, I get an exception error when I try to read data that does not exist after all rows have been read.
In my project asp.net (c#), I am using threading to process some messages. I have a display page that contain a listbox with all the actions that are taken in processing the message. And a class where I am processing the message.
Default.aspx:
protected void Page_Load(object sender, EventArgs e) { //starts the thread and call the method from Process.cs }
[Code]....
But the listbox do not show nothing. Does anyone has any ideea where I'm wrong?
I am writing an application that does it's own logging in a SQL table. On each page, I statically assign this variable: Dim page = "page_01.aspx" I've noticed that page is ALWAYS equal to the name of the Partial Class of the code-behind + the suffix ".aspx" Is there any way to programatically set the string to equal the name of the Partial Class, so I don't have to statically code it on each page? Basically, I want to assign the name of the current class to a string, and append ".aspx" to it. Can I do this, or does that get lost in the compilation?
then I would like to set the class for the li according to the controller value. How do I do that?
Something like: if controller == "home", then set the class for the li with the home id to active.
I just started learning MVC and am very new to the syntax. when you respond to this posting provide syntax, as I am coming from code behind background.
I looked into a nice way to display tooltips dynamically and I found OverLibWrapper, which was exactly what I needed.
I have all the tooltip data stored in a custom configuration section, the tooltips are bound to their respective controls during Page_Load.
I did a quick test and worked fine. The problem came up when I realized that OverLibWrapper didn't work on masterpages. Our website has uses quite a few masterpages, so taking them out isn't an option.
I was wondering if there's anything like OverLibWrapper that I could use.
EDIT:
What I'm looking for is a control to display good-looking tooltips on mouseover preferably instantly like overlib (nothing fancy because I'm just displaying raw text) in a dynamic way, because the tooltip property in ASP.NET is not very pretty and takes a while to appear. For example let's say I have a collection of Messages:
class Message { string ctrlid, msgtodisplay; }
And when the page is loaded:
TooltipManager manager; foreach(var m in messages) { Tooltip tltp=new Tooltip; m.ControlID=m.ctrlid; m.Message=m.msgtodisplay; manager.AddTooltip(tltp); }
So basically something that offers the functionality of Tooltip and TooltipManager.
If TypeOf (e.Row) Is GridView.GridViewHeaderRow Then Dim row As GridView.GridViewHeaderRow = e.RowFor Each cell As GridView.GridViewHeaderCell In row.CellsDim texts()
I have googled this and tried soo many examples online but none of the example does that i really want. THis is basically what i want I have a gridview of the following form below ID PLACE A)BOSTON B)NEWYORK.now, I would like a situation similar to this where basically once the mouse is moved over A or B, it should show the header which is ID. No javascript please.
I am using Ajax CalendarExtender , the calendar work well. I want to hilight and tooltips holiday that I define on calendar. I found some similar post , but failed to work. Below is my code.
I am using a treeview in a web part that I am writing. When the user moves the mouse over the +/- icon in the tree, a tooltip is shown: "Expand FolderName" or "Collapse FolderName". Because there is a requirement to localize this web part, I need to be able to set a localized tooltip, replacing the english one. (That english string appears, even when the machine is running a Chinese OS.)how to accomplish this localization?
I'm new to ASP.NET (both the site and the platform) and am I wondered if you guys could help me figure out how to add tooltips to a DataGrid column, specifically, the HyperLinkColumn (example shown below). I'm sure there's some magical way to do this in JavaScript but a search turned up nothing.
I am trying to add a tooltip to each AxisX label on a Stacked Bar Chart. It displays the same value all the way across. Below is the code With.ToolTip =
Chart1.ChartAreas("ChartArea1").AxisX"Month = #VALX" .Interval = 1End With
I have been asked to display tooltips instead of plain text when form validation fails. We are currently using asp.net MVC 3 data annotation validators to display validation error messages. I am still fairly new to MVC and I have spent hours online looking for a clean solution
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

I'm trying to auto-populate a listbox of zip codes from a database table state_zipcode_plans based on the state a user selects from the previous listbox. I'm getting the error: Must declare the scalar variable @state_code.
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?
how I can read the selected field from the listbox?I have MSAccess table attached to the app.I can get to the properties, but I don't know which property gets me the data of the specific field.In VB it would be "listbox1.Column(x)", where 'x' represents the column number in the listbox1.I am using Microsoft Visual Web Developer 2010 Express
