Accessing Gridview Cell Data with JavaScript

Hey there! I'm currently working on a gridview that includes a checkbox column. While I can easily determine whether a row is checked, I'm facing an issue trying to obtain the cell value using JavaScript. The reason behind my use of JS is due to the necessity of making an ajax call once I retrieve the cell value. Any help or insights would be greatly appreciated! Below is the code snippet:

function newData(mode) {
    if (mode == 'edit') {
        var valid = false; 
        var gv = document.getElementById("myGridview"); 

        for (var i = 0; i < gv.all.length; i++) { 
            var node = gv.all[i]; 
            if (node != null && node.type == "checkbox" && node.checked) { 
                valid = true; 
                break; 
            } 
        } 
        if (!valid) { 
            alert("Invalid. Please select a checkbox to continue."); 
        } 
        return valid; 
    }
}

Keep in mind that the ID of your GridView will be different once it is rendered as HTML, so you should update your code from document.getElementById("myGridview") to document.getElementById(myGridview.ClientID) in order to target the correct HTML table name.

If you encounter any issues, try troubleshooting the JavaScript using Firebug or the IE developer tool.

Enjoy coding!
