Modal popup search window to replace dropdown control ASP.NET - asp.net

I'm looking for the simplest way of popping a modal search window on top of an ASP.NET 3.5 application to look up values for a field. I've got a screen for users to add courses; users need to be able to choose an instructor by searching for instructors in a popup.
So - the popup would have a textbox and a gridview with results; clicking the "choose" button in a result would populate the instructor field on the calling form.
What's the simplest way to achieve this?

Try using jQuery inside a UserControl with something like the tutorial from yensdesign.
The UserControl I created with this approach provided the user the option to set their preferences for the site. I found with this approach it was easier to control the interaction between the modal window and the calling window than calling a new popup browser window. One also doesn't have to worry about popup blockers getting in the way.
Is this helpful or are you looking for more detail?

A very simple approach would be to add javascript to your page to popup a new browser window dialog, something like this:
function fnFieldSearch(searchURL)
{
var wndSearch = window.open(searchURL,"SearchPopup","toolbar=yes,width=600,height=400,directories=no,status=yes,scrollbars=yes,resizable=yes,menubar=no");
wndSearch.focus();
}
On the modal search page, use javascript to send the search value back:
window.opener.document.FormName.ControlName.value = 'whatever';

Think about using an IFrame to achieve this, from the sounds of what you are talking an IFrame would suffice and provided the needed functionality.
<iframe src="YOUR PAGE HERE"></iframe>
There's a lot more you can do with it, these are just the tags to get you going.

Can I have a modal dialog from asp.net gridview edit click?

I am wondering if it is possible to have a modal dialog (like JQuery) by clicking Edit button on a asp.net built in gridview control. If yes, can anymore point me out the brief process of how it could be done. Please see the picture below for clarification.
Thanks.
I see few ways to do that:
Using OnEditCommand property (assuming you are using <asp:EditCommandColumn to draw that edit link):
You can show popup using serverside handler (for instance, popup included into ajaxcontroltoolkit.dll which allows to show popup from serverside easily on page reload)
Another option:
Make your own column with edit link for each item. It can have OnClientClick handler which will open jQuery popup directly on client (but you will need to get row info for current line from server somehow: with your own ajax call or, suppose it will be better, using webservice with webmethod)
Second option could be modified: instead of creating own column, you may add click even handler with that same jquery on default edit link with return false, so it will prevent form submition.
I never did something like this personally and even newer saw implementations of such thing, but I would select some option from those listed above. I do not think that there is some really simply, built in way of doing that.
UPD:
Here is an example of opening popup with own edit button and modalpopupextender from ajax control toolkit (similar like in my first option except that they are using own edit button, which I think could be easily replaced by default one and OnEditCommand even handler) :

Open aspx page in modal popup

I have an aspx page (let say page1.aspx) having labels and buttons on it. In some other page i need to show content of page1.aspx in modal popup. I have read many articles, but did't find exact solution. Some of the possible ideas are, 1: create Usercontrol, 2: Use Server.execute() method.
Please suggest any solution. Thanks
If you simply want to show a popup (a modal dialog) you can create an user control which contains the markup form page1.aspx and use either AjaxControlTookit (ModalPopup) or jQuery.dialog
I prefer the jQuery.Dialog, it saves 2 postbacks to the server and is easier to integrate.
Here is how to integrate it with ASP .Net, a little trick so the inputs inside that dialog will be posted to server, when the button is clicked.

Custom Popup Dialog Asp.Net

I'd like to create email dialog that has several inputs including message textbox plus some other custom info. I'd like it to display center screen over top of main page setting the opacity to like 50%.
do i create the pop up as anohter aspx page or panel?
Not sure what to use here, z-index, modalPopupExtender, Javascript, jquery. looking for easy and something stable.
I would look into the ModalPopupExtender in the AJAX Toolkit.
You can also try creating the dialog with jQuery. If you decide to go that route, check out the jQuery UI dialog:

LinkButton alternative? (Need it to function like a normal link)

LinkButtons are giving me headaches. I thought, foolishly, that they allowed you to create programmatic links. Obviously this is not the case (by design), as they have behave nothing like normal links - you can't see your address when you hover over them, you can't open them in a new tab, etc.
Is there an alternative in .NET that actually lets you programmatically create a true HTML link? The ability to open multiple items in tabs is sort of a requirement. I've looked into styling a Button to look like a link, but it still behaves like a button, so this won't work either. Any ideas?
EDIT: Sorry, forgot: can't use HyperLink, as I need the ability to send CommandArguments, set OnClick events, etc. It needs to function as a button still.
The HyperLink control.
Set the href using the NavigateUrl property, and tagets (for new windows/tabs) can be set using the Target property
Edit to respond to question edit
I'm not really sure what you're after - your question is asking for a control that "functions like a normal link", so that clicking on it can open in a new window/tab, but your edit says you want to be submitting CommandArguments and using the OnClick event - so not a normal link.
The problem you've got here is that the PostBack processing of command arguments and OnClick events happens at the server, but the "open in a new window" happens on the client (using the "target" attribute of the anchor tag, or possibly with JavaScript) - these two don't really mix all that well.
A couple of options spring to mind:
Use a LinkButton, and if you handle a PostBack, output some JavaScript to open the new page in a new window.
Use a HyperLink control with a target and set the "CommandArguments" as a querystring element to the link - you can then process that on the catching page that opens in the new tab.
You can also cause JavaScript to fire onClick using the Attributes collection:
// Create a hyperlink
HyperLink link = new HyperLink();
link.NavigateUrl = "/somepage.aspx?arg=First";
link.Target = "_blank"; // Open in a new window
// Add a client side onClick event calling someMethod function with a reference
// to the link, and making sure the link processing stops.
link.Attributes.Add("onClick", "someMethod(this);return false");
You mean HyperLink?
Of course you could always use the a tag in HTML.
EDIT: When you hover over a link, the browser displays the target. When you hover over a LinkButton, the browser displays the javascript call that will execute the function server side. I'd say the best you can do is display the target page in the ToolTip, since I think it would be pretty tough to display it in the browser.
If you use a LinkButton you will be able to set the command arguments and the onclick method in your code behind. By doing so, you will no longer be able to open the link in a new window as you have found out.
One of the reasons that you cannot open a LinkButton in a new window is because it is doing a postback to the same page.
I think you either have to use a HyperLink control and pass the command argument as a query string parameter or use a LinkButton control and loose the open in a new tab functionality.
If you pass the argument as a query string parameter, then you can check for that param in page load and still call your onclick function which you were going to use for your LinkButton.
Hope this is clear and it helps you.
