How to find all controls in Gridview?
TextBox txtItem = (TextBox)Grid1.Rows[Grid1.EditIndex].FindControl("txtItem");

foreach(Control c in Grid1.Rows[Grid1.EditIndex].Controls)
{
    // do stuff in here.

}

function edit(this)
{
   var textboxID = $(this).parent().find("[id$='textBoxId']");
}

foreach ( GridViewRow row in MyGridView.Rows )
{
    TextBox myTextBox = (TextBox)row.FindControl("myTextBox");
}

var listOfControls = Utility.FindControlsOfType<TextBox>(yourGridRow);

public static class Utility
{
    public static List<T> FindControlsOfType<T>(Control ctlRoot)
    {
        List<T> controlsFound = new List<T>();

        if (typeof(T).IsInstanceOfType(ctlRoot))
            controlsFound.Add((T)(object)ctlRoot);

        foreach (Control ctlTemp in ctlRoot.Controls)
        {
            controlsFound.AddRange(FindControlsOfType<T>(ctlTemp));
        }

        return controlsFound;
    }
}
