I have a requirement where a user logs on to a server where exists a website. The user bring up the site on a browser on that server and loads a power point presentation slide. At that time, users using their laptop clicks on the link to that site and sees that particular PPT slide loaded on the server. Then the operator/user on the server clicks on the second slide and the laptop would now see the second slide. Is this possible to do? If yes, then what technology to use? DHTML? or something else.

I am trying to use the TabContainer/TabPanel controls to create 3 tabs. The tabs themselves will always appear, however, only the first tab will ever display. When I look at the source of the page, I find that the 2nd and 3rd panels have style="visibility:hidden;display:none" on them. The only time this is not true, is if the content inside the tables is text that is on the source, nothing generated.
I have tried it using controls, repeaters, adding all my tabs dynamically, setting the properties of visibility=True and enabled=true. I am kind of pulling my hair out here.
ASPX coding:
<asp:TabContainer ID="aeDetails" runat="server">
<asp:TabPanel ID="placeholder" runat ="server" HeaderText ="PlaceHolder" ><ContentTemplate >Place Holder</ContentTemplate></asp:TabPanel>
</asp:TabContainer>
VB.NET Code:
' Get the content for the home page.
getHomePageContent()
' get the announcements, if any
getAnnouncements()
' get the events, if any
getEvents()
' remove placeholder after adding all three tabs
For i As Integer = 0 To aeDetails.Tabs.Count - 1
If aeDetails.Tabs(i).HeaderText = "PlaceHolder" Then
aeDetails.Tabs.RemoveAt(i)
Exit For
End If
Next
I will only put the code for one tab in here as they are all pretty much the same.
Private Sub getAnnouncements()
Dim nt As TabPanel = New TabPanel()
nt.HeaderText = "Viscardi Announcements"
nt.ID = "tpAnnouncements"
nt.Visible = True
nt.Enabled = True
Dim nl As Label = New Label()
Dim sb As StringBuilder = New StringBuilder()
Dim anRec As HVS_Announcements_Record = New HVS_Announcements_Record
Dim anList As List(Of HVS_Announcements_Record) = getCurrentAnnouncments()
Select Case anList.Count < 1
Case True
nl.Text = "There are currently no announcments for the Henry Viscardi School"
nt.Controls.Add(nl)
aeDetails.Tabs.Add(nt)
Return
End Select
sb.Append("<ul>")
For Each anRec In anList
sb.Append("<li><a onclick='MM_openBrWindow")
sb.Append("('announcementDetails.aspx?id=" & anRec.HVS_AR_Id & "','newWindow','status=yes,scrollbars=yes,resizable=yes,width=600,height=500'")
sb.Append("target='_blank' title='Click to view full contents of the announcements'>")
sb.Append(anRec.HVS_AR_AnnouncementTitle & "</a></li>")
Next
sb.Append("</ul>")
nl.Text = sb.ToString()
nt.Controls.Add(nl)
aeDetails.Tabs.Add(nt)
End Sub

I am having an issue with content page refresh, when I change something in master page. My scenario is, I have a login button present in master page, on click of which am loading a modal popup with login controls. Once the credentials are valid, i am hiding the modal popup and stroing the user authentication result in a Session object. In content page's page load event, I am checking for this session object, for showing/hiding some of the controls based on the user logged in.The problem is, after login, the content page is not getting reloaded and proper controls are not shown to the user. To make the content page refresh programmatically, i added an UpdatePanel in content page and refreshed it after login button click event in master page. But still content page is not getting refreshed.
btnLogin_Click(){
//Check login credentials
if(success){

I am a beginner to web development and ASP.NET. I am creating a web application (not public, so SEO, bookmarking etc. is of no concern) with the typical layout of header on top, Navigation on the left, content on the right. I want the content to update without the whole page reloading when selecting something on the navigation bar. What is the typical way to implement this? MasterPage with ContentPages and using an UpdatePanel (tried this, but does not seem to work, I guess because the URL is different for each content page)? Using Frames? Using an iFrame for the content part? UserControls for the content part
View 5 RepliesI have a command line C# server and an ASP.NET client, they both communicate via .NET Remoting. The server is sending the client still images grabbed from a webcam at say 2 frames a second. I can pass the images down to the client via a remote method call and the image ends up in this client method:
public void Update(System.Drawing.Image currentFrame)
{
// I need to display the currentFrame on my page.
}
How do i display the image on the a page without saving the image to the hard disc? If it was a winForms app i could pass currentFrame to a picturebox ie. picturebox.Image = currentFrame.The above Update method gets fired at least 2 times a second. If the client was a winForms app i could simply put picturebox.Image = currentFrame and the current frame on the screen would automatically get updated. How do i achieve the same effect with ASP.NET? Will the whole page need to be reloaded etc?
in my master page content place holder.
i have a grid which is going out of placeholder (as its bit bigger ), when page is loaded. i would prefer it to stay inside the placeholder or expand the placeholder.
Currently its going out side and when it moved out of placeholder it becomes transparent to the materpage default template.
I have an ASPX page with two columns. The left column has a GridView control that contains a list of article titles as LinkButton controls. When a LinkButton control is clicked, the content of the article is displayed in the right column. Each of the columns
is wrapped in an UpdatePanel. So far everything is working .
Each article title has further descriptive text that is defined in the code-behind as labels within a Div object. Each Div is added to a PlaceHolder object on the master page. References to the Div objects are added as attributes to the LinkButton so that JavaScript is executed when the user rolls over the title and the Div object with the descriptive text is displayed.
The rollovers are working fine and displaying the correct text for the first GridView page. However, when I click a button in the GridView's paging row to advance to the next page of the GridView list, the rollovers are not updated. The text is what was defined for the first GridView page of titles. How should I get the PlaceHolder objects to update when the UpdatePanels are updated?
I tried this much:-
protected void Page_PreInit(object sender, EventArgs e)
{
class1 obj = new class1();
DataTable dt = new DataTable();
dt = obj.get_text();
ContentPlaceHolder ContentPlaceHolder1 = ContentPlaceHolder)this.Master.FindControl("ContentPlaceHolder1");
ContentPlaceHolder1. ????
}
I have a ASP.NET page using a PlaceHolder. Grids are build programmatically and added to this PlaceHolder when the page is run. Example:
ASPX Code:
<asp:PlaceHolder ID="myPlaceHolder" runat="server" />
Code behind:foreach (var country in Tables.Countries())
{
var nGrid = BuildGrid(country.Code);[Code]....
This page works flawlessly in Opera and Firefox. Internet Explorer 8 shows me the "cannot display the webpage" screen.
I have created one web application with forms authentication.Whenever I logged in to the application and hit F5, it takes me to the login page instead refresh.
