I have 5 hard corded texboxes in a page in a sequence with sequence Number . Now i want to add re-order /re-arraning functionaly .. but i can't use ajax reorder list because i have 5 hard corded texbox. how can i maintain the order in Insert/Update cases. And also suggest me control that i can use, another than ajax re-order list. coz i not using any list items i have hard corded items on the page.
View 1 RepliesThe AjaxToolkit has a ReorderList. I'm searching for a jQuery solution that does the same and found this page. I would like to change the order of divs (vertically) and upload the new order to the database (ajax).
View 2 RepliesI have two table Order and Order Detail.
What i need is i need to bind last 10 Order in Gridview/details view with paging, and the same order detail also fetch from database and shown in another gridview.. if user click any oderNo in first Gridview/DetailView then i need to show Respective order detail in anther gridview..
without postback coz we already fetch 10 order with orderdetails from the database..and if user click next 10 orderNo using paging then again we need to load 10 orderNo with respective orderdeatils from database like this going on....as well as let me know how to take print of particular oder and order detail....?
From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

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 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

I really have a big problem(stuck) with two dropdownlists inside a detailsview.I have 4 detailsview : DdlRt,DdlRt2,ddlMobv1,ddlMobv2. Basically what happens here is that DdlRt2 gets populated when DdlRt is selected and ddlMobv2 gets populated when a specific value from ddlMobv1 is selected.
In code posted above the detailsview has a "Update" command and the problem is when the update command is executed the data is successfully posted to the db BUT! THE VALUES from DdlRt2 and ddlMobv2 dissapear! And I can't insert any more Items. The only Item that stays in these two dropdownlists is the default "Select Department" item which is't set in codebehind but is set in .aspx.....I can't figure what I'm doing wrong here It must be something with databinding & events.
So my question is "Why can't I insert any more items to these two dropdownlists after the "Update" command on the DetailsView is set or how can I preserve the values that are already in"?
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataSourceID="odsRegister"

I have a multiline textbox whose .Text property get saved in an SQL 2008 DB. When I submit the textbox, I loose the returns. How do I handle this?
I've used Enviroment.Newline() to do some html conversion stuff, but I've never ran into this specific problem.
Edit: Nevermind, it was working just fine, but I was replacing " " incorrectly. Stupid mistake. I have to convert the " " to <p> tags. I've done this before, but if anybody wants to answer, I'll mark their answer as correct.
I have an ASP.NET application with 5 .ashx HTTPHandlers that implement RequiresSessionState or IReadOnlySessionState.Upon calling the first handler I create a variable and store it in the session.When I call the next HttpHandler the variable is not available in the session object.I am use context.Session.I have a global.asax where I retrieve the sessionId.Is there a way to preserve session variables across HttpHandlers or does each Handler get its own session?
View 1 RepliesI have the need to add a javascript include to my ASP.NET page. The url of the javascript file has two key/value pairs in the query string. But the ampersand is being escaped and I don't want that.
Page.ClientScript.RegisterClientScriptInclude("myKey",
"https://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2&s=1")
This results in the following HTML:
<script

I have an application with different sections. Each section is accessed through a domain. Example:
[URL] I need to preserve the session when the user navigates from one to another URL. The application is the same in IIS. How to accomplish that?
I am trying to figure out how to preserve the values of the controls on this page (just the user-submitted commission value and the sales region (eastern is 10% and western is 20%)).
The code is as follows:
<form id='frmShowCommSingleDocKeepState' action='afShowCommSingleDocKeepState.aspx' method='get' >
<div>
<%
Dim strSale As String
Dim dblSale As Double
Dim strRegion As String
Dim dblComm As Double
Dim E As Double = 0.1
Dim W As Double = 0.2........
I have a form, mostly consisting DDL's. I constructed this form using a Master page with about 10 different pages attached. Each page consists of roughly 10 to 20 DDL's. My goal now is to navigate from one page to the next and back with out loosing the selected values in each of my DDL's on each page. I have thought about assigning each to a Session but that would really bog things down considering the amount of Data i would be storing. I would love to go the easiest route but my mission here is most efficient.
View 12 RepliesOn the page load event of my webpage i fill the list of with the contents of the structure
Structure MainStruct
Dim Ans1 As String

The problem i that on post-back the contents of the list-of get lost.So, how can i preserve the contents of the list-of in ASP.NET?
I've written a user control that has a button that a user can click to display an additional DIV. I discovered that it would be nice to make the control remember whether or not the DIV is visible after postback so that when the page reloads, the DIV stays visible if the user wants it that way.
What is a good way to implement this with jQuery at my disposal?

I have a panel inside an update panel. The panel has a scrollbar. When a control inside the panel is clicked, the scrollbar resets, scrolling the panel back to the top.

View 5 RepliesI have a function that converts a .csv file to a datatable. One of the columns I am converting is is a field of names that have a comma in them i.e. "Doe, John" when converting the function treats this as 2 seperate fields because of the comma.
