ASP.net MVC Tempdata getting DataSet's values out of it

Hey all I am new to the MVC world and was wanting to get a few values from the TempData that I made that houses 3 DataSet's inside it.

The values that are inside the TempData are these:

then selecting tTrip then rows then Results View:

enter image description here

finally seeing the DataSet values for tTrip:

enter image description here

I populate the TempData like so (simplify):

allData.Merge("tEvents"); //Gathers data and places it into tEvents
allData.Merge("tTrip"); //Gathers data and places it into tTrip
allData.Merge("tExternalTrainingMain"); //Gathers data and places it into tExternalTrainingMain

TempData["jsonData"] = allData;

I've tried:

string blah = TempData["jsonData"][0]["somename"].toString();

string blah = TempData["jsonData"][0].somename.toString();

string blah = TempData["jsonData"][0][0].somename.toString();

string blah = TempData["jsonData"][0][0][0].toString();

But only get errors. What is the proper way of getting the dataset values out of the TempData array?

Solution

  • The indexed property that gives you the value from TempData returns a object of type object. You need to cast your value to the desired type. For example:

    var myDataSet = TempData["jsonData"] as DataSet;
if(myDataSet != null)
{
    We have a dataset now!
    string blah = myDataSet.Tables[0]["somename"].toString();
}
