Does it mean that you want to show the Select one as first in drop down list
Write this line
DropDowmList2.Items.Insert(0, new ListItem("Select One"));
Thanks and Regards

When showing popup pass the checkbox id to that page. And from the popup page use javascript's parent property to set the chekbox checked.

I have several reports created. I want to get them to stretch to the width of the ReportViewer control.
Currently they remain a static width and on some machines they show squeezed up.
Is there a way to get the reports to either dynamically change with the Browser (like the reportviewer control does, or to make the reports be the size of the viewer by default?
Thanks for any tips!

Tried Zoom but it doesn't do anything like I want.
I basically need the report to behave like a webpage; when you resize the browser window the page resizes along.
Anyone have ideas about this, is there a setting I'm missing?
Thanks!

This is the answer:
ReportViewer.AsyncRendering = false
ReportViewer.SizeToReportContent = true

Hi Guys,
This is a newbie type question for ya.
I have a datalist on a usercontrol, that is bound to an object datasource.
What I want to do is display a default message if the objsource does not return any records,
|
|
|
|
|
Not sure I understand, but I think what you're asking is how to find out the number of rows in a datalist? Look for List.Rows.Count, and then take action (such as hiding the list and showing a div) depending on the result...
Or have I misunderstood you?

hi
i wanted to build a print button in asp.net 2.0
i wrote the following code
"codebehind"
<br />
<br />
protected void Button1_Click(object sender, EventArgs e)<br />
{<br />
Button1.Attributes.Add("onClick","window.print()");<br />
Button1.Visible = false;<br />
<br />
}
now.. the button does disappear, but the print window doesnt come up.
please help.. and i dont want a html input button.

For this code to work you need to add the attributes before the button is clicked.
So on the page load event do
if (!IsPostback)
{
Button1.Attributes.Add("onClick","window.print()");
}
Then it should work like you want it to.
Hope that helps.

the thing worked, but theer`s a little problem.
i want the button to go invisible, so that when the printing is done, the button does not show up.
right now as i click the button, the print window comes, and then the button goes invisible.

You might want to get rid of the codebehind and do something like this:
Change this line:
Button1.Attributes.Add("onClick","window.print()");
to:
Button1.Attributes.Add("onClick","document.getElementById("+Button1.ClientId+").style.visibility = 'hidden';window.print();");
I think that should work for you.

did get rid of the codebehind, removed the defintion for "Button1_Click".
and placed the following code in the page_load event
if (!IsPostBack)
{
Button1.Attributes.Add("onClick", "document.getElementById(" + Button1.ClientID + ").style.visibility = 'hidden';window.print();");
}
but nothing seems to happen at all. nor does the button disappear, and neither does the print window come up

Ok I did a little playing. It looks like you will need to create a javascript funciton.
In the header section of your html page you need this function:
<head runat="server">
<title>Your page name here</title>
<script type="text/javascript" >
function doPrint(button)
{
button.style.visibility = "hidden";
window.print();
return false;
}
</script>
</head>
Then in the page load event do this:
Button1.Attributes.Add("onClick", "return doPrint(" + Button1.ClientID + ");");
That will work.
NOTE as soon as your page posts back to the server the print button will show up again.
Hope that helps.
Ben

Why don't you comment the first line and uncomment the commented line ? I don't think that HTML input hidden field is having innerText Property ! 
My suggestion is make the HidTemp to runat server. Then you can easily get the value on server side.

I think this will work only on IE...
