The error means what it says. And what it means is that you have zero idea about ASP.NET. If you knew anything at all, you'd know that server code runs on the server, and client code, on the client. Therefore, your code, if the framework let it run, would cause a message box to show on the server, thus freezing the server, and the client would see nothing, the website would time out.

Hi I want to make slideshow of four images. The javascript for slideshow is
<br />
<script language="JavaScript" type="text/javascript"><br />
<br />
var slideShowSpeed = 5000; <br />
var crossFadeDuration = 3;<br />
<br />
var Pic = new Array(); <br />
var PicUrl = new Array(); <br />
<br />
var PicCaption = new Array(); <br />
<br />
Pic[0] = 'images/image1.jpg';<br />
Pic[1] = 'images/image2.jpg';<br />
Pic[2] = 'images/image3.jpg';<br />
Pic[3] = 'images/image4.jpg';<br />
<br />
PicUrl[0] = '#';<br />
PicUrl[1] = '#';<br />
<br />
var PageNav='#';<br />
<br />
<br />
var m_intTimeOut;<br />
var j = 0;<br />
var m_intArrayLen = Pic.length;<br />
<br />
var preLoad = new Array();<br />
for (i = 0; i < m_intArrayLen; i++)<br />
{<br />
preLoad[i] = new Image();<br />
preLoad[i].src = Pic[i]<br />
}<br />
<br />
function runSlideShow(){<br />
if (document.all){<br />
document.images.SlideShow.style.filter="blendTrans(duration=2)";<br />
document.images.SlideShow.style.filter="blendTrans(duration=crossFadeDuration)";<br />
document.images.SlideShow.filters.blendTrans.Apply(); <br />
}<br />
document.images.SlideShow.src = preLoad[j].src;<br />
PageNav=PicUrl[j];<br />
<br />
if (document.all){<br />
document.images.SlideShow.filters.blendTrans.Play();<br />
}<br />
j = j + 1;<br />
if (j > (m_intArrayLen-1)) j=0<br />
m_intTimeOut = setTimeout('runSlideShow()', slideShowSpeed);<br />
}<br />
<br />
function pg_nav()<br />
{<br />
window.location.href=PageNav;<br />
}<br />
</script><br />

Install firebug and debug the JS. That is the way to go.

Hi Navaneeth ,
Thanks for giving this idea. i have installed the debugger bt im unable to debug my javascript. My javascript is on the aspx page and is called on body's onload event.
How ill debug it.
|
|
|
|

It's incredibly easy, and there are pages explaining how to use firebug. Of COURSE the JS is in your aspx page. You set a breakpoint, refresh the page, and it will stop and you can step through.

Hi, I have a treeview control.On Page Load I am populating this Treeview through code.
The TreeView contains one parent node and this parent node contains several child nodes.
My problem is that on Treeview_SelectedNodeChanged event Whenever I am selecting a child node,it automatically selects the first child node only.
I am after this for last 2 days.I have worked with TreeView several times, but never faced such problem.
Please Help.

Hi everybody,
My requirement is i have two panels in which having records in repeaters or labels i want to move record from one panel to another like moving records from one list box to another is there any control to perform this task?
Thanks.

Not built in, no. A panel is just a div, it doesn't actually mean anything, in HTML, apart from a place holder. You're going to have to write javascript to do this. I'm not sure how much viewstate is going to help with postback recording what you've done, either.

Hi All,
Here is my requirement,
I am developing a web site where a consumer can see his water bills online. page contain Bill's image in the background say bill.aspx.
on that image I am showing his related data from database.
when user click on button (say show my bill) bill.aspx is shown. when bill.aspx is shown a problem arises, that data from sql is shown first, and then image of the bill is loaded, which looks odd. so my client wants to show this page as pdf in browser. as i dont have pdf files , all my record is fetching from database dynemically. please guid me to show my bill.aspx page as pdf in browser.
regards .

You will need to buy a library that generates PDFs, then write those down to the browser.

This is the third time you are asking the same question !!

What do you mean by not working proper?

shijivijayan wrote: .the splitting is not working proper
Yes, it is. It will split based on whatever character you give it. The square means there's a control character in your strings, instead of a space.
If this is homework, you should talk to your teacher. If it's paid work, you should be bloody ashamed of yourself. We are happy to help people, but for someone of this skill level to charge for their 'efforts', is a disgrace.

hi all,
I am using VS 2005,C# with framework 2.0 and AJAX toolkit. I got a datagridview and already create a CommandField, button type. I would like to display particular row details by modalpopup extender.
Currently i am using code behind (gridview_SelectedIndexChanged to get neccesarry data) and method modalpopupextender.Show() to acheive it,but its is pretty slow when browse via internet (its ok if browse locally). My coding is show like below:
aspx:
<asp:GridView ID="DataGridProduct" runat="server" <code>OnSelectedIndexChanged="DataGridProduct_SelectedIndexChanged"</code> AutoGenerateColumns="False">
<Columns>
<asp:CommandField ButtonType="Image" ShowSelectButton="True" HeaderText="View" />
<asp:BoundField DataField="ProdCode" HeaderText="Code" ReadOnly="True" SortExpression="ProdCode"
</asp:BoundField>
<asp:BoundField DataField="ProdDesc" Visible="False" />
<asp:TemplateField>
<HeaderTemplate>Description</HeaderTemplate>
<ItemTemplate><%# Limit(Eval("ProdDesc"),25)%></ItemTemplate>
</asp:TemplateField>
</Columns>
modalpopup
<cc1:ModalPopupExtender <code>ID="mpeProduct"</code> runat="server" TargetControlID="Button1" PopupControlID="panelProduct" CancelControlID="btnClose" BackgroundCssClass="modalBackground" PopupDragHandleControlID="panelDrag" Drag="true">
</cc1:ModalPopupExtender>
aspx.cs
protected void DataGridProduct_SelectedIndexChanged(object sender, EventArgs e)
{
if (DataGridProduct.SelectedDataKey[4].ToString() == "Horizontal")
{
lblProductCode.Text = DataGridProduct.SelectedDataKey[0].ToString();
lblProductName.Text = DataGridProduct.SelectedDataKey[1].ToString();
txtProductSpec.Text = DataGridProduct.SelectedDataKey[2].ToString();
txtProductDescription.Text = DataGridProduct.SelectedDataKey[3].ToString();
ImgDisplay.ImageUrl = DataGridProduct.SelectedDataKey[5].ToString().Trim();
<code>mpeProduct.Show();</code>
}
}
so,can i use client script to acheive it, get datagridrow's data and display in modalpopup extender?
any advice and tips are welcome,
thanks in advance
