I need to show Sharepoint 2010 like pop-up window when clicked on a link in grid view. Once the modal pop-up displayed and user selected the Save button data base should be updated with given values in pop-up. How can I get this. Any Idea.

As of now I am using below code to get it but no idea how to pass the values to Database once clicked on the button in pop-up

Note: As of now I am not adding the gridview code here as I wanted to achieve it first with sample html then wanted to do with grid view.

Java Script

function openDialog() {

    var options = {

        html: divModalDialogContent,  // ID of the HTML tag

        // or HTML content to be displayed in modal dialog

        width: 600,

        height: 300,

        title: "My First Modal Dialog",

        dialogReturnValueCallback: dialogCallbackMethod,  // custom callback function

        allowMaximize: true,

        showClose: true

    };

    SP.UI.ModalDialog.showModalDialog(options);

}

//Results displayed if 'OK' or 'Cancel' button is clicked if the html content has 'OK' and 'Cancel' buttons

function onDialogClose(dialogResult, returnValue) {

    if (dialogResult == SP.UI.DialogResult.OK) {

        alert('Ok!');

    }

    if (dialogResult == SP.UI.DialogResult.cancel) {

        alert('Cancel');

    }

}

// Custom callback function after the dialog is closed

function dialogCallbackMethod() {

    alert('Callback method of modal dialog!');

}

HTML

<div id="divModalDialogContent">

    Hello World!

    <input type="button" value="OK"onclick="SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.OK, 'Ok clicked'); return false;"

        class="ms-ButtonHeightWidth" />

    <input type="button" value="Cancel"onclick="SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.cancel, 'Cancel clicked'); return false;"

        class="ms-ButtonHeightWidth" />

        <asp:Button runat="server" ID="btnClicked" Text="Clicked" 
        onclick="btnClicked_Click" />

<input type="button" value="Open" onclick="openDialog()" />

How can I call db upon clicking 'clicked' button in pop-up. Also I need to send parameters to pop-up

Thanks in advance
