Dont set it to invisible at design time. let it show, but on RowDatabound Event set its visibility to false and you will be able to retrieve it.

I recently upgraded an ASP.NET project from 2.0 to 3.5 framework, and I've had problems with my web deployment project ever since.
It no longer copies over existing files with the latest version. To remedy this problem I have had to manually uninstall the previous version before installing the latest version.
I tried removing the deployment project and creating a new one from scratch after the 3.5 upgrade, but have had no luck.
Has anyone else had this problem? I'm really baffled.
I'm tempted to create a custom action that will manually delete all files and subfolders before installing. Any other suggestions before I go down that path?

Sometimes a clean install is a better idea anyway, but make sure you have backed everything up before deleting.

Hello all
I am working on my one of my assignment to create ASP.NET AJAX project it's simple with one default.aspx page and on the middle of page there is one updatepanel and inside UpdatePanel there is on ImageBox and one Timer
I have one Image folder and there are 16 images and i want to display image in to imagebox in order from 1 to 16 and after 16th image it goes to image 1 and so on this is what i have done so far and it's working ok but still i want to do some thing in it
Dim MyImage(15) As String
Private Sub GetImages()
MyImage(0) = "1.png"
MyImage(1) = "2.png"
MyImage(2) = "3.png"
MyImage(3) = "4.png"
MyImage(4) = "5.png"
MyImage(5) = "6.png"
MyImage(6) = "7.png"
MyImage(7) = "8.png"
MyImage(8) = "9.png"
MyImage(9) = "10.png"
MyImage(10) = "11.png"
MyImage(11) = "12.png"
MyImage(12) = "13.png"
MyImage(13) = "14.png"
MyImage(14) = "15.png"
MyImage(15) = "16.png"
End Sub
Sub GetNextImage(ByVal Src As Object, ByVal Args As EventArgs)
'Retrieve the array from view state
MyImage = ViewState("PictureArray")
'Increment the image counter
ViewState("Counter") += 1
If ViewState("Counter") > 15 Then
ViewState("Counter") = 0
End If
'Assign the next image to the control
BannerImage.ImageUrl = MyImage(ViewState("Counter"))
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
'--Load as array with image ursl and save to view state
Call GetImages()
ViewState("PictureArray") = MyImage
'--Establish a counter to keep track of the array index
ViewState("Counter") = 0
BannerImage.ImageUrl = MyImage(ViewState("Counter"))
End If
End Sub
and HTML is like
<asp:UpdatePanel ID="BannerUpdatePanel" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer2" />
</Triggers>
<ContentTemplate>
<asp:Timer ID="Timer2" runat="server" Interval="250" OnTick="GetNextImage">
</asp:Timer>
<br />
<asp:Image ID="BannerImage" runat="server"
ImageUrl="~/Globe/1.png" />
</ContentTemplate>
</asp:UpdatePanel>
Now it's working ok but Imabebox flash too much and in the bottom left corner of web page it's keep showing downloading image url so how can i solve it and also it only flash when it change to next image and last is this the right way to do this or is there better way to do it.
Thank you

Really you don't even need AJAX to do this, simple JavaScript will handle this
var imageNum = 1;
setInterval(changeImage, 250);
function changeImage()
{
if( imageNum >= 16 )
imageNum = 1;
img.src = "http:\\mysite\" + imageNum + ".png";
imageNum++;
}

You should buy some books and read them

NONE of it is C#, it is javascript and cannot be changed to VB. Use it exactly as is.
Buy a book. Please.

A slight modification :
var imageNum = 1;
setInterval("changeImage()", 250);
function changeImage()
{
if( imageNum >= 16 )
imageNum = 1;
imageNum = parseInt(imageNum) + 1;
img.src = "http:\\mysite\" + imageNum + ".png";
}
Use this javascript to your page inside <script> tag.

<html>

function changeImage()
{

imageNum = 1;
img.src = "http:\\mysite\" + imageNum + ".png";
}
</script>
<body>
etc
You have been given everything you need. Now, you really need to pick up a book and learn something about html and javascript on your own.

You have been given a copy and paste solution. If you still can't make it work, or understand it, that indicates your level of competence is too low to be able to use good help. Which is your problem. Buy a book and read it, then come back.

What's the expression? We can make it idiot proof, but they keep making better idiots.

Why? imageNum is already integer.
Also, since imageNum is initialized as 1, parseInt(imageNum) + 1; would make it off by one.

Well Mark,
I agree, parseInt is not necessary.. I just used this for security purpose.
But if you dont increment imageNum, how could it change the image?
I think it should load 1.png, 2.png and so on... isnt it. 
|
|
|
|

True, I forgot. My response has been edited. The increment should be after the imageNum is used.

Hi All,

My question is i am loading the user control dynamically as follows.
step1:
--> In Defalut.aspx.cs--> page_Load i am written
--> Control uc = LoadControl("MyUserControl");
PlaceHolder.Controls.Add(uc);
step2: In UserControl there is GridView Control Need to bind the gridview only
in "Default.aspx.cs"
Can you please help me, how to bind the gridview control of usercontrol which is loaded and need to bind only in Defalut.aspx.cs
Thanks in Advance.

The way you normally would, assign the datasource and call DataBind.
Johndas wrote: need to bind only in Defalut.aspx.cs
Set the data source for the gridview to null in this case.

Make the gridview of the Usercontrol as public,
Add
uc.gridView.DataSource= yourdatasource;
uc.gridView.DataBind();
Or you can modify the control to handle this itself ..
