Insert a new row into DataTable

Question

I have a datatable filled with staff data like..

Staff 1 - Day 1 - Total
Staff 1 - Day 2 - Total
Staff 1 - Day 3 - Total
Staff 2 - Day 1 - Total
Staff 2 - Day 2 - Total
Staff 2 - Day 3 - Total
Staff 2 - Day 4 - Total

I want to modify so that the result would be sth like..

Staff 1 - Day 1 - Total
Staff 1 - Day 2 - Total
Staff 1 - Day 3 - Total
Total   -       - Total Value
Staff 2 - Day 1 - Total
Staff 2 - Day 2 - Total
Staff 2 - Day 3 - Total
Staff 2 - Day 4 - Total
Total   -       - Total Value

to be concluded, I need to insert the total row at the end of each staff record.

So, my question is how to insert a row into a datatable? Tkz..

Answer 1

@William You can use NewRow method of the datatable to get a blank datarow and with the schema as that of the datatable. You can populate this datarow and then add the row to the datatable using .Rows.Add(DataRow) OR .Rows.InsertAt(DataRow, Position). The following is a stub code which you can modify as per your convenience.

//Creating dummy datatable for testing
DataTable dt = new DataTable();
DataColumn dc = new DataColumn("col1", typeof(String));
dt.Columns.Add(dc);

dc = new DataColumn("col2", typeof(String));
dt.Columns.Add(dc);

dc = new DataColumn("col3", typeof(String));
dt.Columns.Add(dc);

dc = new DataColumn("col4", typeof(String));
dt.Columns.Add(dc);

DataRow dr = dt.NewRow();

dr[0] = "coldata1";
dr[1] = "coldata2";
dr[2] = "coldata3";
dr[3] = "coldata4";

dt.Rows.Add(dr);//this will add the row at the end of the datatable
//OR
int yourPosition = 0;
dt.Rows.InsertAt(dr, yourPosition);

Answer 2

// get the data table
DataTable dt = ...;

// generate the data you want to insert
DataRow toInsert = dt.NewRow();

// insert in the desired place
dt.Rows.InsertAt(toInsert, index);

Answer 3

// create table
var dt = new System.Data.DataTable("tableName");

// create fields
dt.Columns.Add("field1", typeof(int));
dt.Columns.Add("field2", typeof(string));
dt.Columns.Add("field3", typeof(DateTime));

// insert row values
dt.Rows.Add(new Object[]{
                123456,
                "test",
                DateTime.Now
           });

Answer 4

You can do this, I am using

DataTable 1.10.5

using this code:

var versionNo = $.fn.dataTable.version;
alert(versionNo);

This is how I insert new record on my DataTable using row.add (My table has 10 columns), which can also includes HTML tag elements:

function fncInsertNew() {
            var table = $('#tblRecord').DataTable();

            table.row.add([
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "2011/04/25",
                    "Edinburgh",
                    "5421",
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "<p>Hello</p>"
            ]).draw();
        }

For multiple inserts at the same time, use rows.add instead:

var table = $('#tblRecord').DataTable();

table.rows.add( [ {
        "Tiger Nixon",
        "System Architect",
        "$3,120",
        "2011/04/25",
        "Edinburgh",
        "5421"
    }, {
        "Garrett Winters",
        "Director",
        "$5,300",
        "2011/07/25",
        "Edinburgh",
        "8422"
    }]).draw();

Answer 5

In c# following code insert data into datatable on specified position

DataTable dt = new DataTable();
dt.Columns.Add("SL");
dt.Columns.Add("Amount");

dt.rows.add(1, 1000)
dt.rows.add(2, 2000)

dt.Rows.InsertAt(dt.NewRow(), 3);

var rowPosition = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("SL")] = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("Amount")] = 3000;
