Question

basically my aim is to use JQuery to post back an x & y mouse co-ordinate to my controller where the 2 values are added to an array/list which is then added to the session.

I want to iterate through a series of 60 clicks (and subsequently postbacks to the controller) before building an XML string with each co-ordinate in it.

Something along the lines of this:

<xml>
<click1>
 <xpos>45</xpos>
 <ypos>55</ypos>
</click1>
<click2>
 <xpos>45</xpos>
 <ypos>55</ypos>
</click2>
</xml>

I’m unsure as to how best to store the individual mouse clicks after each postback, and I thought perhaps a session and a multi-dimensional array/list would be good for this? I’m also a little confused as to how to convert the session back into a list and assemble the XML as required.

Could anyone point me in the right direction?

Many thanks!

Answer 1

I solved this by creating a Dictionary of type , with MouseCoordinates referring to a class which accepted 2 string values for xposition and yposition.

I then placed the Dictionary into a session, re-casting it as a Dict when I needed to add a new value to it.

Finally I looped through the Dictionary at the end of my cycle of clicks retrieving all the values.

I hope this code helps someone:

var coords = new Dictionary<int, MouseCoordinates>();

HttpContext.Session.Add("coords", coords);

// Accessing Dictionary From Session
var coords = (Dictionary<int, MouseCoordinates>)HttpContext.Session["coords"];

// Adding Values using a integer stage that's posted back to the controller
coords.Add(currentStage, new MouseCoordinates { xposition = xpos, yposition = ypos });

// Looping through the session at the end of the cycle
            foreach (var ords in coords)
            {
                var qnode = ords.Key;
                var xvalue = ords.Value.xposition;
                var yvalue = ords.Value.yposition;
            }
