Add Datarow In Datatable At Specified Index

During website development in asp.net,  sometimes we need to manage data-table according to our need like modify records in data-table, adding new record etc.In this post I will show you how we can insert generic data in the data-table, sometimes mix types of values being returned by data-table(using stored procedure), so I am going to show you how we can insert data at the particular row.

        // Adding New row in data-table
        var row = new object[] { "0", "00000", "n/a", "n/a", DateTime.Now, "Create New Patient", 0, 0, 0, "n/a", "n/a", "n,a", "n/a" };
        var newRow = patients.NewRow(); // patients is the object of the data-table
        newRow.ItemArray = row;
        patients.Rows.InsertAt(newRow, 0);

        //Binding the Combobox
        cmbPatients.DataSource = patients;
        cmbPatients.DataBind();

In above code I am first creating the array of object type,  I am creating the array because this will also helpful in case when we’re using the Stored Procedure, so in this case we don’t know about the exact type of the values which being returned in data-table, so object array would be helpful to handle this case.

Next I created the new row of the data-table type, after this I assigned the object array to the row and finally inserted this newly created row at the 0 Index, means first row.

Another way to add Datarow in DataTable

We can also insert data for selected columns, except insert all data at once, I am going to show how we can do this.

        // Adding New row in data-table
        var newRow = patients.NewRow(); // patients is the object of the data-table
        newRow["ColumnName"] = "Your Values";
        newRow["ColumnName1"] = "Your Values";
        patients.Rows.InsertAt(newRow, 0);

        //Binding the Combobox
        cmbPatients.DataSource = patients;
        cmbPatients.DataBind();

So you noticed that in this case I am only assigning the values for selected columns not for all. You can use either of ways according to your need. Hop you will enjoy this.
