Ajax ModalPopupExtender with DataGrid bound Hyperlink - c#

I am currently developing an ASP.net c# application. I have an Ajax Modal Popup Extender which I currently have working with an asp:button for testing purposes which I have got working fine.
However, what I need to be able to do is I have a hyperlink bound to a dataset being populated from a MySQL Database. The hyperlink passes parameters based on database columns. What I need to be able to do is to open the modal popup extender and display dynamic data based on the paramaters from the hyperlink url.
Hope this makes sense, thanks for any help you can provide.

If it is a LinkButton, open the ModalPopup in the click event of the LinkButton by calling the Show method. Process any data that you want to display in the panel before you display it.

modal popup after post back c#

I have one requirement like,
One master page with three image buttons, once clicking on any button it redirect's to appropriate page, in that page(it's requester form) i have placed all controls in one panel control(id="MyPanel"), one link button(MyLinkButton) out side to that panel and one modal popup control(id=MyModalpopup) as target control id=MyLinkButton,popupcontrolid=MyPanel. On this page load i did code (MyModalpopup.show()) to show all controls in modal popup.
every thing is working fine but, i have controls like dropdown,checkboxlist with autopostback=true and these are in updatepanel and for these controls i am binding data from code behind. Now the problem here is the data i am unable to bind and when these controls are postback the modal popup is not visible.
i am using C# and 3.5 framework.
What I would do, is have a hidden field (with runat=server) that has a true/false value that is set when the modal is activated/hidden.
Then during the client-side page-load of the postback, read that value and make the modal hidden/shown appropriately.
The other option would be to figure out how to make those controls work without the auto-postback (i.e. populating the controls via ajax).

How to send the content of a line of the GridView to another page?

I have a GridView with some BoundFields and one Button inside the grid.
I'd like to fire the OnClick event of the button to open a new window and also get the content of that whole line to edit it ... How Could I do that ?
I dont want to use QueryString and I think Sessionisn't the best way so is there an other safe way to do that ?
Obs: I get the content of my GridView from my DataBase using a SqlDataSource inside the aspx page. Its a little harder for me than for the most people because I used to programm on WebForms, it's the first time i'm working with web =\
I solved using Sessions:
Session["login"].ToString() = TxtLogin.ToString();
and do retrieve the information:
TxtTeste.Text = Session["login"].ToString();

Creating a form inside a gridview

I currently have a gridview with data that is binded from the database. This data is suppose to be editable and deleteable.
Is it possible to create a form within the grid view?
ie when you click on an item in the gridview, everything below or above moves down/up to create some room for a new editing pane with two dropdownlist and a few icons for delete/update.
Any suggestions?
The gridview itself has some features to edit, add, delete etc. Check this out http://msdn.microsoft.com/en-us/library/ms972948.aspx. It has kind of a learning curve though, so you must read to be able to do cool stuff with the Gridview.
I have seen that sort of functionality with Telerik's grid controlTelerik ASP.NET Grid.
You can open a modal popup on eidt/insert if your form fields are many otherwise gridview's inbuilt editing would do just fine.

Get and set data in an asp panel using modal popup extender

I am trying to get data from a data grid and display it into a modal panel. Then modify data in modal panel and after the panel was closed using the "ok action" the modified data to be displayed again in data grid.
This seems to be like a true horror... i do not want to post some code because is really a lot.
The first problem was that the button which opens the modal panel does not call its code behind on server so i do not know how to populate the fields from modal panel with the ones from data grid.
And the second was that the "ok" and "cancel" buttons from modal panel also does not call any code behind from server... so i could not update the data grid with new modified values from modal panel.
Please if you know some tutorials about this, or have an idea how to enable those calls on server side, give me a hand, i seek some but all of them seems to be only for "educative" purposes.
Thanks !

Dynamic Drop Down List ASP.net

How can I create a dynamic drop down list without using AutoPostBack. I ask because I just want to change the value of what the second drop down list displays and then the user clicks a button and it submits. But If I use AutoPostBack then it postbacks to page and runs code that shouldn't be run until that final box has been selected. (I use Postback in the other part of my program so using !IsPostBack isnt a option.) I looked at Javascript but ASP generates all of its controls names at runtime. What can I do? I have looked at the Ajax CascadingDropDown control but my problem with that is it contained in a XML file or a Database, I need this to be contained inside my Page. Any Ideas?
You can use the CascadingDropDown control from the AJAX Control Toolkit
Maybe this example will help? It's part of the ASP.NET AJAX Control Toolkit available here.
You can use AJAX to get the values for the second drop down list, based on the selected value of the first. Add a onchange event handler on the client-side to the first drop down list that makes the AJAX call and fills the second on success.
