C# - Refresh A Webpage Automatically From Within A Loop?

Feb 28, 2010

I have a loop that runs through a variety of websites and I'd like to put some kind of a postback in the loop so that each time through a textbox would refresh with the url that is currently being considered. I don't know AJAX yet so I'd like to redo the webpage. I am currently using a session variable to hold data for display between page loads. I have tried

1) Response.Redirect("Default.aspx");
2) Server.Transfer("Default.aspx");
3) Page_Load(sender, e);
4) this.RaisePostBackEvent(URLTextBox.Text);

but they don't work, possibly because I am not implementing them properly. I'd like to watch the current situation as it is updated within the loop.

If I make a change to my database (let's say I add a column to a table), is there any magical buttons that I can click to have my Linq to SQL model update to reflect the changes to my table?

Forms Data Controls :: ListBox, Array List / Update The Listbox Content?

Mar 26, 2011

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.

&#65279;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)

Web Forms :: Adding Item To Listbox From Another Listbox Taking Way Too Long?

Mar 4, 2010

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?

Refresh A Listbox In One Form From A Second Form?

Sep 30, 2010

this should be pretty simple but I can't find a solution. I spent a bunch of time, without luck, searching for an answer that makes sense (to me).
Here is the problem. I have an asp form in a frame (I know frames are considered evil, but this part is non-negotiable) This form has an asp:listbox that is tied to a SqlDataSource. A button on this form opens a second form that allows the user to add records to the SQL table that is bound to the SqlDataSource object (the source of the listbox in the first form) The thing is, that when the user closes the second form and returns to the first, the list box needs to be refreshed and I have no idea how to do that.
