how to show tooltip in gridview cell mousemove or click event
Javascript code to show tooltip:
function mouseXY(e, val) {
var posx = 0;
var posy = 0;
if (e.pageX || e.pageY) {
posx = e.pageX + 5;
posy = e.pageY;
}
else if (e.clientX || e.clientY) {
posx = e.clientX + 5;
posy = e.clientY;
}
//set current cells value in tooltip
document.getElementById(“lblToolTip”).innerText = val.innerText;
//set current position of div to show as tooltip at mouse position
document.getElementById(“movingDiv”).style.right = posy + “px”;
document.getElementById(“movingDiv”).style.left = posx + “px”;
document.getElementById(“movingDiv”).style.top = posy + “px”;
