Bind Data To Grid View From Different Data Sources

Introduction

In this blog, I have tried my best, to create different data sources and bind them to the GridView since data source and Grid View are very important to work in any application. In the future, if I have found any other datasource, I  will append it to this write-up. Hope it will be a good reference or starting point for beginners.

Bind Gridview Using Array with class

First, create a class.

public class intializeheaderformat {
    public int id {
        get;
        set;
    }
    public string worksheetname {
        get;
        set;
    }
    public string headerformat {
        get;
        set;
    }
    public intializeheaderformat(int id, string wsname, string hf) {
        id = id;
        worksheetname = wsname;
        headerformat = hf;
    }
}

Declare and Initialize array like below

Array IHF = new [] {
    new intializeheaderformat(1, "test", "a|b|C"), new intializeheaderformat(2, "test1", "d|e|f")
};
GridView1.DataSource = IHF;
GridView1.DataBind();

Output



Bind Grid view Using One Dimensional Array

Code

string[] arnames = {
    "karthik",
    "sachin",
    "dravid"
};
GridView1.DataSource = arnames;
GridView1.DataBind();

Output



Bind Gridview Using Two Dimensional Array

Code

string[, ] arnameswithid = {
    {
        "1",
        "karthik"
    },
    {
        "2",
        "sachin"
    },
    {
        "3",
        "dravid"
    }
};
ArrayList arrList = new ArrayList();
for (int i = 0; i < 3; i++) {
    arrList.Add(new ListItem(arnameswithid[i, 0], arnameswithid[i, 1]));
}
GridView1.DataSource = arrList;
GridView1.DataBind();

Output



Note

If we try to bind two/multi dimensional data directly to GridView, then we will get an exception with the message below.

Array was not a one-dimensional array

Bind Gridview Using Multi Dimensional Array

Code

string[, ] arrtable = {
    {
        "1",
        "karthik",
        "programmer"
    },
    {
        "2",
        "sachin",
        "CA"
    },
    {
        "3",
        "dravid",
        "doctor"
    }
};
DataTable tempdttogetarray = new DataTable();
tempdttogetarray.Columns.Add("ID", typeof(string));
tempdttogetarray.Columns.Add("Name", typeof(string));
tempdttogetarray.Columns.Add("desgination", typeof(string));
for (int row = 0; row < arrtable.GetLength(0); row++) {
    tempdttogetarray.Rows.Add();
    tempdttogetarray.Rows[tempdttogetarray.Rows.Count - 1]["ID"] = arrtable[row, 0];
    tempdttogetarray.Rows[tempdttogetarray.Rows.Count - 1]["Name"] = arrtable[row, 1];
    tempdttogetarray.Rows[tempdttogetarray.Rows.Count - 1]["desgination"] = arrtable[row, 2];
}
GridView1.DataSource = tempdttogetarray;
GridView1.DataBind();

Output



Bind Gridview Using ArrayList

Create class

public class intializeheaderformat {
    //fields
    public int _id {
        get;
        set;
    }
    public string _worksheetname {
        get;
        set;
    }
    public string _headerformat {
        get;
        set;
    }
    public intializeheaderformat(int id, string wsname, string hf) {
        _id = id;
        _worksheetname = wsname;
        _headerformat = hf;
    }
}

Create Arraylist

ArrayList IHF = new ArrayList();
intializeheaderformat objinitheader = new intializeheaderformat(102, "test2.xls", "d|e|f");
IHF.Add(objinitheader);
objinitheader = new intializeheaderformat(103, "test3.xls", "H|e|f");
IHF.Add(objinitheader);
GridView1.DataSource = IHF;
GridView1.DataBind();

Output



Bind Gridview Using GenericList

Create Class: public class intializeheaderformat {
    //fields
    public int _id {
        get;
        set;
    }
    public string _worksheetname {
        get;
        set;
    }
    public string _headerformat {
        get;
        set;
    }
    public intializeheaderformat(int id, string wsname, string hf) {
        _id = id;
        _worksheetname = wsname;
        _headerformat = hf;
    }
}

Create Generic list

List < intializeheaderformat > lstworksheetformat = new List < intializeheaderformat > ();
intializeheaderformat objinitheader = new intializeheaderformat(101, "test1.xls", "a|b|c");
//(or)
//objinitheader._id = 101;
//objinitheader._worksheetname = "test1.xlsx";
//objinitheader._headerformat = "a|b|c";
lstworksheetformat.Add(objinitheader);
objinitheader = new intializeheaderformat(102, "test2.xls", "d|e|f");
lstworksheetformat.Add(objinitheader);
objinitheader = new intializeheaderformat(103, "test3.xls", "g|h|i");
lstworksheetformat.Add(objinitheader);
GridView1.DataSource = lstworksheetformat;
GridView1.DataBind();

Output



Bind Gridview Using DataTable

Create DataTable

DataTable intializeheaderformat = new DataTable();
intializeheaderformat.Columns.Add("Id", typeof(int));
intializeheaderformat.Columns.Add("worksheetname", typeof(string));
intializeheaderformat.Columns.Add("headerformat", typeof(string));
intializeheaderformat.Rows.Add(1, "test1.xls", "a|b|c");
intializeheaderformat.Rows.Add(2, "test2.xls", "d|e|f");
intializeheaderformat.Rows.Add(3, "test3.xls", "g|h|i");
GridView1.DataSource = intializeheaderformat;
GridView1.DataBind();

Output



Bind Gridview Using Linq Query Result:

Linq Creation - The Three Parts of a LINQ Query

1. Data source
   

   List < intializeheaderformat > lstworksheetformat = new List < intializeheaderformat > ();
   intializeheaderformat objinitheader = new intializeheaderformat(101, "test1.xls", "a|b|c");
   lstworksheetformat.Add(objinitheader);
   objinitheader = new intializeheaderformat(102, "test2.xls", "d|e|f");
   lstworksheetformat.Add(objinitheader);
   objinitheader = new intializeheaderformat(103, "test3.xls", "g|h|i");
   lstworksheetformat.Add(objinitheader);

2. Query creation
   

   //Linq query syntax -justfYI
   // from – data source to tempvar
   //where – Conditional
   //orderby -sorting
   //select – column selection
   //group – groupby
   var temptable = from tempresult in lstworksheetformat select new {
       tempresult._id, tempresult._headerformat
   };

3. Query execution
   

   GridView1.DataSource = temptable;
   GridView1.DataBind();

   Output
   
   
   

Bind Gridview using XML Datasource

XML << ? xml version = "1.0"
encoding = "utf-8" ? > < workbook > < sheet > < Id > 101 < /Id> < WorkSheetName > test1 < /WorkSheetName > < Format > A | B | C < /Format> < /sheet > < sheet > < Id > 102 < /Id> < WorkSheetName > test2 < /WorkSheetName > < Format > D | E | F < /Format> < /sheet > < sheet > < Id > 103 < /Id> < WorkSheetName > test3 < /WorkSheetName > < Format > G | H | I < /Format> < /sheet > < /workbook>

Code

DataSet ds = new DataSet("Worksheetformat");
ds.ReadXml(Server.MapPath("~/Format.xml"));
GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();

Output
